I have queued up the above patches for v4.3.

As the above patches are sh-pfc patches they would typically
be steered through Linus's tree via Laurent. If they wish
to take that path then I'm happy for this to be attached:

Acked-by: Simon Horman <horms+renesas@verge.net.au>

FWIW the above path is the one that the removal of mackerel/sh7372 took.

Alternatively, I am happy to take the above sh-pfc patches through
my tree but I would like to do so with an Ack from at least Linus.

I didn't CC Linus and linux-gpio at this stage yet, to prevent the pfc
patches from getting applied prematurely.
But things have gone more smoothly (esp. w.r.t. board staging) than expected,
which is always pleasant.

I can resend later, I have a few more areas of sh73a0/r8a7740 cleanup
outside arch/arm/mach-shmobile waiting anyway...

Thanks!

I'm happy with whatever timing you think is best.

I'm fine with both. I think it would be easier to applied them through your 
tree if Linus is fine with that. Those patches shouldn't generate any 
conflict.

I would prefer to take these four into the pin control tree when you
consider them finished as there is obviously more PFC stuff coming
for this next kernel cycle and I want to avoid collisions and keep
things together. Will you send them to me separately?

OK, I will send them your way.

I think at this point we're quite sure the sh73a0/r8a7740 removal will hit v4.3.
This does mean sh73a0/r8a7740-legacy will be broken in pinctrl/for-next,
but we don't care, as the support is gone in -next anyway.
