commit 77a1a7a8e6cfd469917a8f530d0b9d83d71d43e4 Author: Shaunak Saha shaunak.saha@intel.com Date: Fri Jun 10 19:36:49 2016 -0700
intel/amenia: GPE routing for amenia
This patch sets the devicetree for gpe0_dw configuration and also confgigures the GPIO lines for SCI.EC_SCI_GPI is configured to proper value and the gpio_tier1_sci_en bit in acpi register is set by adding a dummy method in GPE scope.
BUG = chrome-os-partner:53438 TEST = Toggle pch_sci_l from ec console using gpioset command and see that the sci counter increases in /sys/firmware/acpi/interrupt and also 9 in /proc/interrupt
