Recent changes to the DT PCI bus parsing made it mandatory for
device tree nodes describing a PCI controller to have the
'device_type = "pci"' property for the node to be matched.
Although this follows the letter of the specification, it
breaks existing device-trees that have been working fine
for years. Rockchip rk3399-based systems are a prime example
of such collateral damage, and have stopped discovering their
PCI bus.
In order to paper over it, let's add a workaround to the code
matching the device type, and accept as PCI any node that is
named "pcie",
A warning will hopefully nudge the user into updating their
DT to a fixed version if they can, but the incentive is
obviously pretty small.
Fixes: 2f96593ecc37 ("of_address: Add bus type match for pci ranges parser")

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?

The fix is in Bjorn's tree[1].
Bjorn, going to send this to Linus before v5.9 is out?

Definitely, thanks for the reminder. I'm assuming the fix in question
is https://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci.git/commit/?h=for-linus&id=e338eecf3fe79054e8a31b8c39a1234b5acfdabe
