From b53bc2819a71099ecfc3d61ba0796b3dcc6be321 Mon Sep 17 00:00:00 2001 From: Shiraz Hashim Date: Fri, 16 Nov 2012 10:45:25 +0530 Subject: gpio: SPEAr: add spi chipselect control driver 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 commit intends to provide the spi chipselect control in software over gpiolib interface. spi chip drivers can use the exported gpiolib interface to define their chipselect through DT or platform data.
