I had a look at the simple panel driver and it's not enough for the display in the p4note. I asked Marek in IRC whether it's ok to have this in a separate patch set to have a fully working display and he agreed. > Best regards, > Krzysztof

However in such case I would simply remove the whole fimd node now. Without a panel it is a bit useless imho. With a proper panel driver you will also get rid of the timings subnode, so there is no point adding it now. Best regards

The display is working but missing proper GPIO handling and the possibility to adjust brightness right now. As it is connected to the LCD power domain, it's still turning on and off as expected as it is setup by the bootloader. I know this isn't a great solution, but I'm already working on the LCD driver. Not sure when it will be done though. The display timings are read in exynos_drm_dpi.c in the exynos_dpi_probe method. As far as I understand, you can either provide the timings in the fimd node itself or in a connected panel. If this is not intended, I can of course remove the configuration. > Best regards > > -- > Marek Szyprowski, PhD > Samsung R&D Institute Poland > Cheers Martin

If it works already then imho we can keep it for now and then adjust later when the proper panel driver is ready. Best regards
