Subject: mx6ul_14x14_evk: don't use array for SD2 card detect pad
X-Git-Tag: KARO-TXSD-2017-03-15~197^2~11
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=eb3813ad1afb29401fce20e9553df71e98f4aeec;p=karo-tx-uboot.git

mx6ul_14x14_evk: don't use array for SD2 card detect pad

Only a single pad is changed to change sdhc2_dat3 from an
SDIO pin to and from GPIO4:5, so remove the array and use
the imx_iomux_v3_setup_pad() routine.
