commit a218235f7b7fcb8671e0ae39c21b5eff9bbd25ea Author: Duncan Laurie dlaurie@chromium.org Date: Fri Oct 4 11:54:04 2013 -0700
lynxpoint: Add interrupt for GPIO controller in ACPI device
The GPIO controller uses IRQ14 as an active high level triggered source for GPIOs that are configured to trigger shared interrupt.
This was also tested on bolt by configuring the touchscreen to use a shared GPIO interrupt:
localhost ~ $ grep atmel_mxt_ts /proc/interrupts 54: 24 188 93 124 LP-GPIO-demux atmel_mxt_ts
