Subject: Re: pinctrl-icelake: driver writes to wrong offsets?

Good bug hunting in this thread!

Please see if you can use libgpiod or the tools from the kernel
tools/gpio directory to test GPIO lines, I usually use that since
the global GPIO numberspace only constantly confuse me.

Especially when there is a really many many GPIOs the local
numberspace and the global GPIO numberspace approach the
same values and I get totally lost sometimes.
