MLK-15950 input: egalax_ts: switch to i2c interface before wake up For HannStar (HSD100PXN1 Rev: 1-A00C11 F/W:0634) LVDS touch screen, it has a special request for the EETI touch controller. The host needs to trigger I2C event to device FW at booting first, and then the FW can switch to I2C interface. Otherwise, the FW can’t work with I2C interface, and can't generate any interrupt when touch the screen. This patch send an I2C command before the device wake up, make sure the device switch to I2C interface first.
