Subject: [PATCH 4/5] dts: imx25: fix sd card gpio polarity specified in device tree
Date: Thu, 18 Jun 2015 01:33:37 +0800 [thread overview]
Message-ID: <1434562418-24090-5-git-send-email-aisheng.dong@freescale.com> (raw)
In-Reply-To: <1434562418-24090-1-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().
