I would need to set some TAMPER GPIOs at boot time: MX6UL_PAD_SNVS_TAMPER4__GPIO5_IO06, e
It is enough to do it in the barebox device tree setting them ACTIVE HIGH. If so where exactly in the device tree?
Also I am trying to assign some signals to different GPIOs as the default GPIOs are used by other kernel modules.
I could not find programming model for imx6ul or GPIO details in the hardware manual/application processor manual.
Could somebody point me to the imx6ul documentation that explains GPIOs registers and functions ?
