gpio: use dev_get_platdata()

2013-08-16T13:24:35+00:00

Use the wrapper function for retrieving the platform data instead of
accessing dev->platform_data directly.

gpio: em: Add pinctrl support

2013-07-21T15:24:41+00:00

Register the GPIO pin range, and request and free GPIO pins using the
pinctrl API. The pctl_name platform data member should be used by
platform devices to point out which pinctrl device to use.

Follows same style as "dc3465a gpio-rcar: Add pinctrl support",
by Laurent Pinchart, thanks to him.

gpio: em: Make use of devm functions

2013-03-27T15:05:09+00:00

Update the Emma Mobile GPIO driver to make use of devm
functions. This simplifies the error handling and makes
the code more compact.

gpio/em: Add Device Tree support

2013-03-06T01:12:26+00:00

Update the Emma Mobile GPIO driver to add DT support.

The patch simply adds a two-cell xlate function and
updates the probe code to allow configuration via DT
using the "ngpios" property plus OF id in the same
style as gpio-mvebu.c. The code is also adjusted to
use postcore_initcall() to force early setup.

gpio: em: Use irq_domain_add_simple() to fix runtime error

2013-02-14T16:44:37+00:00

Adjust the gpio-em.c driver to reconsider the pdata->irq_base
variable. Non-DT board code like for instance board-kzm9d.c
needs to operate of a static IRQ range for platform devices.

So this patch is updating the code to make use of the function
irq_domain_add_simple() instead of irq_domain_add_linear().

Fixes a EMEV2 / KZM9D runtime error caused by the following commit:
7385500 gpio/em: convert to linear IRQ domain

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

2012-12-11T21:13:55+00:00

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.
