Subject: [PATCH v1 0/1] Enable HDMI output support on the Debix Model A SBC
Date: Mon, 15 Apr 2024 12:41:26 +0100 [thread overview]
Message-ID: <20240415114135.25473-1-chris.obbard@collabora.com> (raw)
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.
