commit 050c11a424056497f9f1b6e6e0e93d1321feda04 Author: Duncan Laurie dlaurie@chromium.org Date: Tue May 7 11:31:33 2013 -0700
haswell: Update ChromeOS ACPI GPIO package
The chromeos_acpi driver sysfs naming is not what crossystem expects if there is just one entry in the package because it does not add a ".#" suffix in that case.
Specify all the expected GPIOs on wtm2 as undefined, which should be 0xFF and not 0x00 becuase 0 is a valid GPIO.
