From 8d99339710ac9bd1eca8f04a356752c89dc7cf0b Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Tue, 19 Nov 2013 23:02:11 +0100 Subject: pinctrl: nomadik: move platform data handling into driver This decomissions the platform data header (which is no longer in use after the systems using this driver were switched to a pure device-tree config path) and merges the result into the driver file or local driver header.
