Track full vc4-kms-v3d-pi4 support in Raspi 5.4 LTS kernel
As it stands, the initial Pi4 elements were merged & utilise the 'fake' vc4-fkms-v3d
shim dtb overlay as the full open source vc4-kms-v3d-pi4
was considered experimental going from 4.19 to 5.4 (more info https://github.com/raspberrypi/firmware/blob/master/boot/overlays/README#L2717 & https://www.raspberrypi.org/forums/viewtopic.php?t=269769) and various driver crashes were reported.
Whilst work continues to stabilise 5.4 linux & firmware it would be good to periodically track the refs to the corresponding branch heads, and see how the vc4-kms-v3d-pi4
overlay behaves/performs.
