From d54dbb5000fca9863e8a2cb0e6467a424a1eb6e0 Mon Sep 17 00:00:00 2001 From: Shawn Guo Date: Thu, 28 Jun 2012 11:44:58 +0800 Subject: ARM: dts: mxs: add hog-gpios for imx23-evk and imx28-evk Before gpio_request can directly ask pinctrl system to configure the requested pin into gpio mode, we use "hog" entry (pinctrl state of pin controller itself) to configure gpios.
