Subject: dt-bindings: ath10k: Add new dt entries to identify coex support

This adds new dt entries qcom,coexist-support and qcom,coexist-gpio-pin
which will be used by ath10k driver to identify coex support
of a hardware and notify wifi firmware the gpio pin number.
This pin number information is needed for the hardware QCA4019.

Subject: ath10k: Add support to read btcoex related data from DT

BTCOEX feature is not supported by all QCA4019 chipsets.
Since btcoex enabled by default in firmware, host needs to
enable COEX support depends on the hardware. Enabling it
by default in unsupported hardware will cause some
feature disabled in hardware.
This patch will read btcoex_support flag and
wlan priority gpio pin number from DT. Depends on the
btcoex_support flag value host will expose BTCOEX support
and wlan priority gpio pin number to target.

Testing:
	* Tested HW : QCA4019
	* Tested FW : 10.4-3.2.1.1-00017

Subject: ath11k: Silence clang -Wsometimes-uninitialized in
 ath11k_update_per_peer_stats_from_txcompl

Clang warns a few times (trimmed for brevity):

../drivers/net/wireless/ath/ath11k/debugfs_sta.c:185:7: warning:
variable 'rate_idx' is used uninitialized whenever 'if' condition is
false [-Wsometimes-uninitialized]

It is not wrong, rate_idx is only initialized in the first if block.
However, this is not necessarily an issue in practice because rate_idx
will only be used when initialized because
ath11k_accumulate_per_peer_tx_stats only uses rate_idx when flags is not
set to RATE_INFO_FLAGS_HE_MCS, RATE_INFO_FLAGS_VHT_MCS, or
RATE_INFO_FLAGS_MCS. Still, it is not good to stick uninitialized values
into another function so initialize it to zero to prevent any issues
down the line.

We will start using ieee80211_tx_status_ext() so we do not need to track
tx rates inside a struct ieee80211_tx_info. It is currently not possible
to populate that struct with HE rate info anyhow.

Subject: ath11k: fix rcu lock protect in peer assoc confirmation

ath11k_mac_get_ar_by_vdev_id() get protected under rcu lock
and unlock. peer association confirmation event get used this API
without rcu protection, so corrected it.

Subject: ath11k: fix warn-on in disassociation

In multi AP VAP scenario, when user bring down the interfaces. mac80211 mark
the interface down for the duplicated VAP and removed from the
local->interfaces list. ath11k_mac_get_arvif() is dependent on
ieee80211_iterate_active_interfaces_atomic() API to find the vdev id
in a given radio. In disassociation path, ath11k_mac_get_arvif() not
able to find the given vdev id since that VAP is removed from the
local->interfaces list. since sta_state callback throws error, mac80211 log
the below WARN_ON_ONCE message.

Fixed it by storing the allocated_vdev_map in each radio structure to maintain
the created vdev id bits. so that we can directly mask this against the given
vdev_id to find out the ar from the vdev_id.

Subject: ath11k: fix parsing PPDU_CTRL type in pktlog

PPDU_CTRL type is missing in current pktlog dumps.
PPDU_CTRL is sent on CE5 with len 2560 bytes, current
driver ignores the payload len greter than 2048.
PPDU_CTRL of 2560 bytes is sent in two fragments of len 2028
and 532 bytes, but firmware reports pkt header has length as 2560
for both of the fragments.

Subject: ath10k: avoid consecutive OTP download to reduce boot time

Currently, OTP is downloaded twice in case of "pre-cal-dt"
and "pre-cal-file" to fetch the board ID and takes around
~2 sec more boot uptime.

First OTP download happens in "ath10k_core_probe_fw" and
second in ath10k_core_start. First boot does not need OTP
download in core start when valid board id acquired.

The second OTP download is required upon core stop/start.

This patch skips the OTP download when first OTP download
has acquired a valid board id. This patch also marks board
id invalid in "ath10k_core_stop", which will force the OTP
download in ath10k_core_start and fetches valid board id.

Tested HW: QCA9984
Tested FW: 10.4-3.6-00104

Subject: ath10k: start recovery process when read int status fail for sdio

When running simulate crash stress test, it happened
"failed to read from address 0x800: -110".

