[PATCH v2 1/2] ARM: dts: r8a7743: Add DU support

[Fabrizio Castro]

Add du node to r8a7743 SoC DT. Boards that want to enable the DU
need to specify the output topology.

[PATCH v2 2/2] ARM: dts: iwg20d-q7-dbcm-ca: Add HDMI video output

[Fabrizio Castro]

Although there is a HDMI connector on the q7 carrier board it is not
connected to the RZ/G1M SoC. One must use the HDMI connector on the
camera daughter board.

This patch adds support for this connector.
