as far as i know there isn't any upstream branch. Some of the RPi 4
stuff has been prepared for upstream (usually BCM2711 = downstream,
BCM2838 = upstream), but are buried in the rpi-4.19 branch.

Looks at this for example:

https://github.com/raspberrypi/linux/commits?author=pelwell

But there are also lot of hacks. Currently the biggest part on Kernel
side is the PCIe driver which isn't upstreamed yet. Another problem is
that there is no U-Boot support yet.

Without a real datasheet with register documentation this isn't fun ...
