[PATCH 0/2] Add HDMI support to iwg22d

[Fabrizio Castro]

Hello,

this series aims to add HDMI support to iWave RZ/G1E (R8A7745) board.
This series has been tested against renesas-devel-20171106-v4.14-rc8.

[PATCH 1/2] ARM: dts: r8a7745: Add DU support

[Fabrizio Castro]

Add du node to r8a7745 SoC DT. Boards that want to enable the DU
need to specify the output topology.
