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.
