Hello, I try to use the GPIO2_IO20 and the GPIO2_IO21 as GPIO pin for uart modem signals and not as PIN to the USDHC1 sdcard interface of the imx6ulevk.
if I write 5 direct to the MUX Ctrl Register devmem2 0x020e01cc w 5 devmem2 0x020e01d0 w 5 it works until next boot. I assume that I have to change something in the device tree files of linux to reflect the HW gpio changes. How do I adjust the imx6ul-14x14-evk-csi.dts for this?
