Hi Martin and Guido, I am trying to get MIPI DSI panel to work on an imx8mq-evk board. Here are the changes I did against linux-next 20200914 following what was done on imx8mq-librem5-devkit.dts: https://pastebin.com/raw/GXazRyNx The config I am using is this one: https://pastebin.com/raw/UGAjTQyg This is what I see in dmesg: [ 1.666974] mxsfb 30320000.lcd-controller: [drm:mxsfb_probe] *ERROR* failed to attach bridge: -517 [ 1.667309] sdhci-esdhc-imx 30b50000.mmc: Got CD GPIO [ 1.675977] mxsfb 30320000.lcd-controller: Cannot connect bridge: -517 [ 1.689620] mxsfb 30320000.lcd-controller: [drm:mxsfb_probe] *ERROR* failed to attach bridge: -517 [ 1.692019] mmc0: SDHCI controller on 30b40000.mmc [30b40000.mmc] using ADMA [ 1.698606] mxsfb 30320000.lcd-controller: Cannot connect bridge: -517 [ 1.711321] mmc1: SDHCI controller on 30b50000.mmc [30b50000.mmc] using ADMA [ 1.721418] mxsfb 30320000.lcd-controller: [drm:mxsfb_probe] *ERROR* failed to attach bridge: -517 [ 1.730422] mxsfb 30320000.lcd-controller: Cannot connect bridge: -517 Any ideas as to what I am missing?
