Linus,

Sorry about the resend, but i just realized i should have copied you
directly on the follow-up.

Please let me know what you think.
I do have a modified version of Boris' first patch addressing your original
comments which I am planning to submit if you it is still a valid idea.

Regards,
Benoit Parrot

As Felipe mentioned we do have several evm with IO-expander controlling
various mux. This feature would be very nice to have as we now have to
insert the board related gpio setting code in the pdata-quirks which
works temporarily but we are looking for an upstreamable solution.

I am leaning toward taking Boris patch set and reworking them given the
comments you already had, unless you have a better ideas in mind.

Benoit Parrot
