After discussing the matter with Laurent Pinchart it turned out that using ti,tilcdc,panel was wrong and we should go with the new simple-vga-dac driver proposed by Maxime Ripard and currently being reviewed. The da850-lcdk board on which I'm working has a THS8135 video DAC for which the new driver seems to be best suited and we'll be able to query the connected display for supported modes instead of hardcoding them in the dt as is needed for the panel driver. In the meantime I'm posting two patches based on Karl Beldan's previous work that can already be merged. The first one adds OF_DEV_AUXDATA entry to da8xx-dt.c. I changed the compatible string to the new one we're introducing in the tilcdc driver. The second adds the lcd pins and the display node to da850.dtsi. As suggested by Sekhar: I moved the pins node, which was previously in da850-lcdk.dts, to da850.dtsi. I also squashed Karl's two patches and removed the panel node. Tested on a da850-lcdk with an LCD display connected over VGA with two patches already posted to the drm mailing list: drm: tilcdc: add a da850-specific compatible string drm: tilcdc: add a workaround for failed clk_set_rate() and some additional work-in-progress/hacks on top of that.
