Thanks, that makes it simple: the interrupt controller, I2C and GPIO
nodes stay as they are, and the pin controller, when it comes, gets one
node for the five mux registers.

I checked the boot loader's pin mux on the board: it leaves the reset
button line and the touchscreen interrupt line muxed to GPIO, so the
dts does not change with the mux register gone from the GPIO binding.

Noted. Arnd also asked to wait for the 7.4 merge window to close, so the
next version comes on top of v7.4-rc1.

Thanks,
