From 542a564d2ddbd2c37536b4dff8e45fa0fc239bcc Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Thu, 7 Mar 2013 14:31:57 +0100 Subject: [PATCH] sh-pfc: Make function GPIOs support optional The target is to get rid of function GPIOs completely. To reach this, make function GPIOs support optional by skipping the function GPIO chip registration if no function GPIOS are defined in SoC data.
