MT8188 and MT8195 are ARM platform SoCs with the same PCIe IP as MT8192.
Also add new clock name "peri_mem" since the MT8188 and MT8195 use clock
"peri_mem" instead of "top_133m".

Make it easy for liburing to integrate uapi header with the kernel.
Previously, when this header changes, the liburing side can't directly
copy this header file due to some small differences. Sync them.

The Gru-Bob board does not have a pull-up resistor on its
WLAN_HOST_WAKE# pin, but Kevin does. The production/vendor kernel
specified the pin configuration correctly as a pull-up, but this didn't
get ported correctly to upstream.
This means Bob's WLAN_HOST_WAKE# pin is floating, causing inconsistent
wakeup behavior.
Note that bt_host_wake_l has a similar dynamic, but apparently the
upstream choice was to redundantly configure both internal and external
pull-up on Kevin (see the "Kevin has an external pull up" comment in
rk3399-gru.dtsi). This doesn't cause any functional problem, although
it's perhaps wasteful.

It's pretty possible to have the spi_register_controller() method
returning -EPROBE_DEFER status in case, for instance, if the GPIOs used
for the CS implementation aren't ready to be requested due to the
corresponding platform devices still pending to be probed. Let's make sure
the DW SSI driver won't print error message in that case by calling the
dev_err_probe() function if the SPI-registration procedure exited with
a non-zero status.

This patch introduces the proper hw constraint for adjusting the

After the recently added new scmi_msg_dump traces, the general format of
the various other SCMI traces are not consistent.
As an example the full traces of a simple PERF_LEVEL_SET:
| cpufreq-set-276 scmi_xfer_begin: transfer_id=145 msg_id=7 protocol_id=19 seq=145 poll=0
| cpufreq-set-276 scmi_msg_dump: pt=13 t=CMND msg_id=07 seq=0091 s=0 pyld=000000008066ab13
| cpufreq-set-276 scmi_xfer_response_wait: transfer_id=145 msg_id=7 protocol_id=19 seq=145 tmo_ms=5000 poll=0
| <idle>-0 scmi_msg_dump: pt=13 t=RESP msg_id=07 seq=0091 s=0 pyld=
| <idle>-0 scmi_rx_done: transfer_id=145 msg_id=7 protocol_id=19 seq=145 msg_type=0
| cpufreq-set-276 scmi_xfer_end: transfer_id=145 msg_id=7 protocol_id=19 seq=145 status=0
... where the same information is being reported using different names
(protocol_id= vs pt=) and even worst different bases, which is hard to
read and to parse.
So let us unify them, using the same naming and ordering of the fields
(wherever possible) and moving all the protocol related fields to base-16
while keeping in base-10 timeouts, res_id and values, so that the new
traces would be like:
| cpufreq-set-274 scmi_xfer_begin: pt=13 msg_id=07 seq=0092 transfer_id=92 poll=0
| cpufreq-set-274 scmi_msg_dump: pt=13 t=CMND msg_id=07 seq=0092 s=0 pyld=000000008066ab13

SCMI Reset protocol specification allows the asynchronous reset request
only when an autonomous reset action is specified. Reset requests based
on explicit assert/deassert of signals should not be served
asynchronously.
Current implementation will instead issue an asynchronous request in any
case, as long as the reset domain had advertised to support asynchronous
resets.
Avoid requesting the asynchronous resets when the reset action is not
of the autonomous type, even if the target reset domain does, in general,
support the asynchronous requests.

Currently as part of handling a SME access trap we flush the SVE register
state. This is not needed and would corrupt register state if the task has
access to the SVE registers already. For non-streaming mode accesses the
required flushing will be done in the SVE access trap. For streaming
mode SVE register accesses the architecture guarantees that the register
state will be flushed when streaming mode is entered or exited so there is
no need for us to do so. Simply remove the register initialisation.

Currently when taking a SME access trap we allocate storage for the SVE
register state in order to be able to handle storage of streaming mode SVE.
Due to the original usage in a purely SVE context the SVE register state
allocation this also flushes the register state for SVE if storage was
already allocated but in the SME context this is not desirable. For a SME
access trap to be taken the task must not be in streaming mode so either
there already is SVE register state present for regular SVE mode which would
be corrupted or the task does not have TIF_SVE and the flush is redundant.
Fix this by adding a flag to sve_alloc() indicating if we are in a SVE
context and need to flush the state. Freshly allocated storage is always
zeroed either way.

When handling a signal delivered to a context with streaming mode enabled
we will disable streaming mode for the signal handler, when doing so we
should also flush the saved FPSIMD register state like exiting streaming
mode in the hardware would do so that if that state is reloaded we get the
same behaviour. Without this we will reload whatever the last FPSIMD state
that was saved for the task was.

