[PATCH v3 0/3] arm64: dts: renesas: r8a779a0 DU support

[PATCH v3 0/3] arm64: dts: renesas: r8a779a0 DU support

[Kieran Bingham]

Provide the DT nodes for the DU, and DSI found on the r8a779a0, and
extend the falcon-cpu board add on with the TI SN65DSI86 bridge which is
used to connect the DSI output to the mini display-port connector on the
Falcon CPU board.

I'm not sure if EXTAL is the right clock, the datasheet isn't clear
about this. It's a guess as good as any other of the possible options,
so we could start with it and possibly fix it later, but could you try
to get clarification from Renesas on this ?
