[PATCH 4.1 134/202] dts: imx25: fix sd card gpio polarity specified in device tree

From: Greg Kroah-Hartman
Date: Sat Oct 17 2015 - 22:31:52 EST


4.1-stable review patch. If anyone has any objections, please let me know.

------------------

From: Dong Aisheng <aisheng.dong@xxxxxxxxxxxxx>

commit cf75eb15be2bdd054a76aeef6458beaa4a6ab770 upstream.

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().
