For HDMI output point of view,
as 1st step, it needs additional config. I attached it on this mail.
I know Geert don't like it, but I hope Ulrich can handle it in
formal version ;P
My main problem is that HDMI1 output (= from CN17) is broken
on this renesas-drivers version.
It doesn't have such issue on previous version.
renesas-drivers-2016-04-12-v4.6-rc3 : no problem
renesas-drivers-2016-04-26-v4.6-rc5 : HDMI1 output broken
This is log

Subject: [PATCH] arm64: defconfig: add VIDEO_RENESAS_FCP
DRM_RCAR_VSP requests VIDEO_RENESAS_VSP1, and VIDEO_RENESAS_VSP1 requests
VIDEO_RENESAS_FCP. But VIDEO_RENESAS_FCP is not set on defconfig.
This patch adds it. Otherwise kernel goes to Oops.
