From c34079cea0990d184fe2b13065066d012dfdd93d Mon Sep 17 00:00:00 2001 From: Karthikeyan Ramasubramanian Date: Tue, 7 Jul 2020 22:27:10 -0600 Subject: mb/google/dedede: Add ability to provide override GPIO table For variants with slightly different GPIO configuration, add support to pass an override GPIO configuration table. BUG=None TEST=Build and boot the waddledee mainboard.
