[PATCH] ARM: dts: Drop am335x-base0033 devicetree
Posted by Kory Maincent 2 weeks, 1 day ago 
From: "Kory Maincent (TI.com)" <kory.maincent@bootlin.com>

Remove the am335x-base0033 devicetree as it has been non-functional since
2017 (Linunx v4.14) when the ti,tilcdc,slave binding was removed. The HDMI
output on this board has been broken for over 8 years without any reported
issues or attempts to fix it, indicating this devicetree is no longer in
active use.

I don't think this is maintained at all. I personally don't have
access to the hardware, so
