Subject: [PATCH V2 05/11] dts: imx7: fix sd card gpio polarity specified in device tree
Date: Wed, 22 Jul 2015 20:53:04 +0800	[thread overview]
Message-ID: <1437569590-5228-6-git-send-email-aisheng.dong@freescale.com> (raw)
In-Reply-To: <1437569590-5228-1-git-send-email-aisheng.dong@freescale.com>

cd-gpios polarity should be changed to GPIO_ACTIVE_LOW and wp-gpios
should be changed to GPIO_ACTIVE_HIGH.
Otherwise, the SD may not work properly due to wrong polarity inversion
specified in DT after switch to common parsing function mmc_of_parse().
