Hi!
This adds D3 support to the DU and LVDS drivers, not including LVDS PLL support.
It also adds LVDS encoders to the D3 device tree, and LVDS decoder, HDMI encoder and HDMI output connector to the Draak device tree.
In theory that should be good enough to provide HDMI output on the Draak board, but in practice the lack of LVDS PLL support prevents generation of close-enough dot clock frequencies.
This series is based on renesas-drivers-2018-05-02-v4.17-rc3 and requires Jacopo's "drm: bridge: Add thc63lvd1024 LVDS decoder driver" patch.
As HDMI output isn't functional yet this is difficult to test. Could you add support for the VGA output (using the DU DPAD) in v2 of the patch series ? VGA should work without LVDS PLL support as the clock frequency requirements are not as strict as for HDMI.
