+++ help is needed: driver is not completely working and shows no output signal on the HDMI data and clock lanes +++ HPD is working and /dev/fb0 does appear +++ but there is no trigger to initialize the lcdc * add definition for second jz4780-lcdc * diverse fixes for yaml schema * make ingenic-drm driver compatible to ingenic,jz4780-lcd * converted existing ingenic,lcd.txt to ingenic,lcd.yaml - suggested by Paul Cercueil <paul@xxxxxxxxxxxxxxx> * removed blank line before MODULE_DEVICE_TABLE() macro - Paul Cercueil <paul@xxxxxxxxxxxxxxx> * added some missing Signed-off: * removed Zubair Lutfullah Kakakhel <Zubair.Kakakhel@xxxxxxxxxx> from the recipients list and Cc: since the address is no longer available. * removed "pinctrl: ingenic: add hdmi-ddc pin control group" from this patch series since it is already applied elsewhere (by Linus Walleij <linus.walleij@xxxxxxxxxx>) RFC V2 2020-02-28 19:19:40: * Converted .txt bindings to .yaml (by Sam Ravnborg <sam@xxxxxxxxxxxx> - big THANKS) RFC V1 2020-02-26 20:13:06: This patch series adds HDMI output to the jz4780/CI20 board. It is based on taking the old 3.18 vendor kernel as well as an earlier submission from 2015: https://lore.kernel.org/patchwork/patch/547872/ 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.
