[PATCH v5 00/14] PCI: Add support for Apple M1

From: Marc Zyngier
Date: Wed Sep 29 2021 - 12:39:10 EST


This is v5 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.

Very little has changed code wise (a couple of bug fixes). The series
however now carries a bunch of DT updates so that people can actually
make use of PCIe on an M1 box (OK, not quite, you will still need [2],
or whatever version replaces it). The corresponding bindings are
either already merged, or queued for 5.16 (this is the case for the
PCI binding).

It all should be in a state that makes it mergeable (yeah, I said that
last time... I mean it this time! ;-).

As always, comments welcome.

M.
