From e36142143005e86d2d083d9549836c32bb3a6120 Mon Sep 17 00:00:00 2001 From: Mugunthan V N Date: Mon, 4 Apr 2016 17:28:03 +0530 Subject: ARM: dts: dra7xx: am57xx: fix cd-gpios definition as per hardware design and dt binding docs As per mmc device tree binding documentation card detect gpio has to be active low signal. When a hardware is designed with active high card detect, gpio polarity has to be changed with cd-inverted dt property. In DRA72x and AM57xx EVMs the card detect gpio is designed as active low gpio. So correcting the dt card detect gpio definition. Also adding card-detect gpio for DRA74x EVM.
