Hi Marc,

I'm afraid this commit breaks booting my rk3399 device.

I bisected the problem to this patch merged as [1]. I'm testing on a
Scarlet device and I'm using the unmodified upstream
rk3399-gru-scarlet-inx.dtb for my tests.

The problem I'm experience is a black screen after the bootloader and
the device is none responsive over the network. I have no serial console
to this device so I'm afraid I can't tell you if there is anything
useful on to aid debugging there.

If I try to test one commit earlier [2] the system boots as expected and
everything works as it did for me in v5.8 and earlier. I have worked
little with this device and have no clue about what is really on the PCI
buss. But running from [2] I have this info about PCI if it's helpful,
please ask if somethings missing.

Please see the thread at [1]. The problem was reported a few weeks back
by Samuel, and I was expecting Rob and Lorenzo to push a fix for this.

Rob, Lorenzo, any update on this?

M.
