[PATCH v2 0/5] Add DU, VSPD and FCPVD support for RZ/T2H and RZ/N2H SoCs

[Prabhakar]

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@xxxxxxxxxxxxxx>

Hi all,

This patch series adds support for the Display Unit (DU) on the RZ/T2H
(r9a09g077) and RZ/N2H (r9a09g087) SoCs. The DU is a key component of
the display pipeline, responsible for driving the display output.
The patches include:
- Adding VSPD and FCPVD nodes to the SoC DTSI files for both RZ/T2H
  and RZ/N2H.
- Adding the DU node to the SoC DTSI files, including clock and
  interrupt configurations.
- Adding DT overlay support for enabling the DU/LCDC pipeline on the
  RZ/T2H and RZ/N2H evaluation kits when fitted with a CN15/CN20
  ADV7513 HDMI transmitter.

Note,
- DU driver patches have been merged into-next.
- FCP/VSP patches have been posted separately and are in Laurent's tree.

- Patches apply on top of renesas-devel/renesas-dts-for-v7.3 (e0c6913891b1) branch.

v1->v2:
- Fixed typo in makefile for ARCH_R9A09G087
- Explicitly disabled the LED7 and key-1 in the overlay
- Dropped comment about DSW5[3] in patch#5
- Updated commit message in patch#5
- Dropped internal RB tag in patch#3

Cheers,
