Subject: [PATCH 5/5] ARM: dts: imx7-colibri: add Carrier Board 3.3V/5V regulators
Date: Wed, 29 Mar 2017 16:21:13 -0700	[thread overview]
Message-ID: <20170329232113.19078-5-stefan@agner.ch> (raw)
In-Reply-To: <20170329232113.19078-1-stefan@agner.ch>

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.
