[v1,1/1] PCI: dwc: Remove unused of_gpio.h

of_gpio.h is deprecated and subject to remove.
The driver doesn't use it, simply remove the unused header.

What about the rest?

drivers/pci/controller/dwc/pcie-kirin.c
drivers/pci/controller/dwc/pci-imx6.c

There is also one non-dwc driver:

drivers/pci/controller/pci-aardvark.c

It is better to remove it from all PCI drivers in a single patch.

Have you chance to look at them?

Keyword: non-dwc.
This patch is for DesignWare controllers that confirmed not using the header.

I disagree on this. These are different drivers and even inside DesignWare not
all of them can be converted with a simple change like this one.

That said, please consider applying this one as is.

Ok. I failed to spot the usage of of_get_named_gpio() in both drivers. But you
already submitted a patch to convert kirin last year [1], and that didn't get
any love from the maintainers. Could you please respin? Perhaps convert imx6
also?

Since this is just a header removal I thought you can just send a single patch
for these drivers since there is nothing special that warrants a separate patch
for aardvark (both are inside the drivers/pci/ hierarchy).

But anyway, I wouldn't press for it.

I can give my R-o-b tag, but Lorenzo or Krzysztof will apply this.
