Add the QSPI controller node and describe the attached SPI NOR flash
(Winbond W25Q64FWSSAQ).
Add a corresponding vendor flash partition layout.

Enable the DWC3 USB 3.0 controller, its associated combo_phy (USB 3 PHY)
and usbphy2 (USB 2 PHY) on the MusePi Pro board.
The board uses a VLI VL817 hub, providing four ports.

are routed to the M.2 M-key connector and to the PCIe slot.

Allow serial output with the same uboot/opensbi settings so the
console works without providing a cmdline.

Andre,
Thanks for pushing this new version, overall, this series looks good to me,
Although there are few quite trivial issues, which I could help to fix it while
applying, let's give community some time to test and review..
P.S I haven't run it on musepi board, but trust you tested all functions..

alright, and sorry, my git send-email flow is a bit rusty, didn't notice those issues...

I tested the added devices except nvme as I don't have one connected.
But I do have a pci card in there, which works just fine, so generally speaking pcie works and I'd assume/hope nvme would too ;)
