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

From: Kieran Bingham <kieran.bingham+renesas@ideasonboard.com>
Date: 2021-11-26 10:02:14
Also in: linux-renesas-soc, lkml
Subsystem: arm/risc-v/renesas architecture, the rest · Maintainers: Geert Uytterhoeven, Magnus Damm, Linus Torvalds

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

Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

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
