From a3d6e386176e3702d8f975b1c2b10162c3e15fc0 Mon Sep 17 00:00:00 2001 From: Ye.Li Date: Tue, 4 Nov 2014 15:35:49 +0800 Subject: mmc: fsl_esdhc: Update esdhc driver for iMX6SX The reset value of "uSDHCx_INT_STATUS_EN" register is changed to 0 on iMX6SX. So the fsl_esdhc driver must update to set the register, otherwise no state can be detected.
