Hello, this is simple question. I want use GPIO1_7 so if I only must set configuration in device tree ? because I can sets /sys/class/gpio75 (GPIO3_IO11), but there is no any information about this pin in my device tree.
Can I take my ready *.dtsi file and add GPIO1_07 support without build all image ? I use bitbake.
Regards,
Adrian

Thanks Igor, I can now set device tree and it works, but in my board cc imx6ul SBS express there is User led on pin GPIO3_IO11 and it configuration should be in imx6ul-ccimx6ulstarter .dtsi/.dts but there is no any code about it. so there is another place where I can define this ?

Hi Adrian
you can add some configuration for this pin in uboot.

But If I make this with u-boot will it not be overridden by the kernel ?
