Wakeup for IRQ1 should be disabled only in cases where i8042 had
actually enabled it, otherwise "wake_depth" for this IRQ will try to
drop below zero and there will be an unpleasant WARN() logged:
kernel: atkbd serio0: Disabling IRQ1 wakeup source to avoid platform firmware bug
kernel: ------------[ cut here ]------------
kernel: Unbalanced IRQ 1 wake disable
kernel: WARNING: CPU: 10 PID: 6431 at kernel/irq/manage.c:920 irq_set_irq_wake+0x147/0x1a0
The PMC driver uses DEFINE_SIMPLE_DEV_PM_OPS() to define its dev_pm_ops
which sets amd_pmc_suspend_handler() to the .suspend, .freeze, and
.poweroff handlers. i8042_pm_suspend(), however, is only set as
the .suspend handler.
Fix the issue by call PMC suspend handler only from the same set of
dev_pm_ops handlers as i8042_pm_suspend(), which currently means just
the .suspend handler.
To reproduce this issue try hibernating (S4) the machine after a fresh boot
without putting it into s2idle first.

Previously, AMD's Ryzen Desktop SoCs did not include support for STB.
However, to accommodate this recent change, PMFW has implemented a new
message port pair mechanism for handling messages, arguments, and
responses, specifically designed for distinguishing from Mobile SoCs.
Therefore, it is necessary to update the driver to properly handle this
incoming change.
Add a new function amd_stb_update_args() to simply the arguments that
needs to be passed between S2D supported Mobile SoCs vs Desktop SoCs.

Since S2D (Spill to DRAM) uses different message port offsets compared to
PMC message offsets for communication with PMFW, relocate the S2D macros
from pmc.c to a new file, mp1_stb.c, for better code organization.
Following this change, it is logical to introduce a new structure,
"struct stb_arg," to pass the message, argument, and response offset
details to PMFW via the amd_pmc_send_cmd() call. Additionally, move the
s2d_msg_id member from amd_pmc_dev into the new structure.

As the SoC evolves with each generation, the dynamics between the PMC and
STB layers within the PMC driver are becoming increasingly complex, making
it challenging to manage both in a single file and maintain code
readability.
Additionally, during silicon bringup, the PMC functionality is often
enabled first, with STB functionality added later. This can lead to missed
updates in the driver, potentially causing issues.
To address these challenges, it's beneficial to move all STB-related
changes to a separate file. This approach will better accommodate newer
SoCs, provide improved flexibility for desktop variants, and facilitate
the collection of additional debug information through STB mechanisms.
Also the additional checks for entering s2d_init have been moved from
the PMC probe to amd_pmc_s2d_init(). This adjustment makes more sense
following the transfer of code to the separate mp1_stb.c file.

Transfer the support for STB-related file operations to the
amd_pmc_s2d_init() function, thereby consolidating the STB and S2D
(Spill to DRAM) functionality in one location. Also, relocate the
call to amd_pmc_s2d_init() to occur after the creation of the
"amd_pmc" debugfs directory. This ensures that the driver's root debugfs
directory is established beforehand.
For older platforms that supported S2D, exit immediately after creating
debugfs. These platforms may not support the PMFW messages available on
newer platforms. This adjustment is necessary due to the relocation of
debugfs creation into amd_pmc_s2d_init().

- list_for_each_reverse() removal, no one was using it!
- last-minute seq_printf() format string bug found and fixed in many

- minor bugfixes and changes full details in the shortlog
As mentioned above, there is 2 merge conflicts with your tree, one is
where the file is removed (easy enough to resolve), the second is a
build time error, that has been found in linux-next and the fix can be
seen here:

Firmware is updated to send HSMP_ERR_PREREQ_NOT_SATISFIED(0xFD) and
HSMP_ERR_SMU_BUSY(0xFC) error codes. Add them here.
Add error logs to make it easy to understand the failure reason for
different error conditions.
Replace pr_err() with dev_err() to identify the driver printing the
error.

AMD X3D processors, also known as AMD 3D V-Cache, feature dual Core
Complex Dies (CCDs) and enlarged L3 cache, enabling dynamic mode
switching between Frequency and Cache modes. To optimize performance,
implement the AMD 3D V-Cache Optimizer, which allows selecting either:
Frequency mode: cores within the faster CCD are prioritized before
those in the slower CCD.
Cache mode: cores within the larger L3 CCD are prioritized before
those in the smaller L3 CCD.

Use platform_get_resource() to fetch the memory resource instead of
acpi_walk_resources() and devm_ioremap_resource() for mapping the
resources.
PS: We cannot use resource_size() here because it adds an extra byte to
round off the size. In the case of PMF ResourceTemplate(), this rounding
is already handled within the _CRS. Using resource_size() would increase
the resource size by 1, causing a mismatch with the length field and
leading to issues. Therefore, simply use end-start of the ACPI resource to
obtain the actual length.

Then use is_visible to enable only the necessary files on the platform.
.read() and .is_bin_visibile() have slightly different
implemetations on ACPI and non-ACPI system, so move them

Provide a Kconfig option to choose between ACPI or the platform device
based driver. The common code which is the core part of the HSMP driver
maintained at hsmp.c is guarded by AMD_HSMP config and is selected by
these two driver configs. This will be built into separate hsmp_common.ko
module and acpi as hsmp_acpi and plat as amd_hsmp respectively.
Also add "|| COMPILE_TEST" clause in Kconfig to get build coverage for
