pinctrl: Pass all configs to driver on pin_config_set()

2013-08-28T11:34:41+00:00

When setting pin configuration in the pinctrl framework, pin_config_set() or
pin_config_group_set() is called in a loop to set one configuration at a time
for the specified pin or group.

This patch 1) removes the loop and 2) changes the API to pass the whole pin
config array to the driver.  It is now up to the driver to loop through the
configs.  This allows the driver to potentially combine configs and reduce the
number of writes to pin config registers.

All c files changed have been build-tested to verify the change compiles and
that the corresponding .o is successfully generated.

drivers/pinctrl: don't check resource with devm_ioremap_resource

2013-08-07T20:29:21+00:00

devm_ioremap_resource does sanity checks on the given resource. No need to
duplicate this in the driver.

Pull pin control changes from Linus Walleij:

- A large slew of improvements of the Genric pin configuration support,
and deployment in four different platforms: Rockchip, Super-H PFC,
ABx500 and TZ1090. Support BIAS_BUS_HOLD, get device tree parsing
and debugfs support into shape.

- We also have device tree support with generic naming conventions for
the generic pin configuration.

- Delete the unused and confusing direct pinconf API. Now state
transitions is *the* way to control pins and multiplexing.

- New drivers for Rockchip, TZ1090, and TZ1090 PDC.

- Two pin control states related to power management are now handled in
the device core: "sleep" and "idle", removing a lot of boilerplate
code in drivers. We do not yet know if this is the final word for
pin PM, but it already make things a lot easier to handle.

- Handle sparse GPIO ranges passing a list of disparate pins, and
utilize these in the new BayTrail (x86 Atom SoC) driver.

- Make the sunxi (AllWinner) driver handle external interrupts.

- Make it possible for pinctrl-single to handle the case where several
pins are managed by a single register, and augment it to handle sleep
modes.

- Cleanups and improvements for the abx500 drivers.

- Move Sirf pin control drivers to their own directory, support
save/restore of context and add support for the SiRFatlas6 SoC.

- PMU muxing for the Dove pinctrl driver.

- Finalization and support for VF610 in the i.MX6 pinctrl driver.

- Smoothen out various Exynos rough edges.

- Generic cleanups of various kinds.

pinctrl: u300: remove unnecessary platform_set_drvdata()

2013-06-16T09:56:48+00:00

The driver core clears the driver data to NULL after device_release
or on probe failure, since commit 0998d0631001288a5974afc0b2a5f568bcdecb4d
(device-core: Ensure drvdata = NULL when no driver is bound).
Thus, it is not needed to manually clear the device driver data to NULL.

This adds a simple device tree compat string for the U300 pin

a resource and everything works fine.

pinctrl: Convert to devm_ioremap_resource()

2013-01-22T19:41:57+00:00

Convert all uses of devm_request_and_ioremap() to the newly introduced
devm_ioremap_resource() which provides more consistent error handling.

devm_ioremap_resource() provides its own error messages so all explicit
error messages can be removed from the failure code paths.

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

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.
