the following patch was just integrated into master: commit b576e6f236fd374421287f39542a9e26608406ff Author: Kevin Chiu Kevin.Chiu@quantatw.com Date: Sat Feb 4 03:55:01 2017 +0800
Revert "google/pyro: remove Wacom touchscreen probed flag"
Reason for revert: Pyro has two touchscreen sources: WACOM/ELAN. It will not have both touchscreen IC in one system at the same time.
So the "probed" property of WACOM i2c device is mandatory to set for kernel to know whether it exists before driver initializes it.
Otherwise in ELAN case, when driver fails to init WACOM i2c device, ACPI _OFF will be invoked to set GPIO#152 low to cut off power.
