platform/x86: ISST: Correct locked bit width

2026-04-02T11:07:25+00:00

commit fbddf68d7b4e1e6da7a78dd7fbd8ec376536584a upstream. SST-PP locked bit width is set to three bits. It should be only one bit. Use SST_PP_LOCK_WIDTH define instead of SST_PP_LEVEL_WIDTH.

platform/olpc: olpc-xo175-ec: Fix overflow error message to print inlen

[ Upstream commit 2061f7b042f88d372cca79615f8425f3564c0b40 ] The command length check validates inlen (> 5), but the error message incorrectly printed resp_len. Print inlen so the log reflects the actual command length.

platform/x86: touchscreen_dmi: Add quirk for y-inverted Goodix touchscreen on SUPI S10

2026-04-02T11:07:14+00:00

[ Upstream commit 7d87ed70fc95482c12edf9493c249b6413be485e ] The touchscreen on the SUPI S10 tablet reports inverted Y coordinates, causing touch input to be mirrored vertically relative to the display. Add a quirk to set the "touchscreen-inverted-y" boolean device-property on the touchscreen device, so that the goodix_ts driver will fixup the coordinates.

platform/x86: intel-hid: Enable 5-button array on ThinkPad X1 Fold 16 Gen 1

2026-04-02T11:07:13+00:00

[ Upstream commit b38d478dad79e61e8a65931021bdfd7a71741212 ] The Lenovo ThinkPad X1 Fold 16 Gen 1 has physical volume up/down buttons that are handled through the intel-hid 5-button array interface. The firmware does not advertise 5-button array support via HEBC, so the driver relies on a DMI allowlist to enable it. Add the ThinkPad X1 Fold 16 Gen 1 to the button_array_table so the volume buttons work out of the box.

Without this, the chassis state is not reported, and the hinge rotation only emits unknown scancodes. Verified on Dell 14 Plus 2-in-1 DB04250.

platform/x86/amd/pmc: Add support for Van Gogh SoC

[ Upstream commit db4a3f0fbedb0398f77b9047e8b8bb2b49f355bb ] The ROG Xbox Ally (non-X) SoC features a similar architecture to the Steam Deck. While the Steam Deck supports S3 (s2idle causes a crash), this support was dropped by the Xbox Ally which only S0ix suspend. Since the handler is missing here, this causes the device to not suspend and the AMD GPU driver to crash while trying to resume afterwards due to a power hang.
