Hi! This implements HDMI output support for the Renesas R8A7795 (H3) SoC and Salvator-X board. It is based on mainline v4.9-rc4 and depends on Geert's "[PATCH v2 0/7] soc: renesas: Identify SoC and register with the SoC bus" series.
It fixes two major issues in the previous RFC series: 1. It uses soc_device_match() to distinguish chip revisions instead of accessing the product register directly. 2. It describes the Gen3 HDMI encoder devices in a sane manner in the device tree, which also eliminates many contortions in the driver code. The "drm: bridge/dw_hdmi: add dw hdmi i2c bus adapter support" patch has been updated to version 6, and some minor non-essential parts (such as support for additional pixel formats) have been split off, to be addressed later. For testing, use the defconfig and enable CONFIG_VIDEO_RENESAS_VSP1, CONFIG_DRM_RCAR_VSP and CONFIG_DRM_DW_HDMI.
