[PATCH v4 00/10] PCI: Add support for Apple M1

[Marc Zyngier <maz@kernel.org>]

This is v4 of the series adding PCIe support for the M1 SoC. Not a lot
has changed this time around, and most of what I was saying in [1] is
still valid.

The most important change is that the driver now probes for the number
of RID-SID mapping registers instead of assuming 64 entries. The rest
is a bunch of limited cleanups and minor fixes.

This should now be in a state that makes it mergeable, although I
expect that some of the clock bits may have to be adapted (I haven't
followed the recent developments on that front).

As always, comments welcome.
