Subject[PATCH v2] arm64: dts: renesas: r8a77995-draak: Enable DU
Date
From: Kieran Bingham <kieran.bingham+renesas@ideasonboard.com>

Enable the DU, providing only the VGA output for now.

Signed-off-by: Kieran Bingham <kieran.bingham+renesas@ideasonboard.com>
Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

Just a v2 update to fix the PFC name, and collect Laurent's RB tag. The
remainder of the series will likely be postponed due to dependencies on LVDS
changes etc.

v2:
- Update du_dot_clk_0 name to match Ulrich's PFC configuration.
