Subject: [PATCH v3 0/3] PCI: apple: Assorted #PERST fixes
Date: Tue, 23 Nov 2021 18:06:33 +0000	[thread overview]
Message-ID: <20211123180636.80558-1-maz@kernel.org> (raw)

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
