[PATCH v2 0/2] platform/x86: uniwill-laptop: Support the PCSpecialist Recoil 16 AMD

[Mohamed Jouini]

The PCSpecialist Recoil 16 AMD is a rebadged TUXEDO Stellaris 16 Gen7 AMD
(board X6FR57TY), which the driver does not match today because of the
different DMI vendor and board name.

Patch 1 adds it with the existing Stellaris 16 Gen7 AMD feature set.
Patch 2 maps the "Sc" key (WMI event 0xD0) to KEY_ROTATE_DISPLAY.

Tested on the Recoil 16 AMD (BIOS N.1.39PCS10) with the driver from this
series built against 7.2.7: the Sc key, the hwmon fan and temperature
readings, and all three charging profiles. Charging from below 70%,
with the charge counted from current_now:

  Profile    CV (4S)    per cell   stops at, of a Standard charge
  Standard   17.405 V   4.35 V     100%
  Long_Life  17.194 V   4.30 V     about 93%
  Trickle    16.818 V   4.20 V     about 90%

In every profile the EC then reports 100% / Full, as Armin said it
would.

Changes in v2:
- Patch 1 uses the existing Stellaris 16 Gen7 AMD feature set (charging
  profiles) instead of the percentage charge limit (Armin).
- Dropped the platform profile patch for now (Armin).
- Added Armin's Reviewed-by to the Sc key patch. On whether TUXEDO knows
  more about event 0xD0: tuxedo-drivers (4.24.0) has no entry for it in
  its Uniwill keymap, so it only reaches the "Unknown code" debug message
  there.

Regarding EC_ADDR_CHARGE_CTRL from the v1 review: it needs no cleanup. It
was 0 before v1 was ever loaded, and after a power cycle without the
driver the EC had reset it to 0 on its own.

[PATCH v2 1/2] platform/x86: uniwill-laptop: Add PCSpecialist Recoil 16 AMD

[Mohamed Jouini]

The PCSpecialist Recoil 16 AMD is a rebadged TUXEDO Stellaris 16 Gen7 AMD
but reports sys_vendor "PCSpecialist" and board name "X6FR57TY", so the
existing entry does not match it. Use the Stellaris 16 Gen7 AMD feature
set.

Changes in v2:
- Use the existing Stellaris 16 Gen7 AMD feature set (charging profiles)
  instead of a separate descriptor with the percentage charge limit.

Hi,

The descriptors were renamed by recent work so could you please rebase 
this on top of the for-next branch and send v3.

[PATCH v2 2/2] platform/x86: uniwill-laptop: Map the screen rotation key

[Mohamed Jouini]

The PCSpecialist Recoil 16 AMD / TUXEDO Stellaris 16 Gen7 chassis has an
"Sc" key next to F12, meant to rotate the lay-flat screen by 180 degrees.
It reports WMI event 0xD0, which is currently reported as KEY_UNKNOWN.
Map it to KEY_ROTATE_DISPLAY.

- Added Reviewed-by. tuxedo-drivers (4.24.0) has no entry for event 0xD0
  in its Uniwill keymap; there it only reaches the "Unknown code" debug

Thank you for your contribution, it has been applied to my local
review-ilpo-next branch. Note it will show up in the public
platform-drivers-x86/review-ilpo-next branch only once I've pushed my
local branch there, which might take a while.

FYI [if applicable to your patch], as per Linus' policy change, also
fixes are mostly routed through for-next unless the fix is for a
commit introduced in the most recent cycle or is clearly a regression
fix.