Test steps:
1. Run command continuous
echo soft > /sys/kernel/debug/ieee80211/phy0/ath10k/simulate_fw_crash

2. error happened and it did not begin recovery for long time.
[74377.334846] ath10k_sdio mmc1:0001:1: simulating soft firmware crash
[74378.378217] ath10k_sdio mmc1:0001:1: failed to read from address 0x800: -110
[74378.378371] ath10k_sdio mmc1:0001:1: failed to process pending SDIO interrupts: -110

It has sdio errors since it can not read MBOX_HOST_INT_STATUS_ADDRESS,
then it has to do recovery process to recovery ath10k.

Tested with QCA6174 SDIO with firmware WLAN.RMH.4.4.1-00042.

Subject: ath10k: use kzalloc to read for ath10k_sdio_hif_diag_read

When use command to read values, it crashed.

command:

For sdio chip, it need the memory which is kmalloc, if it is
vmalloc from ath10k_mem_value_read, then it have a memory error.
kzalloc of ath10k_sdio_hif_diag_read32 is the correct type, so
add kzalloc in ath10k_sdio_hif_diag_read to replace the buffer
which is vmalloc from ath10k_mem_value_read.

This patch only effect sdio chip.

Tested with QCA6174 SDIO with firmware WLAN.RMH.4.4.1-00029.

Subject: ath10k: fix unsupported chip reset debugs file write

Before this change, after writing "warm_hw_reset" debugfs file, host
will send chip reset command to FW even though FW do not support this
service getting a warning print.

Though there is no FW impact before this change, this patch restricts
chip reset command sent to FW only if FW advertises the support via WMI
service bit.

Removed the redundant check and ath10k_warn() print as well.

New version FW will report chip reset service bit to host. Host allow user
to trigger WLAN chip reset only when fw report this service bit.

For older NON-TLV FW, since it do not report chip reset service bit, host
will not send chip reset command. For older TLV FW, since it report chip
reset service bit, host will send chip reset command.

Tested HW:  QCA9984, WCN3990

QCA9984 FW version: WLAN.BL.3.9.0.2-00042-S-1

Subject: ath11k: config reorder queue for all tids during peer setup

Currently rx tid setup is happening for TID 0 and TID 16
during peer setup. And if other TID packets received for
the peer it will be redirected to rx error ring and not through
reo ring. And this rx tid configuration cannot be done
in the rx error ring path since it is a atomic context.
So moving the rx tid setup for all tids during the peer setup.
This is required to enable PN offload functionality to route
all packets through reo ring.

Subject: ath10k: fix not registering airtime of 11a station with WMM disable

The tid of 11a station with WMM disable reported by FW is 0x10 in
tx completion. The tid 16 is mapped to a NULL txq since buffer
MMPDU capbility is not supported. Then 11a station's airtime will
not be registered due to NULL txq check. As a results, airtime of
11a station keeps unchanged in debugfs system.

Mask the tid along with IEEE80211_QOS_CTL_TID_MASK to make it in
the valid range.

Subject: ath11k: add thermal cooling device support

Thermal cooling device support is added to control the temperature by
throttling the data transmission for the given duration. Throttling is
done by suspending all data tx queues by given percentage of time. The
thermal device allows user to configure duty cycle.

Throttling can be disabled by setting the duty cycle to 0. The cooling
device can be found under /sys/class/thermal/cooling_deviceX/.
Corresponding soft link to this device can be found under phy folder.

/sys/class/ieee80211/phy*/device/cooling_device.

To set duty cycle as 40%,

echo 40 >/sys/class/ieee80211/phy*/device/cooling_device/cur_state

Subject: ath11k: add thermal sensor device support

Temperature sensor generates electrical analog voltage from temperature
of each chain. The analog voltage is converted to digital value through
ADC. For reading temperature values fom user space, hw monitoring device
is used.

Whenever the user requests for current temperature, the driver sends WMI
command and wait for response. For reading temperature,

cat /sys/class/ieee80211/phy*/device/hwmon/hwmon2/temp1_input

Subject: ath5k: Add proper dependency for ATH5K_AHB

The CONFIG_ATH5K_AHB could be enabled on ATH25 system without enabling
ATH5K driver itself.  This does not make sense because CONFIG_ATH5K_AHB
controls object build within drivers/net/wireless/ath/ath5k/ so enabling
it without CONFIG_ATH5K brings nothing.

