[PATCH v4 2/4] arm64: dts: renesas: r8a779a0: Add DSI encoders

From: Kieran Bingham
Date: Fri Nov 26 2021 - 05:02:14 EST


Provide the two MIPI DSI encoders on the V3U and connect them to the DU
accordingly.

Reviewed-by: Laurent Pinchart <laurent.pinchart@xxxxxxxxxxxxxxxx>
Signed-off-by: Kieran Bingham <kieran.bingham+renesas@xxxxxxxxxxxxxxxx>
---
v2
- Fixup indentation

v3
- Fix the clock references
- Fixup dsi1 as well

-v4:
- Use the correct pll clocks.


This is still pending approval/integration of the DSI encoder bindings
