Bug description:
[SRU Justification]
[Impact]
On AMD Yellow Carp B0 platforms, S0i3 is still not working.
[Fix]
This denpends on a few fixes for kernel driver that are all either in
v5.17-rc1 or in stable linux-5.1x.y, along with an already upstreamed
dmcub firmware.
[Test Case]
On AMD RMT CRB board,
1. apply both kernel and firmware fixes
2. module blacklist amd_sfh as it's still under development,
3. trigger system suspend. Use power button to wake up the device.
4. check /sys/kernel/debug/amd_pmc/s0ix_stats, the values shall be non-zero
On without any of above, the board may not cut device power during
suspend, and/or fail to resume and leaving a blank screen, and/or s0ix
stats remain all zeros.
[Where problems could occur]
On AMD RMT CRB board, Sensor Fusion Hub (amd_sfh) still doesn't
support S0ix and has to be disabled. For the kernel side, the driver
fixes addressed a few procedure errors that should be unlikely to
introduce regressions; for the firmware side, also tested loading new
firmware on unpatched kernels and there is no difference found yet.
[Other Info]
For kernel driver fixes, patches for both oem-5.14 and jammy are
necessary; for firmware, that has been available in jammy branch but
not yet released, so only Focal will be nominated.
