From 32ca3cd246746c2a1d584e4a63bcd43ebb7fe23f Mon Sep 17 00:00:00 2001 From: Duncan Laurie Date: Fri, 12 Oct 2018 17:19:53 -0700 Subject: ec/google/chromeec: Use common MEC interface Switch to using the common MEC interface instead of the Chrome EC specific code. Tested on a Chell chromebook that has a MEC based Chrome EC to ensure that the EC interface is still functional.
