The reason of not fixing this issue and reverting the patch instead is
this patch can't handle another case. It's not easy to handle multiple
gpios sharing one pin register. So this gpio range feature will be
implemented by other patches.

Drivers: pinctrl: remove __dev* attributes.

2013-01-03T23:57:02+00:00

CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

Merge tag 'driver-core-3.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

Pull driver core updates from Greg Kroah-Hartman:
 "Here's the large driver core updates for 3.8-rc1.

  The biggest thing here is the various __dev* marking removals.  This
  is going to be a pain for the merge with different subsystem trees, I
  know, but all of the patches included here have been ACKed by their
  various subsystem maintainers, as they wanted them to go through here.

  If this is too much of a pain, I can pull all of them out of this tree
  and just send you one with the other fixes/updates and then, after
  3.8-rc1 is out, do the rest of the removals to ensure we catch them
  all, it's up to you.  The merges should all be trivial, and Stephen
  has been doing them all in linux-next for a few weeks now quite
  easily.

  Other than the __dev* marking removals, there's nothing major here,
  some firmware loading updates and other minor things in the driver
  core.

  All of these have (much to Stephen's annoyance), been in linux-next
  for a while.

pinctrl: single: support gpio request and free

2012-11-21T07:55:27+00:00

Marvell's PXA/MMP silicon also match the behavior of pinctrl-single.
Each pin binds to one register. A lot of pins could be configured
as gpio.

GPIO range is defined as a child node of pinmux in .dtsi file. If those
pins are with the same gpio function configuration in the pinmux
register, they could be defined in the same GPIO range. For this new
child node, two properties are used.

reg =

pinctrl: single: dump pinmux register value

2012-11-15T14:11:07+00:00

Dump pinmux register value, not only function part in the pinmux
register.

Also fix the issue on caluclating pin offset. The last parameter
should be pin number, not register offset.
