ARM: dts: imx53-qsb: Describe the esdhc1 card detect pin
The micro SD card slot uses GPIO3_13 as card detect pin, so describe it in the devicetree. This was noticed when converting imx53-qsb board to driver model in U-Boot as the micro SD card was not getting detected. After this change it is possible to load the dtb and zImage from the SD card and boot Linux. Signed-off-by: Fabio Estevam <festevam@gmail.com>
