From 16c675f9893fffd8a4fd408c42d9ff050e022e58 Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Fri, 18 Apr 2014 20:12:50 +0200 Subject: pinctrl: sunxi: Move Allwinner A31 special pins driver to a driver of its own Move the pin description to a driver specific to be. This is one more step toward retiring pinctrl-sunxi-pins.h that used to define all the pins for all the Allwinner SoCs in a single header, that would have in turn result in having these structures in the final binary as many times as the header was included.
