[PATCH RESEND v2 0/4] Using i2c-hid-of-elan driver instead of i2c-hid-of driver

[PATCH RESEND v2 0/4] Using i2c-hid-of-elan driver instead of i2c-hid-of driver

[Hsin-Te Yuan]

After commit 2be404486c05 ("HID: i2c-hid-of: Add reset GPIO support to
i2c-hid-of"), i2c-hid-of driver resets the touchscreen without having
proper post-reset delay on OF platform.  From the commit message of that
commit, not to decribe poset-reset delay in device tree is intended.
Instead, describing the delay in platform data and changing to use
specialized driver is more preferable solution.

Also workaround the race condition of pinctrl used by touchscreen and
trackpad in this series to avoid merge conflict.

Adding other second source touchscreen used by some mt8183 devices in
this series since this should be based on the workaround of pinctrl
issue.

Changes in v2:
- Add second source touchscreen patches since they should based on the
  first patch of this series.
- Link to v1: https://lore.kernel.org/r/20241018-post-reset-v1-0-5aadb7550037@chromium.org

[PATCH RESEND v2 1/4] arm64: dts: mediatek: mt8183: Fix race condition of pinctrl

[Hsin-Te Yuan]

Some mt8183 devices use second source touchscreen/trackpad and share the
same pinctrl property with the original touchscreen/trackpad. Currently,
multiple touchscreen/trackpad drivers might probe simultaneously,
causing a race condition of getting the same pin.

Move the pinctrl property to the i2c node to workaround this issue.

[PATCH RESEND v2 2/4] arm64: dts: mediatek: mt8183: Switch to Elan touchscreen driver

[Hsin-Te Yuan]

After commit 2be404486c05 ("HID: i2c-hid-of: Add reset GPIO support to
i2c-hid-of"), the i2c-hid-of driver used by some mt8183 devices resets
the touchscreen without having enough post-reset delay. This makes those
touchscreen fail to get probed.

Switch to Elan touchscreen driver, which has enough post-reset delay.

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade


New warnings running 'make CHECK_DTBS=y mediatek/mt8183-kukui-jacuzzi-burnet.dtb mediatek/mt8183-kukui-jacuzzi-cozmo.dtb mediatek/mt8183-kukui-jacuzzi-damu.dtb mediatek/mt8183-kukui-jacuzzi-fennel-sku1.dtb mediatek/mt8183-kukui-jacuzzi-fennel-sku6.dtb mediatek/mt8183-kukui-jacuzzi-fennel-sku7.dtb mediatek/mt8183-kukui-jacuzzi-kenzo.dtb mediatek/mt8183-kukui-jacuzzi-pico.dtb mediatek/mt8183-kukui-jacuzzi-pico6.dtb' for 20241105-post-reset-v2-0-c1dc94b65017@chromium.org:

The switch to i2c-hid-of-elan is okay, but the pinctrl hack is not necessary
anymore, as it does get resolved with the hwprober from Chen-Yu

https://lore.kernel.org/all/20241106093335.1582205-1-wenst@chromium.org/

Please redo the second source TS addition based on that series instead.

Thanks,
Angelo
