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

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.
