Interface SD card on uSDHC2

[jigneshpatel]

Hi,

I am Working on iMX6ul using Linux.

SD card has successfully interface on uSDHC1. I can successfully boot and also save data to SD card.

Now I have to change SD pinmux as per below.

uSD card PIN	uSDHC2 pinmux	Imx6ul pin
SD1_DATA0	USDHC2_DATA0	GPIO4_21
SD1_DATA1	USDHC2_DATA1	GPIO4_22
SD1_DATA2	USDHC2_DATA2	GPIO4_23
SD1_DATA3	USDHC2_DATA3	GPIO4_24
SD1_CMD	USDHC2_CMD	GPIO4_20
SD1_CLK	USDHC2_CLK	GPIO4_19

What change need in Linux kernel file .dtsi and uboot  file to interface uSD card as above configuration?

Thanks,

JP
