Commit Message

Biju Das Oct. 2, 2024, 5:04 p.m. UTC 
commit cc49fcd0bc2db23489a87f6fa17119a76b70ec6b upstream.

Enable the Display Unit and link with the HDMI add-on board connected
to the parallel connector on the RZ/G2UL SMARC EVK by using a Device
Tree overlay.

DT overlay changes are different compared to mainline. So ported the
changes without using overlay.
