From 1a4fd58f76cf331c93daaa1667daa25db297d0d4 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Sun, 10 Mar 2013 03:19:44 +0100 Subject: [PATCH] sh-pfc: Make GPIO support optional When implemented as a separate IP block, GPIOs should be handled by a separate driver. To make this possible GPIO support needs to be optional in the sh-pfc driver. If no GPIO data registers are supplied in the SoC information structure skip registration of the gpiochip.
