Subject: [PATCH v3 0/3] PCI: apple: Assorted #PERST fixes
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
