Chromebooks use coreboot for system initialization. coreboot has always had the default mainboard vendor string for Google machines set to "Google". Google engineers set this string to "GOOGLE" in the coreboot copies of the Chromium OS tree. The atmel_mxt_ts driver in it's current state is set to match the latter case, i.e. it will only bind to a Chromebook's touchscreen either if the device uses the downstream coreboot firmware (providing the matching mainboard vendor string), or if a user running upstream coreboot has manually set the string to "GOOGLE". This patch adds a match for coreboot's default. Signed-off-by: Jean Lucas <jean@4ray.co> --- drivers/input/touchscreen/atmel_mxt_ts.c | 8 ++++++++ 1 file changed, 8 insertions(+)
