[PATCH 3/3] arm64: dts: rockchip: add support for NanoPi M6 board

[Joachim Eastwood via B4 Relay]

From: Joachim Eastwood <joachim.eastwood at gmail.com>

The NanoPi M6V2 board is an updated version of the original M6 board
with the following changes.
* New audio CODEC (Everest ES8389)
* New Ethernet PHY (MotorComm YT8531C)
* 1 extra user button
* Misc connector changes on the board

The codec_es_3v3 regulator enable pin is hardwired to the 5V input rail.
