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:
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.
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
For you or the wider community?
