From b0f81518b5c17466bc95ebdef292e82c4b76bc88 Mon Sep 17 00:00:00 2001 From: Aaron Durbin Date: Mon, 25 Jul 2016 21:31:41 -0500 Subject: chromeos mainboards: remove chromeos.asl Use the ACPI generator for creating the Chrome OS gpio package. Each mainboard has its own list of Chrome OS gpios that are fed into a helper to generate the ACPI external OIPG package. Additionally, the common chromeos.asl is now conditionally included based on CONFIG_CHROMEOS.
