From a3b8d4a513574e6adf76bcacad21c95ee6b8ce4b Mon Sep 17 00:00:00 2001 From: Alexander Shiyan <shc_work@mail.ru> Date: Tue, 9 Oct 2012 20:05:56 +0400 Subject: GPIO: Add support for GPIO on CLPS711X-target platform The CLPS711X CPUs provide some GPIOs for use in the system. This driver provides support for these via gpiolib. Due to platform limitations, driver does not support interrupts, only inputs and outputs.

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.
