If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From aca45c0e95dad1c4ba4d38da192756b0e10cbbbd Mon Sep 17 00:00:00 2001 From: Dong Aisheng <aisheng.dong@xxxxxxxxxxxxx> Date: Wed, 22 Jul 2015 20:53:00 +0800 Subject: dts: imx51: fix sd card gpio polarity specified in device tree From: Dong Aisheng <aisheng.dong@xxxxxxxxxxxxx> commit aca45c0e95dad1c4ba4d38da192756b0e10cbbbd 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().
