drivers/pinctrl/pinctrl-nomadik.c: drop devm_kfree of devm_kzalloc'd data

2012-08-07T12:34:12+00:00

devm_kfree should not have to be explicitly used.

The semantic patch that fixes this problem is as follows:
(http://coccinelle.lip6.fr/)

//

expression x,d;

x = devm_kzalloc(...)
...
?-devm_kfree(d,x);

pinctrl/pinctrl-u300: remove unneeded devm_kfree call

2012-08-04T22:24:15+00:00

the allocated memory will be destroyed at the driver unload time,
automatically if driver uses the devm_ functions, so no need of
doing devm_kfree at the error path

pinctrl: mxs: register driver at postcore_initcall time

2012-08-04T22:24:15+00:00

It's not so usual, but there are still some cases which require pinctrl
driver function at arch_initcall time.  So register imx23 and imx28
pinctrl driver at postcore_initcall time.

Pull pin control changes from Linus Walleij:
 "These are the accumulated pin control patches for v3.6:
   - Various cleanups to the U300 driver
   - Refactor the pin control core to automatically remove any GPIO
     ranges when the drivers are removed, instead of having the drivers
     do this explicitly.
   - Add a function for registering a batch of GPIO ranges.
   - Fix a number of incorrect but non-regressive error checks.
   - Incremental improvements to the COH901, i.MX and Nomadik drivers
   - Add a one-register-per-pin entirely Device Tree-based pin control
     driver from Tony Lindgren."

Pull arm-soc device tree description updates from Arnd Bergmann:
 "This branch contains two kinds of updates: Some platforms in the
  process of getting converted to device tree based booting, and the
  platform specific patches necessary for that are included here.

  Other platforms are already converted, so we just need to update the
  actual device tree source files and the binding documents to add
  support for new board and new drivers.

  In the future we will probably separate those into two branches, and
  in the long run, the plan is to move the device tree source files out
  of the kernel repository, but that has to wait until we have completed
  a much larger portion of the binding documents."

Fix up trivial conflicts in arch/arm/mach-imx/clk-imx6q.c due to newly
added clkdev registers next to a few removed unnecessary ones.

pinctrl: Add one-register-per-pin type device tree based pinctrl driver

2012-07-14T20:33:08+00:00

Add one-register-per-pin type device tree based pinctrl driver.

This driver has been tested on omap2+ series of processors,
where there is either an 8 or 16-bit padconf register for each pin.
Support for other similar pinmux controllers can be added.

pinctrl: pinctrl-imx6q: add missed mux function for USBOTG_ID

2012-07-14T20:32:10+00:00

The original pin registers table is derived from u-boot mainline,
but somehow it was found missing some mux functions for USBOTG_ID.
We added it at the bottom by following the exist pin function ids,
then it will not break the exist using of pin function id in dts file.
