Parsing firmware error message from original version and v1 reports to
show up exception counter of commands from firmware in debug message.
Then, we can make sure exchange commands are correct totally.
In the later version Wi-Fi firmware(v1), the report format was changed.
With this update, we can yield correct report from proper struct.

On Device Tree platforms, it is customary to be able to set the MAC
address via the Device Tree, as it is often stored in system firmware.
This is particularly relevant for Apple ARM64 platforms, where this
information comes from system configuration and passed through by the
bootloader into the DT.
Implement support for this by fetching the platform MAC address and
adding or replacing the macaddr= property in nvram. This becomes the
dongle's default MAC address.
On platforms with an SROM MAC address, this overrides it. On platforms
without one, such as Apple ARM64 devices, this is required for the
firmware to boot (it will fail if it does not have a valid MAC at all).

On Apple platforms, firmware selection uses the following elements:
Property Example Source
============== ======= ========================
* Chip name 4378 Device ID
* Chip revision B1 OTP
* Platform shikoku DT (ARM64) or ACPI (x86)
* Module type RASP OTP
* Module vendor m OTP
* Module version 6.11 OTP
* Antenna SKU X3 DT (ARM64) or ACPI (x86)
In macOS, these firmwares are stored using filenames in this format
under /usr/share/firmware/wifi:
C-4378__s-B1/P-shikoku-X3_M-RASP_V-m__m-6.11.txt
To prepare firmwares for Linux, we rename these to a scheme following
the existing brcmfmac convention:
brcmfmac<chip><lower(rev)>-pcie.apple,<platform>-<mod_type>-\
<mod_vendor>-<mod_version>-<antenna_sku>.txt
The NVRAM uses all the components, while the firmware and CLM blob only
use the chip/revision/platform/antenna_sku:
brcmfmac<chip><lower(rev)>-pcie.apple,<platform>-<antenna_sku>.bin
e.g.
brcm/brcmfmac4378b1-pcie.apple,shikoku-RASP-m-6.11-X3.txt
brcm/brcmfmac4378b1-pcie.apple,shikoku-X3.bin
In addition, since there are over 1000 files in total, many of which are
symlinks or outright duplicates, we deduplicate and prune the firmware
tree to reduce firmware filenames to fewer dimensions. For example, the
shikoku platform (MacBook Air M1 2020) simplifies to just 4 files:
brcm/brcmfmac4378b1-pcie.apple,shikoku.clm_blob
brcm/brcmfmac4378b1-pcie.apple,shikoku.bin
brcm/brcmfmac4378b1-pcie.apple,shikoku-RASP-m.txt
brcm/brcmfmac4378b1-pcie.apple,shikoku-RASP-u.txt
This reduces the total file count to around 170, of which 75 are
symlinks and 95 are regular files: 7 firmware blobs, 27 CLM blobs, and
61 NVRAM config files. We also slightly process NVRAM files to correct
some formatting issues.
To handle this, the driver must try the following path formats when
looking for firmware files:
brcm/brcmfmac4378b1-pcie.apple,shikoku-RASP-m-6.11-X3.txt
brcm/brcmfmac4378b1-pcie.apple,shikoku-RASP-m-6.11.txt
brcm/brcmfmac4378b1-pcie.apple,shikoku-RASP-m.txt
brcm/brcmfmac4378b1-pcie.apple,shikoku-RASP.txt
brcm/brcmfmac4378b1-pcie.apple,shikoku-X3.txt *
brcm/brcmfmac4378b1-pcie.apple,shikoku.txt
* Not relevant for NVRAM, only for firmware/CLM.
The chip revision nominally comes from OTP on Apple platforms, but it
can be mapped to the PCI revision number, so we ignore the OTP revision
and continue to use the existing PCI revision mechanism to identify chip
revisions, as the driver already does for other chips. Unfortunately,
the mapping is not consistent between different chip types, so this has
to be determined experimentally.

On Apple ARM64 platforms, firmware selection requires two properties
that come from system firmware: the module-instance (aka "island", a
codename representing a given hardware platform) and the antenna-sku.
We map Apple's module codenames to board_types in the form
"apple,<module-instance>".
The mapped board_type is added to the DTS file in that form, while the
antenna-sku is forwarded by our bootloader from the Apple Device Tree
into the FDT. Grab them from the DT so firmware selection can use
them.

Apple platforms have firmware and config files identified with multiple
dimensions. We want to be able to find the most specific firmware
available for any given platform, progressively trying more general
firmwares.
To do this, first add support for passing in multiple board_types,
which will be tried in sequence.
Since this will cause more log spam due to missing firmwares, also
switch the secondary firmware fecthes to use the _nowarn variant, which
will not log if the firmware is not found.