The signal code has a limit of 64K on the size of a stack frame that it
will generate, if this limit is exceeded then a process will be killed if
it receives a signal. Unfortunately with the advent of SME this limit is
too small - the maximum possible size of the ZA register alone is 64K. This
is not an issue for practical systems at present but is easily seen using
virtual platforms.
Raise the limit to 256K, this is substantially more than could be used by
any current architecture extension.

Ard noticed that since we converted CTR_EL0 to automatic generation we have
been seeing errors on some systems handling the value of cache_type_cwg()
such as
CPU features: No Cache Writeback Granule information, assuming 128
This is because the manual definition of CTR_EL0_CWG_MASK was done without
a shift while our convention is to define the mask after shifting. This
means that the user in cache_type_cwg() was broken as it was written for
the manually written shift then mask. Fix this by converting to use
SYS_FIELD_GET().
The only other field where the _MASK for this register is used is IminLine
which is at offset 0 so unaffected.

Though acpi_find_last_cache_level() always returned signed value and the
document states it will return any errors caused by lack of a PPTT table,
it never returned negative values before.
Commit 0c80f9e165f8 ("ACPI: PPTT: Leave the table mapped for the runtime usage")
however changed it by returning -ENOENT if no PPTT was found. The value
returned from acpi_find_last_cache_level() is then assigned to unsigned
fw_level.
It will result in the number of cache leaves calculated incorrectly as
a huge value which will then cause the following warning from __alloc_pages
as the order would be great than MAX_ORDER because of incorrect and huge
cache leaves value.

The AMU counter AMEVCNTR01 (constant counter) should increment at the same
rate as the system counter. On affected Cortex-A510 cores, AMEVCNTR01
increments incorrectly giving a significantly higher output value. This
results in inaccurate task scheduler utilization tracking and incorrect
feedback on CPU frequency.
Work around this problem by returning 0 when reading the affected counter
in key locations that results in disabling all users of this counter from
using it either for frequency invariance or as FFH reference counter. This
effect is the same to firmware disabling affected counters.
Details on how the two features are affected by this erratum:
- AMU counters will not be used for frequency invariance for affected
CPUs and CPUs in the same cpufreq policy. AMUs can still be used for
frequency invariance for unaffected CPUs in the system. Although
unlikely, if no alternative method can be found to support frequency
invariance for affected CPUs (cpufreq based or solution based on
platform counters) frequency invariance will be disabled. Please check
the chapter on frequency invariance at
Documentation/scheduler/sched-capacity.rst for details of its effect.
- Given that FFH can be used to fetch either the core or constant counter
values, restrictions are lifted regarding any of these counters
returning a valid (!0) value. Therefore FFH is considered supported
if there is a least one CPU that support AMUs, independent of any
counters being disabled or affected by this erratum. Clarifying
comments are now added to the cpc_ffh_supported(), cpu_read_constcnt()
and cpu_read_corecnt() functions.
The above is achieved through adding a new erratum: ARM64_ERRATUM_2457168.

On arm64, "rodata=full" has been suppored (but not documented) since
commit:
c55191e96caa9d78 ("arm64: mm: apply r/o permissions of VM areas to its linear alias as well")
As it's necessary to determine the rodata configuration early during
boot, arm64 has an early_param() handler for this, whereas init/main.c
has a __setup() handler which is run later.
Unfortunately, this split meant that since commit:
f9a40b0890658330 ("init/main.c: return 1 from handled __setup() functions")
... passing "rodata=full" would result in a spurious warning from the
__setup() handler (though RO permissions would be configured
appropriately).
Further, "rodata=full" has been broken since commit:
0d6ea3ac94ca77c5 ("lib/kstrtox.c: add "false"/"true" support to kstrtobool()")
... which caused strtobool() to parse "full" as false (in addition to
many other values not documented for the "rodata=" kernel parameter.
This patch fixes this breakage by:
* Moving the core parameter parser to an __early_param(), such that it
is available early.
* Adding an (optional) arch hook which arm64 can use to parse "full".
* Updating the documentation to mention that "full" is valid for arm64.
* Having the core parameter parser handle "on" and "off" explicitly,
such that any undocumented values (e.g. typos such as "ful") are
reported as errors rather than being silently accepted.
Note that __setup() and early_param() have opposite conventions for
their return values, where __setup() uses 1 to indicate a parameter was
handled and early_param() uses 0 to indicate a parameter was handled.
Fixes: f9a40b089065 ("init/main.c: return 1 from handled __setup() functions")
Fixes: 0d6ea3ac94ca ("lib/kstrtox.c: add "false"/"true" support to kstrtobool()")
