I figured as much, I had looked at the 4.19.y branch as I figured that's where the initial bits would be but I hadn't seen anything that stood out :-/ I was looking through the DT compatible strings from bcm2711-rpi-4-b.dtb and worked out the issues with the PCIe issue, I figured there was either a new driver or enablement to one of the other broadcom drivers, most of the rest looked like fairly generic Arm IP or exisiting broadcom bits so my guess would there would be DT plus probably some enablement bits for the new SoC to find. > Without a real datasheet with register documentation this isn't fun ...
