Hi,
this short series adds GPIO keys and leds to the device tree of the r8a7793 based Gose board.
It uses the makes use of the recently addition of GPIO devices to the device tree of the r8a7793. Thanks Magnus!
I have booted a system with these changes and verified that the relevant entries appear to be present in sysfs.
I have not tested button press events or illumination of the leds as I do not currently have physical access to a Gose board.

So I've now managed to test the GPIO keys and LED devices on a physical Gose board. The LED6 -> LED 8 entries will be lit as expected by controlling brightness in
/sys/class/leds/. The GPIO keys associated with buttons SW30 to SW36 and the dip switch SW2 all generate interrupts in/proc/interruptson key press or dip switch change. All good!
