[PATCH v3 0/5] Add Display support

[PATCH v3 0/5] Add Display support

[Biju Das]

This patch series aims to add display support for iWave G20D-Q7 board based on RZ/G1N.

This patch series is tested against linux-next

V1--> V2
	* Add DU support : Removed LVDS definition from r8a7743 DU node.
V2--> V3
	* Added LVDS support for both r8a7743 and r8a7744 SoC.

Biju Das (5):
  ARM: dts: r8a7743: Convert to new LVDS DT bindings
  dt-bindings: display: renesas: lvds: Document r8a7744 bindings
  drm: rcar-du: lvds: Add r8a7744 support
  ARM: dts: r8a7744: Add DU support
