From df0c6c80232f2ad442dcf79a3a420eb8ac624e42 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Mon, 14 Apr 2014 20:33:13 +0200 Subject: [PATCH] gpio: rcar: Add minimal runtime PM support This is just enough to automatically enable the functional clock, if present. Clock management during suspend/resume is still to be added.
