[PATCH] arm64: dts: freescale: debix-som-a-bmb-08: Enable HDMI output

From: Kieran Bingham
Date: Tue Sep 16 2025 - 10:47:47 EST


Enable the HDMI output on the Debix SOM A board, using the HDMI encoder
present in the i.MX8MP SoC.

Enable and configure all nodes required for the HDMI port usage.

This replicates 4880ee1c9046 ("arm64: dts: imx8mp-debix-model-a: Enable
HDMI output") to support the Debix SOM as well.