Add proper dependency to CONFIG_ATH5K_AHB.

Subject: ath9k: Handle txpower changes even when TPC is disabled

When TPC is disabled IEEE80211_CONF_CHANGE_POWER event can be handled to
reconfigure HW's maximum txpower.

This fixes 0dBm txpower setting when user attaches to an interface for
the first time with the following scenario:

ieee80211_do_open()
    ath9k_add_interface()
        ath9k_set_txpower() /* Set TX power with not yet initialized
                               sc->hw->conf.power_level */

    ieee80211_hw_config() /* Iniatilize sc->hw->conf.power_level and
                             raise IEEE80211_CONF_CHANGE_POWER */

    ath9k_config() /* IEEE80211_CONF_CHANGE_POWER is ignored */

This issue can be reproduced with the following:

  $ modprobe -r ath9k
  $ modprobe ath9k
  $ wpa_supplicant -i wlan0 -c /tmp/wpa.conf &
  $ iw dev /* Here TX power is either 0 or 3 depending on RF chain */
  $ killall wpa_supplicant
  $ iw dev /* TX power goes back to calibrated value and subsequent
              calls will be fine */

Subject: ath5k: Use scnprintf() for avoiding potential buffer overflow

Since snprintf() returns the would-be-output size instead of the
actual output size, the succeeding calls may go beyond the given
buffer limit.  Fix it by replacing with scnprintf().

Subject: qtnfmac: support WPA3 SAE in AP mode

Enable WPA3 SAE support in AP mode. Driver currently supports cards
that offload SAE authentication to userspace. So allow userspace
software to subscribe and to send AUTH frames. Besides, enable
AP mode support in external_auth cfg80211 callback.

Subject: qtnfmac: support WPA3 OWE in AP mode

Enable WPA3 OWE support in AP mode. Driver currently supports cards that
offload OWE processing to userspace. This patch adds all the required
tools for such offloading. Firmware requests OWE processing sending new
UPDATE_OWE event to driver, which uses cfg80211_update_owe_info_event to
notify userspace software. After OWE processing is completed, userspace
sends calculated IEs to firmware using update_owe_info cfg80211 callback.

Subject: qtnfmac: assign each wiphy to its own virtual platform device

Quantenna Pearl device exposes multiple (up to 3) radio interfaces under
single PCIe function. So far all the wiphy devices were attached to the
same pcie device. As a result, all different wireless network devices
were reported under the same sysfs directory for pcie device, e.g.:

$ ls  /sys/class/net/wlan0/device/net/
  wlan0 wlan1

It turns out that such behavior may confuse various users of wireless
subsystem. For instance, it turned out to be the case for:
- Linux init systems, e.g. for renaming based on parent device
- OpenWRT configuration scripts

Suggested solution is to add an intermediate virtual platform device
for each radio interface.

Firmware supports only STA as primary interface in repeater mode.
Since the only meaningful usage of AP + STA interface combination
is repeater, reject such combination with AP as primary interface.

Subject: mwifiex: set needed_headroom, not hard_header_len

hard_header_len provides limitations for things like AF_PACKET, such
that we don't allow transmitting packets smaller than this.

needed_headroom provides a suggested minimum headroom for SKBs, so that
we can trivally add our headers to the front.

The latter is the correct field to use in this case, while the former
mostly just prevents sending small AF_PACKET frames.

In any case, mwifiex already does its own bounce buffering [1] if we
don't have enough headroom, so hints (not hard limits) are all that are
needed.

This is the essentially the same bug (and fix) that brcmfmac had, fixed
in commit cb39288fd6bb ("brcmfmac: use ndev->needed_headroom to reserve
additional header space").

[1] mwifiex_hard_start_xmit():
	if (skb_headroom(skb) < MWIFIEX_MIN_DATA_HEADER_LEN) {
	[...]
		/* Insufficient skb headroom - allocate a new skb */

Subject: libertas: Use new structure for SPI transfer delays

In a recent change to the SPI subsystem [1], a new `delay` struct was added
to replace the `delay_usecs`. This change replaces the current
`delay_usecs` with `delay` for this driver.

The `spi_transfer_delay_exec()` function [in the SPI framework] makes sure
that both `delay_usecs` & `delay` are used (in this order to preserve
backwards compatibility).

