Convert the PCI controller drivers to use GPIO agnostic API.
While at it, remove of_gpio.h leftover from some of the drivers.
In v2:
- combined previously sent patches into a series (Manivannan)
- added tags (Rob, Manivannan)
- converted iMX.6 driver (Manivannan)
- dropped leftover in aadvark drivers (Manivannan)
Andy Shevchenko (4):
PCI: aardvark: Remove unused of_gpio.h
PCI: dwc: Remove unused of_gpio.h
PCI: imx6: Convert to agnostic GPIO API
PCI: kirin: Convert to agnostic GPIO API

Small problem here. err message "unable to get reset gpio\n" will print
when -EPROBE_DEFER happen. EPROBE_DEFER is quite common when use i2c
expand gpio chip.

If i2c gpio-expander driver have not load when imx6_pcie probe, I supposed
devm_gpiod_get_optional() will return -EPROBE_DEFER,
if (IS_ERR(imx6_pcie->reset_gpiod)) should be true. then dev_err_probe()
will run and print "unable to get reset gpio\n" with error code
-EPROBE_DEFER.
driver framework will retry imx6_pcie probe again when a new device appear.
it may retry sevial times utill i2c gpio-expander driver probe success or
timeout.

-EPROBE_DEFER.
That's exactly the point of using dev_err_probe().

Please don't use GPIOD_ASIS even if the old code was using it.
For all 3 GPIOs in this driver, GPIOD_OUT_LOW flag should be used as the default
state is assert (considering the fact that the DT uses GPIO_ACTIVE_HIGH).

Please don't use GPIOD_ASIS even if the old code was using it.
For all 3 GPIOs in this driver, GPIOD_OUT_LOW flag should be used as the default
state is assert (considering the fact that the DT uses GPIO_ACTIVE_HIGH).

And if not? I believe we may not assume that all of DTBs around the globe put
the flags correctly. But I think you know much more about them than me, hence
I am okay to update this.
