[PATCH 5/5] ARM: dts: imx7-colibri: add Carrier Board 3.3V/5V regulators

From: Stefan Agner
Date: Wed Mar 29 2017 - 19:19:49 EST


Model the Carrier Board power distribution by adding a fixed 3.3V
and 5V regulator. The 3.3V regulator is connected to the backlight
as well as the display supply. The 5V regulator is used to supply
USB VBUS.
