LF-4184-1 arm64: dts: imx8ulp-evk-rk055hdmipi4m: add touch support
Add GOODIX GT911 touch support.
The irq pad of this touch is connect to PTB5, which is in M domain.
So this touch depends on rpmsg-gpio output/input function and rpmsg-gpio
interrupt function, please refer to drivers/gpio/gpio-imx-rpmsg.c
This means to support this touch, M core image also need to add related
rpmsg-gpio output/input/interrupt function.