[1] commit bebcfd272df6 ("spi: introduce `delay` field for
`spi_transfer` + spi_transfer_delay_exec()")

Subject: prism54: Use scnprintf() for avoiding potential buffer overflow

Since snprintf() returns the would-be-output size instead of the
actual output size, the succeeding calls may go beyond the given
buffer limit.  Fix it by replacing with scnprintf().

Subject: mt76: mt76u: rely only on data buffer for usb control messagges

Starting from commit 'a6bfb6d13f33 ("mt76: usb: use max packet length
for m76u_copy")' reg_val does not share memory with usb data buffer.
On non-coherent devices this approach can corrupt data pointer since data
and reg_val share the same cache-line, resulting in the following crash:

Subject: mt76: mt7603: add upper limit for dynamic sensitivity minimum receive

If the minimum power is raised too much, it can make it impossible for weaker
clients to connect, and there are some scenarios where the false detects will
not go down no matter how much the sensitivity is adjusted.
Fixes connectivity issues in some rare cases

Subject: mt76: mt7615: fix monitor injection of beacon frames

When injecting beacon frames via monitor interface, they must not be sent to
the beacon hardware queue, because they don't follow normal hardware beacon tx
rules.
Fix sending them by adding a flag to mt7615_mac_write_txwi that selects the
beacon queue for tx, and use it only from mt7615_mcu_set_bcn.

Subject: mt76: always init to 0 mcu messages

Always initialize to 0 mcu messages since if they are not propely
configured they could hang the firmware.

Subject: mt76: mt7615: introduce mt7615_mcu_send_message routine

Introduce mt7615_mcu_send_message routine in order to allocate mcu skb
out of mcu sending routine. This approach is useful when the mcu
message is complicated and it is convenient to rely on skb buffer API

Subject: mt76: mt7615: add mt7615_mcu_ops data structure

Introduce mt7615_mcu_ops data structure in order to support multiple
mcu ops API.
Move mt7615_mcu_set_{tx,rx}_ba to mt7615_mcu_ops differentiating between
fw v1 and v2. This is a preliminary patch to properly support mt7663e
firmware.
Rework utility routines to rely on skb APIs for msg parsing

Subject: mt76: mt7615: move mt7615_mcu_set_bmc to mt7615_mcu_ops

Move mt7615_mcu_set_bmc for fw version 1 and version 2 in
mt7615_mcu_ops data structure. This is a preliminary patch
to properly support mt7663e firmware.
Rework utility routines to rely on skb APIs for msg parsing

From b4985ff18c829ff875bbbec92b75c656496d8f24 Mon Sep 17 00:00:00 2001
From: Lorenzo Bianconi <lorenzo@kernel.org>
Date: Tue, 17 Mar 2020 17:41:16 +0100
Subject: mt76: mt7615: move mt7615_mcu_set_sta in mt7615_mcu_ops

Move mt7615_mcu_set_sta for fw version 1 and version 2 in mt7615_mcu_ops
data structure. This is a preliminary patch to properly support mt7663e
firmware.
Rework utility routines to rely on skb APIs for msg parsing

From 062c3699b9fde3ac9e3e5c2dadab1cd8bb65bbb6 Mon Sep 17 00:00:00 2001
From: Lorenzo Bianconi <lorenzo@kernel.org>
Date: Tue, 17 Mar 2020 17:41:19 +0100
Subject: mt76: mt7615: move more mcu commands in mt7615_mcu_ops data structure

Move mt7615_mcu_set_beacon_offload, mt7615_mcu_set_dev and
mt7615_mcu_set_bss routine in mt7615_mcu_ops data structure.
This is a preliminary patch to support mt7663 firmware

Subject: mt76: mt7615: introduce MCU_FW_PREFIX for fw mcu commands

Currently fw commands rely on negative cmds since they need different
mcu msg metadata. Extend this approach introducing MCU_FW_PREFIX.
This is a preliminary patch to support new mt7663e firmware commands

In order to reuse mt7615 code adding support for mt7663e driver,
introduce mt7615e_reg_map since mt7663e and mt7615 rely on a
different base registers definitions.