This binding is currently used for SDIO devices, but these chips are
also used as PCIe devices on DT platforms and may be represented in the
DT. Re-use the existing binding and add chip compatibles used by Apple
T2 and M1 platforms (the T2 ones are not known to be used in DT
platforms, but we might as well document them).
Then, add properties required for firmware selection and calibration on
M1 machines.

The test enables single-step execution from userspace, and check if the
exit to userspace occurs for each instruction that is stepped.

sufficient to always reproduce the problem that the previous patch fixes
on an Ampere Altra machine.

While userspace enables single-step, if the Software Step state at the
last guest exit was "Active-pending", clear PSTATE.SS on guest entry
to restore the state.
Currently, KVM sets PSTATE.SS to 1 on every guest entry while userspace
enables single-step for the vCPU (with KVM_GUESTDBG_SINGLESTEP).
It means KVM always makes the vCPU's Software Step state
"Active-not-pending" on the guest entry, which lets the VCPU perform
single-step (then Software Step exception is taken). This could cause
extra single-step (without returning to userspace) if the Software Step
state at the last guest exit was "Active-pending" (i.e. the last
exit was triggered by an asynchronous exception after the single-step
is performed, but before the Software Step exception is taken.
See "Figure D2-3 Software step state machine" and "D2.12.7 Behavior
in the active-pending state" in ARM DDI 0487I.a for more info about
this behavior).
Fix this by clearing PSTATE.SS on guest entry if the Software Step state
at the last exit was "Active-pending" so that KVM restore the state (and
the exception is taken before further single-step is performed).

Preserve the PSTATE.SS value for the guest while userspace enables
single-step (i.e. while KVM manipulates the PSTATE.SS) for the vCPU.
Currently, while userspace enables single-step for the vCPU
(with KVM_GUESTDBG_SINGLESTEP), KVM sets PSTATE.SS to 1 on every
guest entry, not saving its original value.
When userspace disables single-step, KVM doesn't restore the original
value for the subsequent guest entry (use the current value instead).
Exception return instructions copy PSTATE.SS from SPSR_ELx.SS
only in certain cases when single-step is enabled (and set it to 0
in other cases). So, the value matters only when the guest enables
single-step (and when the guest's Software step state isn't affected
by single-step enabled by userspace, practically), though.
Fix this by preserving the original PSTATE.SS value while userspace
enables single-step, and restoring the value once it is disabled.
This fix modifies the behavior of GET_ONE_REG/SET_ONE_REG for the
PSTATE.SS while single-step is enabled by userspace.
Presently, GET_ONE_REG/SET_ONE_REG gets/sets the current PSTATE.SS
value, which KVM will override on the next guest entry (i.e. the
value userspace gets/sets is not used for the next guest entry).
With this patch, GET_ONE_REG/SET_ONE_REG will get/set the guest's
preserved value, which KVM will preserve and try to restore after
single-step is disabled.

Commit b6d09f780761 ("pinctrl: nomadik: Drop U8540/9540 support") removes
the DB8540 pin controller driver and its config PINCTRL_DB8540.
There is some code left-over in the generic nomadik pinctrl driver, i.e.,
drivers/pinctrl/nomadik/pinctrl-nomadik.{ch}, that is still around for the
removed DB8540 pin controller driver.
Remove this remaining dead code.
This issue was discovered with ./scripts/checkkconfigsymbols.py.

The irq data passed to irc_chip handlers i the struct gpio_chip
and nothing else. We are just lucky that the nomadik chip
pointer is first in the struct. Use the proper dereferencing
and helpers.

There is an error check following the allocation of flash_buf that returns
without freeing flash_buf. It makes more sense to do the error check
before the allocation and the reordering eliminates the memory leak.

cros_ec_handle_event in the cros_ec driver can notify the PM of wake
events. When a device is suspended, cros_ec_handle_event will not check
MKBP events. Instead, received MKBP events are checked during resume by
cros_ec_report_events_during_suspend. But
cros_ec_report_events_during_suspend cannot notify the PM if received
events are wake events, causing wake events to not be reported if
received while the device is suspended.
Update cros_ec_report_events_during_suspend to notify the PM of wake
events during resume by calling pm_wakeup_event.

Some newer Allwinner SoCs contain internal LDOs managed by a register in
the system control MMIO space. Export this from the regmap in addtion to
the EMAC register.
Use generic names now that the regmap is no longer EMAC-specific.
