From 7cef07d5cd25b1286376d1e8948f75b89d34a37e Mon Sep 17 00:00:00 2001 From: Shiraz Hashim Date: Mon, 3 Sep 2012 11:46:58 +0530 Subject: [PATCH] ARM: SPEAr13xx: DT: Add spics gpio controller nodes SPEAr platform provides a provision to control chipselects of ARM PL022 Prime Cell spi controller through its system registers, which otherwise remains under PL022 control which some protocols do not want. This patch adds spics controller nodes in device tree for various SPEAr13xx SoCs.