Subject: mt76: mt7615: introduce mt7615_eeprom_parse_hw_band_cap routine

Introduce mt7615_eeprom_parse_hw_band_cap routine in order to configure
supported band for mt7663e and mt7622 devices since they do not rely on
eeprom data to enable 2GHz/5GHz bands

Introduce mcu uni command type. Uni commands rely on a stripped verions
of mt7615_mcu_txd data strutture. Split mt7615_mcu_txd_common and
mt7615_mcu_txd. Uni commands will be use by mt7663e driver

Subject: iwlwifi: move the remaining 0x2526 configs to the new table

Now that we have the strings separate from the rest, we can move the
remaining 0x2526 devices to the new table in preparation to reuse the
configs.

Subject: iwlwifi: combine 9260 cfgs that only change names

All the 0x2526 devices are now in the new table, so we can start
reusing configurations and adding the strings independently to all of
them, reusing them when possible.

Subject: iwlwifi: add mac/rf types and 160MHz to the device tables

Add MAC ID, RF ID and the bit that tells us whether the device can
handle 160MHz bandwidth to the device struct.

This allows us to chose the correct structure and string depending on
these parameters.  Do so for all the 0x2526 devices we already moved
to the new table.

Subject: iwlwifi: add GNSS differentiation to the device tables

Devices that also include a GNSS module have different names, so add a
new device option to differentiate them, according to the values we
have in the modules section of the subsystem device ID.

Additionally, convert the two applicable devices to use this value
instead of hardcoded subsystem IDs.

Subject: iwlwifi: add Pu/PnJ/Th device values to differentiate them

Pu, PnJ and Th devices have different combinations of PCI ID, MAC ID
and RF IDs.  Use these to differentiate them and choose the correct
configuration.

This also includes a change from using soc cfg's for 0x2526
devices (PnJ/Th), which was incorrect.

Subject: iwlwifi: map 9461 and 9462 using RF type and RF ID

These devices can be differentiated depending on the RF type and RF
ID.  Change them to use these instead of relying on the subsystem
device IDs.

This also fixes some names that were not including 160MHz (as they
should).

Subject: iwlwifi: move TH1 devices to the new table

TH1 devices can now be fully differentiated by using the device
parameters we have (particularly the RF_TYPE).  Start using these
parameters instead of hardcoding to specific subsystem device IDs.

This also fixes the name of one of the TH1 devices that was
erroneously using the 9260 struct and renames 9160 to 9162.

Subject: iwlwifi: convert the 9260-1x1 device to use the new parameters

The 9260-1x1 device can be differentiated using the PCI device ID.
There is a single occurrence of this device, so continue relying on
the device and subsystem device IDs.

The name of this device was incorrect, so add a new string
specifically for it.

Subject: iwlwifi: move pu devices to new table

All the pu devices can now be differentiated using the new
parameters, so move them all to the new tables accordingly.

This also includes removal of a few deprecated IDs and redundant cfg
structs.

These entries are decided at runtime using the new parameters now, so
they are not needed in the macro that is reused in the configs.

Subject: wireless: realtek: Replace zero-length array with flexible-array
 member

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:

struct foo {
        int stuff;
        struct boo array[];
};

By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.

Also, notice that, dynamic memory allocations won't be affected by
this change:

"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]

This issue was found with the help of Coccinelle.

Subject: wireless: ti: Replace zero-length array with flexible-array member

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:

struct foo {
        int stuff;
        struct boo array[];
};

By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.

Also, notice that, dynamic memory allocations won't be affected by
this change:

"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]

This issue was found with the help of Coccinelle.

Subject: wireless: marvell: Replace zero-length array with flexible-array
 member

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:

struct foo {
        int stuff;
        struct boo array[];
};

By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.

Also, notice that, dynamic memory allocations won't be affected by
this change:

"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]

This issue was found with the help of Coccinelle.

Subject: atmel: at76c50x: Replace zero-length array with flexible-array member

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:

struct foo {
        int stuff;
        struct boo array[];
};

By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.

Also, notice that, dynamic memory allocations won't be affected by
this change:

"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]

This issue was found with the help of Coccinelle.

Subject: rtw88: don't hold all IRQs disabled for PS operations

This driver generally only needs to ensure that
(a) it doesn't try to process TX interrupts at the same time as
    power-save operations (and similar)
(b) the device interrupt gets disabled while we're still handling the
    last set of interrupts

For (a), all the operations (e.g., PS transitions, packet handling)
happens in non-atomic contexts (e.g., threaded IRQ).

