Subject: [GIT PULL] pin control changes for 3.3
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Hi Linus,
these are the pinctrl changes I've stacked up for 3.3.
The only bigger change is the addition of a pin
configuration API. This makes it possible to, well, config
stuff on pins. Usually this tends to be things like biasing
(pull-up, pull-down), drive strength, schmitt-triggering,
drive mode (open collector/open drain) etc.
We haven't yet merged any users of this interface, but these
can be expected in the next merge window.
Apart from that it is basically it's a bunch of refinements
where especially Stephen Warren deserves credit for
straightening out some design issues in the stuff merged
in 3.2.
Myself I've mostly renamed stuff, moved the COH901 driver
over from the GPIO subsystem (it's a copuled twin unit
with the U300 pin controller actually).
I was close to merging the PXA pin controller code for this
set, increasing the users from two to three platforms, but
I've decided to be conservative this time. We have a number
of potential platforms cooking so next time there may be
some serious migration to this subsystem.
Most stuff has been maturing in linux-next for a while
except the two top commits from Chanho Park which are
essentially fixes and would be -rc material anyway.
Please pull it in.
The following changes since commit caca6a03d365883564885f2c1da3e88dcf65d139:
