Pull spi updates from Mark Brown:
 "Quite a lot of activity in SPI this cycle, almost all of it in drivers
  with a few minor improvements and tweaks in the core.

   - Updates to pxa2xx to support Intel Broxton and multiple chip selects.
   - Support for big endian in the bcm63xx driver.
   - Multiple slave support for the mt8173
   - New driver for the auxiliary SPI controller in bcm2835 SoCs.
   - Support for Layerscale SoCs in the Freescale DSPI driver"

An spi_driver does not need to set an owner, it will be populated by the
driver core.

Staging: iio: Remove exceptional & on function name

2015-10-13T17:11:03+00:00

In this file, function names are otherwise used as pointers without &.

A simplified version of the Coccinelle semantic patch that makes this
change is as follows:

// 
@r@
identifier f;

f(...) { ... }
@@
identifier r.f;
@@

- &f

staging: iio: resolver: replace iio_device_register by devm_iio_device_register

2015-10-04T07:31:07+00:00

Use devm_iio_device_register instead of iio_device_register when the remove
function is only used to call iio_device_unregister in order to ease the error path.
Since resource managed functions implicitly call unregister at driver detach also remove
iio_device_unregister

Staging: iio: Allow compile test of GPIO consumers if !GPIOLIB

2015-05-10T19:31:43+00:00

The GPIO subsystem provides dummy GPIO consumer functions if GPIOLIB is
not enabled. Hence drivers that depend on GPIOLIB, but use GPIO consumer
functionality only, can still be compiled if GPIOLIB is not enabled.

Relax the dependency on GPIOLIB if COMPILE_TEST is enabled, where
appropriate.

Merge tag 'iio-for-4.1a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next

First set of new drivers, cleanups and functionality for IIO in the 4.1 cycle.

New drivers
* CM3323 color sensor.
* MS5611 pressure and temperature sensor.

New functionality
* mup6050 - create mux clients for devices described via ACPI. The reasoning
     and approach taken in this patch are complex.  Basically there is no
     otherway of finding out what is there than by some esoteric look ups in
     the ACPI data.
* cm3232 - PM support
* itg3200 - suspend/resume support
* mcp320x - add more ADCs to the kconfig to reflect what the driver supports
     (this patch and the bindings got left behind when the support was added
      a while back).

Docs / utils
* ti-adc128s052 - DT bindings.
* mcp3422 - DT bindings.
* mcp320x - DT bindings
* ABI docs for event threshold scale attributes, in_magn_offset, proximity
  scan_element and thresh falling/rising values for accelerometers.  All
  elements long in use that have slipped by being explicitly documented.
* Tidy up the tools previously in drivers/staging/iio/Documentation and move
  them out to /tools/iio. Yet another move that should have happened long ago.
  This time Roberta Dobrescu did the leg work.  Thanks!

Core Cleanups
* Export userspace IIO headers.  We should have done the appropriate header
  splitting a long time ago. Thanks to Daniel for sorting this out.

* Refactor the registring of attributes for buffers to move all non-custom
  ones to a vector allowing easier additions to the current set in the future.

Driver Cleanups
* gpiod related cleanups.  Make use of the additional parameter to specify
  	initial direciton to avoid extra code.
* bmc150 - Various refactorings to reduce code repitition and prepare for
           hardware buffer support.  Some of these cleanups are good even
	   without the new functionality.
* kmx61 - direct use of index to an array avoiding a structure element which
          was always the index to an element in an array of that structure.
* vf610 - avoid incorrect type for return from wait_for_completion_timeout.
* gp2ap020a00f - use put_unaligned_le32 for slight code simplification.
* ade7754 - improve error handling including suppressing some build warnings.
* ade7759 - improve error handling including suppressing some build warnings.
* hmc5843 - Long line and indentation fixes. Also some constifying of various
      constant data.
* ade7854 - 80+ character line splitting.
* ad2s1210 - fix wrong printf format string.
* mxs-lradc - fix wrong printf format string.
* ade7954-i2c - code alignment fixes and other trivial but worthwhile bits.
* periodic rtc trigger - make the frequency type an unsigned int as it
  is always treated as such.
* jsa1212 - constify struct regmap_config as it is constant.
* ad7793 - typo in the MODULE_DESCRIPTION
* mma9551 - check gpiod_to_irq errors.  Note that this doesn't actually cause
    any trouble but is worth tidying up as obviously incorrect.
* mlx90614 - refactor the register symbols to make it clear which reads are to
    RAM not PROM.

Staging: iio: replace pr_* with dev_*

2015-03-18T10:21:33+00:00

dev_* is prefered over pr_* when appropriate device stuct is present.
This patch replace pr_err and pr_warn with its dev_ counterpart.
