[PATCH v7 2/3] MIPS: DTS: CI20: multiple DTS improvements

H. Nikolaus Schaller
2020-03-06T21:06:43Z

a) add DT node for SW1 as Enter button

The SW1 button can be used as a simple one-button keyboard
and is connected to PD17.

Note: SW1 has a second meaning to change the boot sequence
when pressed while powering on.

b) give eth0_power a defined voltage.

This is a 3.3V power switch (DVNET3.3V).
