Change subject: google/gru: enable the pull high for touchpad ......................................................................
Patch Set 2:
Sorry, I don't quite understand what problem is solved here. Do you have a link to a Google bug with more information? (It's okay to put BUG=b:XXXX lines in these patches, even if they're access-restricted.)
The touchpad is not accessed by the firmware and the kernel should reset it when it's initializing. Why does this GPIO have to be configured in firmware? What's the harm in doing it later?
