From 05201d778336f474e3f9df55431340fa95521aee Mon Sep 17 00:00:00 2001 From: Aaron Durbin Date: Fri, 23 Sep 2016 16:06:14 -0500 Subject: ec/google/chromeec: provide optional ASL lid switch implementation Instead of relying on the mainboards to provide their own LID0 ACPI device, provide the infrastructure so that the mainboards can signal to the EC ASL code to provide the default lid switch implementation.
