This update introduces support for Google touchscreen devices
to the existing framework, enhancing compatibility with Google's
hardware interfaces. It extends the fw_config field with new
options to accommodate different connection types used by Google
touchscreens. Specifically, it adds:
- TOUCHSCREEN_LPSS_I2C_ELAN_REX for ELAN9006 interfaced via LPSS-I2C.
- TOUCHSCREEN_THC_SPI_ELAN_REX for ELAN6918 interfaced via THC-SPI.
- TOUCHSCREEN_THC_I2C_ELAN_REX for ELAN9006 interfaced via THC-I2C.
BUG=none
TEST=Connect Google's REX touchscreen with the conversion cables. Boot
to OS with fw_config setting for Google's touchscreen and verify
device enumeration in /sys/bus/hid/devices directory.
