Subject: [PATCH 5/5] arm64: dts: rockchip: Enable mp8859 regulator on rk3399-roc-pc
Date: Mon,  6 Jan 2020 22:16:28 +0100	[thread overview]
Message-ID: <20200106211633.2882-6-m.reichl@fivetechno.de> (raw)
In-Reply-To: <20200106211633.2882-1-m.reichl@fivetechno.de>

The rk3399-roc-pc uses a MP8859 DC/DC converter for 12V supply.
This supplies 5V only in default state after booting.
Now we can control the output voltage via I2C interface.
Add a node for the driver to reach 12V.
