The first patch is a small fix which is useful for the second one.
This version basically follows Fabio's suggestion to reimplement the
first version patch, using a regulator that can be backed by GPIO to
control the power to PCIe port.

Shawn Guo (2):
  PCI: histb: fix error path of histb_pcie_host_enable()
  PCI: histb: add an optional regulator for PCIe port power control

Hi Bjorn,

Did you get a chance to look at the series?

I cc'd Lorenzo, who is now taking care of this area.

If/when you repost this, please incorporate Rob's ack and capitalize
the first word of your summary ("Fix", "Add") to match the drivers/pci
convention.

Also, the original post used "PCI: hisi:", but here you use
"PCI: histb:".  It probably does make sense to distinguish
"hisi" from "histb", but I want it to be a conscious choice
so future patches can be consistent with it.

I suspect that using histb makes more sense but I will wait Shawn's
feedback on this, this series was on my radar anyway but thanks
for the flag up.

Yes, we want to distinguish the driver pcie-histb.c from pcie-hisi.c,
and will consistently use "PCI: histb:" for this driver.

Cool.  I will keep you posted on v3.

Thanks, Bjorn, Lorenzo.
