I realised after I sent the tags on v3 that I'd made a mistake: There's a
slightly awkward to test bug in the v3 implementation. I followed up on v3 with
this:

	https://lkml.org/lkml/2017/8/16/905

And Yong sent out a corresponding v4:

	https://patchwork.ozlabs.org/patch/802946/

I see you've pushed Yong's v3 in pinctrl/devel - can we revert/remove that and
apply v4?

Sorry for the confusion.

Andrew
