This series brings up the HDMI output on the Debix Model A SBC. With support for the HDMI transmitter for the i.MX8MP SoC now merged[0], we can now enable the HDMI output on the Debix Model A SBC. The pinctrl values were blindly taken from the downstream BSP[1] and should be checked by someone who knows this platform better than myself. Also, with a 4K display there were a drm error with no output on the display, but this error did not occur with a 1080P display: imx-lcdif 32fc6000.display-controller: [drm] *ERROR* fbdev-dma: Failed to setup generic emulation (ret=-12) It would be interesting to see if this error is present for others on a different i.MX8MP device. I didn't have time to check this further and I assume the issue to be in the driver rather than specific to this SBC, so should not block this patch, but please correct me if I am wrong.
