Subject: [PATCH v3 3/3] arm64: dts: renesas: r8a779a0: falcon-cpu: Add DSI display output

From: Kieran Bingham <[email protected]>

Provide the display output using the sn65dsi86 MIPI DSI bridge

Reviewed-by: Laurent Pinchart <[email protected]>

v3:
- Fix the voltage regulator values
- No longer override the clocks
- use clk-x6 as clock node name
