No I'll have to scrap this topic branch, as it does not compile.

Analysing the problem I see that part of the reason why it does
not compile is that it is adding stuff referencing the global
numberspace, like biasing.

Which is pinctrl business. So the proper feedback is that it
should be rewritten to use pinctrl.

Which is in the works.

So the plan is to mail out an all-in-one pinctrl replacement
patch instead, deleting the old AB8500 GPIO driver and
replacing it fully with a pinctrl driver.

Yours,
Linus Walleij
