Late reset controller changes for v5.0
This adds missing deassert functionality to the ARC HSDK reset driver,
fixes some indentation and grammar issues in the kernel docs, adds a
helper to count the number of resets on a device for the non-DT case

Commit 49e54187ae0b ("ata: libahci_platform: comply to PHY framework") uses
the PHY_MODE_SATA, but that enum had not yet been added. This caused a
build failure for me, with today's linux.git.
Also, there is a potentially conflicting (mis-named) PHY_MODE_SATA, hiding
in the Marvell Berlin SATA PHY driver.
Fix the build by:
1) Renaming Marvell's defined value to a more scoped name,
in order to avoid any potential conflicts: PHY_BERLIN_MODE_SATA.
2) Adding the missing enum, which was going to be added anyway as part
of [1].

Pull dma_zalloc_coherent() removal from Christoph Hellwig:
"We've always had a weird situation around dma_zalloc_coherent. To
safely support mapping the allocations to userspace major
architectures like x86 and arm have always zeroed allocations from
dma_alloc_coherent, but a couple other architectures were missing that
zeroing either always or in corner cases.
Then later we grew anothe dma_zalloc_coherent interface to explicitly
request zeroing, but that just added __GFP_ZERO to the allocation
flags, which for some allocators that didn't end up using the page
allocator ended up being a no-op and still not zeroing the
allocations.
So for this merge window I fixed up all remaining architectures to
zero the memory in dma_alloc_coherent, and made dma_zalloc_coherent a
no-op wrapper around dma_alloc_coherent, which fixes all of the above
issues.
dma_zalloc_coherent is now pointless and can go away, and Luis helped
me writing a cocchinelle script and patch series to kill it, which I
think we should apply now just after -rc1 to finally settle these
issue"

When allocating memory pages for context memory, if the last page table
should be fully populated, the current code will set nr_pages to 0 when
calling bnxt_alloc_ctx_mem_blk(). This will cause the last page table
to be completely blank and causing some RDMA failures.
Fix it by setting the last page table's nr_pages to the remainder only
if it is non-zero.

One of the more common cases of allocation size calculations is finding the
size of a structure that has a zero-sized array at the end, along with memory
for some number of elements for that array. For example:
struct foo {
int stuff;
void *entry[];
};
instance = kzalloc(sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL);
Instead of leaving these open-coded and prone to type mistakes, we can now
use the new struct_size() helper:
instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL);
This code was detected with the help of Coccinelle.

The vsock core only supports 32bit CID, but the Virtio-vsock spec define
CID (dst_cid and src_cid) as u64 and the upper 32bits is reserved as
zero. This inconsistency causes one bug in vhost vsock driver. The
scenarios is:
0. A hash table (vhost_vsock_hash) is used to map an CID to a vsock
object. And hash_min() is used to compute the hash key. hash_min() is
defined as:
(sizeof(val) <= 4 ? hash_32(val, bits) : hash_long(val, bits)).
That means the hash algorithm has dependency on the size of macro
argument 'val'.
0. In function vhost_vsock_set_cid(), a 64bit CID is passed to
hash_min() to compute the hash key when inserting a vsock object into
the hash table.
0. In function vhost_vsock_get(), a 32bit CID is passed to hash_min()
to compute the hash key when looking up a vsock for an CID.
Because the different size of the CID, hash_min() returns different hash
key, thus fails to look up the vsock object for an CID.
To fix this bug, we keep CID as u64 in the IOCTLs and virtio message
headers, but explicitly convert u64 to u32 when deal with the hash table
and vsock core.

Currently, TX is given a budget which is consumed by stmmac_tx_clean()
and stmmac_rx() is given the remaining non-consumed budget.
This is wrong and in case we are sending a large number of packets this
can starve RX because remaining budget will be low.
Let's give always the same budget for RX and TX clean.
While at it, check if we missed any interrupts while we were in NAPI
callback by looking at DMA interrupt status.

A feature has been added in the libahci driver: the possibility to set

automatically. Make use of this feature to make suspend to RAM work

A3700 comphy initialization is done in the firmware (TF-A). Looking at
the SATA PHY initialization routine, there is a comment about "vendor
specific" registers. Two registers are mentioned. They are not
initialized there in the firmware because they are AHCI related, while
the firmware at this location does only PHY configuration. The
solution to avoid doing such initialization is relying on U-Boot.
While this work at boot time, U-Boot is definitely not going to run
during a resume after suspending to RAM.
Two possible solutions were considered:
* Fixing the firmware.
* Fixing the kernel driver.
The first solution would take ages to propagate, while the second
solution is easy to implement as the driver as been a little bit
reworked to prepare for such platform configuration. Hence, this patch
adds an Armada 3700 configuration function to set these two registers
both at boot time (in the probe) and after a suspend (in the resume
path).