For (b), we only need mutual exclusion for brief sections (i.e., while
we're actually manipulating the interrupt mask/status).

So, we can introduce a separate lock for handling (b), disabling IRQs
while we do it. For (a), we can demote the locking to BH only, now that
(b) (the only steps done in atomic context) and that has its own lock.

This helps reduce the amount of time this driver spends with IRQs off.
Notably, transitioning out of power-save modes can take >3 milliseconds,
and this transition is done under the protection of 'irq_lock'.

Subject: rtw88: extract alloc rsvd_page and h2c skb routines

Extract skb allocation routines for rsvd_page and h2c.
These routines should also be used by USB and SDIO.

This should not change the logic at all.
memset() for pkt_info is unnecessary, just declare as {0}.
Also skb_put()/memcpy() can be replaced by skb_put_data().

Subject: rtw88: associate reserved pages with each vif

Each device has only one reserved page shared with all of the
vifs, so it seems not reasonable to pass vif as one of the
arguments to rtw_fw_download_rsvd_page(). If driver is going
to run more than one vif, the content of reserved page could
not be built for all of the vifs.

To fix it, let each vif maintain its own reserved page list,
and build the final reserved page to download to the firmware
from all of the vifs. Hence driver should add reserved pages
to each vif according to the vif->type when adding the vif.

For station mode, add reserved page with rtw_add_rsvd_page_sta().
If the station mode is going to suspend in PNO (net-detect)
mode, remove the reserved pages used for normal mode, and add
new one for wowlan mode with rtw_add_rsvd_page_pno().

For beacon mode, only beacon is required to be added using
rtw_add_rsvd_page_bcn().

This would make the code flow simpler as we don't need to
add reserved pages when vif is running, just add/remove them
when ieee80211_ops::[add|remove]_interface.

When driver is going to download the reserved page, it will
collect pages from all of the vifs, this list is maintained
by rtwdev, with build_list as the pages' member. That way, we
can still build a list of reserved pages to be downloaded.
Also we can get the location of the pages from the list that
is maintained by rtwdev.

The biggest problem is that the first page should always be
beacon, if other type of reserved page is put in the first
page, the tx descriptor and offset could be wrong.
But station mode vif does not add beacon into its list, so
we need to add a dummy page in front of the list, to make
sure other pages will not be put in the first page. As the
dummy page is allocated when building the list, we must free
it before building a new list of reserved pages to firmware.

From: Yan-Hsuan Chuang <yhchuang@realtek.com>
Date: Thu, 12 Mar 2020 16:08:51 +0800
Subject: rtw88: pci: define a mask for TX/RX BD indexes

Add a macro TRX_BD_IDX_MASK for access the TX/RX BD indexes.

The hardware has only 12 bits for TX/RX BD indexes, we should not
initialize a TX/RX ring or access the TX/RX BD index with a length
that is larger than TRX_BD_IDX_MASK.

Subject: rtw88: kick off TX packets once for higher efficiency

Driver used to kick off every TX packets, that will waste some
time while we can do better to kick off the TX packets once after
they are all prepared to be transmitted.

For PCI, it uses DMA engine to transfer the SKBs to the device,
and the transition of the state of the DMA engine could be a cost.
Driver can save some time to kick off multiple SKBs once so that
the DMA engine will have only one transition.

So, split rtw_hci_ops::tx() to rtw_hci_ops::tx_write() and
rtw_hci_ops::tx_kick_off() to explicitly kick the SKBs off after
they are written to the prepared buffer. For packets come from
ieee80211_ops::tx(), write one and then kick it off immediately.
For packets queued in TX queue, which come from
ieee80211_ops::wake_tx_queue(), we can dequeue them, write them
to the buffer, and then kick them off together.

Subject: rtw88: 8822c: config RF table path B before path A

After MAC switched power, the hardware's RF registers will have
its default value, but the default value for path B is incorrect.
So, load RF path B first, to decrease the period between MAC on
and RF path B config.

By test, if we load path A first, then there's ~300ms that the
path B is incorrect, it could lead to BT coex's A2DP glitch.
But if we configure path B first, there will only have ~3ms,
significantly lower possibility to have A2DP sound glitch.
