From 76d47fea7ec6a5d2049142dfcbea88cd175bd51e Mon Sep 17 00:00:00 2001 From: Jimmy Huang Date: Sat, 5 Mar 2016 00:53:25 +0800 Subject: [PATCH] mt8173: Remove gpio driver support We no longer need to control power signal via gpio during system off, thus remove gpio driver support from platform code.
