Apologies for the rapid fire (I tend to be much more conservative when
resending series), but given that this series has a direct impact on
other projects (such as u-boot), I'm trying to converge as quickly as
possible.

This series aims at fixing a number of issues for the recently merged
Apple PCIe driver, all revolving around the mishandling of #PERST:

- we didn't properly drive #PERST, and we didn't follow the specified
  timings

- the DT had the wrong polarity, which has impacts on the driver
  itself

Hopefully, this should address all the issues reported so far.

* From v2:
  - Fixed DT
  - Fixed #PERST polarity in the driver
  - Collected Pali's ack on patch #1

Hi Bjorn,

this series is v5.16-rcX material for PCI fixes, can you pick patches 1,3
up please ?

Do you mind picking patch #2 as well? Or shall I route it somewhere else?

Thanks,

        M.
