From 8320062928161911bc46b0340e5a7cc0b3e3bb8e Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Mon, 3 Feb 2014 14:32:20 +0100 Subject: ARM: ux500: move AB8500 GPIOs to device tree Move the AB8500 muxing and biasing settings over from the board file to the device tree, include it in the reference designs using the AB8500: HREF prior to v60, v60plus and Snowball. Set up these GPIO lines using hogs, just like in the board file.
