Subject: [PATCH 0/5] regulator: mp8859: add driver for DC/DC converter used on rk3399-roc-pc board

On rk3399-roc-pc board a voltage regulator MP8859 from Monolithic Power Systems
is used to supply the 12V power line. This delivers 5V as a default value after
boot. The voltage is controllable via I2C.
Add a basic driver to set and get the voltage of the MP8859 and add a matching
node with fixed 12V in the DT of the board. 

Markus Reichl (5):
  regulator: mp8859: add driver
  regulator: mp8859: add config option and build entry
  dt-bindings: add vendor Monolithic Power Systems
  dt-bindings: regulator: add MPS mp8859 voltage regulator
  arm64: dts: rockchip: Enable mp8859 regulator on rk3399-roc-pc
