From 8cdeef1c0d1e6453a027642d2504e58ab9ac7152 Mon Sep 17 00:00:00 2001 From: Vaibhav Shankar Date: Wed, 14 Sep 2016 10:39:29 -0700 Subject: [PATCH] mainboard/google/reef: Configure PERST_0 pin This configures PERST_0 in devicetree. For boards without PERST_0, the pin should be disabled. For boards with PERST_0 the correct GPIO needs to be assigned.
