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. Signed-off-by: Markus Reichl <redacted> --- .../boot/dts/rockchip/rk3399-roc-pc.dtsi | 32 +++++++++++-------- 1 file changed, 18 insertions(+), 14 deletions(-)