At the beginning, only Armada 38x SoCs where supported by the
ahci_mvebu.c driver. Commit 15d3ce7b63bd ("ata: ahci_mvebu: add
support for Armada 3700 variant") introduced Armada 3700 support. As
opposed to Armada 38x SoCs, the 3700 variants do not have to configure
mbus and the regret option. This patch took care of avoiding such
configuration when not needed in the probe function, but failed to do
the same in the resume path. While doing so looks harmless by
experience, let's clean the driver logic and avoid doing this useless
configuration with Armada 3700 SoCs.
Because the logic is very similar between these two places, it has
been decided to factorize this code and put it in a "Armada 38x
configuration function". This function is part of a new
(per-compatible) platform data structure, so that the addition of such
configuration function for Armada 3700 will be eased.

commit 3cbd6a6ca81c ("ARM: mvebu: Add standby support")

Current implementation of the libahci does not take into account the
new PHY framework. Correct the situation by adding a call to
phy_set_mode() before phy_power_on().
PHYs should also be handled at suspend/resume time. For this, call
ahci_platform_enable/disable_phys() at suspend/resume_host() time. These
calls are guarded by a HFLAG (AHCI_HFLAG_SUSPEND_PHYS) that the user of
the libahci driver must set manually in hpriv->flags at probe time. This
is to avoid breaking users that have not been tested with this change.

Try to get reference for ldisc during tty_reopen().
If ldisc present, we don't need to do tty_ldisc_reinit() and lock the
write side for line discipline semaphore.
Effectively, it optimizes fast-path for tty_reopen(), but more
importantly it won't interrupt ongoing IO on the tty as no ldisc change
is needed.
Fixes user-visible issue when tty_reopen() interrupted login process for
user with a long password, observed and reported by Lukas.
Fixes: c96cf923a98d ("tty: Don't block on IO when ldisc change is pending")
Fixes: 83d817f41070 ("tty: Hold tty_ldisc_lock() during tty_reopen()")

Since commit 89a5e15bcba87d ("gpio/mmc/of: Respect polarity in the device
tree") gpiolib-of parses the "cd-gpios" property and flips the polarity
if "cd-inverted" is also set. This results in the "cd-inverted" property
being evaluated twice, which effectively makes it a no-op:
- first in drivers/gpio/gpiolib-of.c (of_xlate_and_get_gpiod_flags) when
setting up the CD GPIO
- then again in drivers/mmc/core/slot-gpio.c (mmc_gpio_get_cd) when
reading the CD GPIO value at runtime
On boards which are using device-tree with the "cd-inverted" property
being set any inserted card are not detected anymore. This is due to the
MMC core treating the CD GPIO with the wrong polarity.
Disable "override_cd_active_level" for the card detection GPIO which is
parsed using mmc_of_parse. This fixes SD card detection on the boards
which are currently using the "cd-inverted" device-tree property (tested
on Meson8b Odroid-C1 and Meson8b EC-100).
This does not remove the CD GPIO inversion logic from the MMC core
because there's at least one driver (sdhci-pci-core for Intel BayTrail
based boards) which still passes "override_cd_active_level = true" to
mmc_gpiod_request_cd(). Due to lack of hardware for testing this is left
untouched.
In the future the GPIO inversion logic for both, card and read-only
detection can be removed once no driver is using it anymore.

When executed for a PCI_ROOT_COMPLEX type, iort_match_node_callback()
expects the opaque pointer argument to be a PCI bus device. At the
moment rc_dma_get_range() passes the PCI endpoint instead of the bus,
and we've been lucky to have pci_domain_nr(ptr) return 0 instead of
crashing. Pass the bus device to iort_scan_node().

If adapter->retries is set to a minus value from user space via ioctl,
it will make __i2c_transfer and __i2c_smbus_xfer skip the calling to
adapter->algo->master_xfer and adapter->algo->smbus_xfer that is
registered by the underlying bus drivers, and return value 0 to all the
callers. The bus driver will never be accessed anymore by all users,
besides, the users may still get successful return value without any
error or information log print out.
If adapter->timeout is set to minus value from user space via ioctl,
it will make the retrying loop in __i2c_transfer and __i2c_smbus_xfer
always break after the the first try, due to the time_after always
returns true.

maybe other boards using this generic driver are affected
v2:
optimization:
- phy_set_max_speed() is only needed if you want to reduce the
max speed, typically if the PHY supports 1Gbps but the MAC
supports 100Mbps only.
- The pause parameters are autonegotiated. Except you have a specific
need you normally don't need to manually fiddle with this.
- phy_start_aneg() is called implicitly by the phylib state machine,
you shouldn't call it manually except you have a good excuse.
- netif_carrier_on/netif_carrier_off in mtk_phy_link_adjust() isn't
needed. It's done by phy_link_change() in phylib.
