After collecting some dts nodes i found out that hdmi is missing vop2 driver in mainline.
There is a vendor repo containing this driver based on 4.19
I currently try to add this driver to 5.15,but it’s huge…i already disabled hdr part as i guess it’s not needed. Maybe anyone can help here and can sort out some more?
Vop2 driver is currently disabled in Makefile to allow building kernel without hdmi support.
For compile tests (currently many errors) just revert this.if it is compilable,then still some things are missing because i add many new fields in existing and new structs which may need handling in mainline code.
