This series brings up the HDMI output on the Debix Model A SBC.
With support for the HDMI transmitter for the i.MX8MP SoC in mainline,
we can now enable the HDMI output on the Debix Model A SBC.
Changes in v2:
- Do not set SION (Software Input ON) bit in pinmux pin config register.
- Small changes to commit log/cover letter.
- v1: https://lore.kernel.org/linux-arm-kernel/20240415114135.25473-1-chris.obbard@collabora.com/

Enable the HDMI output on the Debix Model A SBC, using the HDMI encoder
present in the i.MX8MP SoC.
This has been tested with a generic 1080p HDMI display, along with a
smaller 1280x800 HDMI display.
