[PATCH v2 0/4] Using i2c-hid-of-elan driver instead of i2c-hid-of driver
Posted by Hsin-Te Yuan 1 month, 1 week ago
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

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
