Nikolaus Schaller" <hns@goldelico.com> Subject: [RFC 0/8] MIPS: CI20: add HDMI out support Date: Wed, 26 Feb 2020 20:12:52 +0100 [thread overview] Message-ID: <cover.1582744379.git.hns@goldelico.com> (raw) This patch series adds HDMI output to the jz4780/CI20 board. It is based on taking the old 3.18 vendor kernel and trying to achieve the same with modern DTS setup and new/modified drivers. Unfortunately, in this first RFC, only EDID and creation of /dev/fb0 are working. Also, HDMI hot plugging is detected. But there is no HDMI output signal. So some tiny piece seems to be missing to enable/configure the Synposys HDMI controller. We need help from the community to fix this. Note: device tree bindings are from 2015 and still seem to fit - except they are not in yaml format.
