mmc-pwrseq-simple supports multiple reset/enable gpios (by listing

on which value they need to be to activate things).

It also supports listing clocks which need to be enabled. I think
that it may be a good idea to use this to also enable the bluetooth
bits of the ap6210 module on the cubietruck. I know that the
actual bt is interfaced over an uart, and we really should have
a mechanism to enable/disable it separately, but for not this seems
like a good way to get bluetooth to work.

We should ofcourse add a comment to the dts file that this is not a
100% ideal solution, but other then that I think this should work
nicely. Maxime would enabling the bluetooth bits of this sdio
module via mmc-pwrseq be acceptable to you?

As long as we have some comment on top, yep.

ChenYu if Maxime acks this solution I hope you can write a patch for
this, since you've been working on the bluetooth support before.

Note that I'm in holidays starting today. I plan on doing my
pull-requests for 4.3 later today, and will probably not be able to
merge any patches during the next two weeks, which mean that your
mmc-power seq patch for the cubietruck was probably the last one I was
merging for the 4.3 merge window.
