spi: expose master transfer size limitation.

2016-01-05T16:33:54+00:00

On some SPI controllers it is not feasible to transfer arbitrary amount
of data at once.

When the limit on transfer size is a few kilobytes at least it makes
sense to use the SPI hardware rather than reverting to gpio driver.

The protocol drivers need a way to check that they do not sent overly
long messages, though.

spi: add spi_message_init_no_memset to avoid zeroing the spi_message

2015-12-12T23:05:18+00:00

In the spi_loopback_test driver there is the need to initialize
a spi_message that is filled with values from a static structure.

Applying spi_message_init to such a prefilled structure results in
all the settings getting reset to zero, which is not what we want.
Copying each field of spi_message separately instead always includes
the risk that some new fields have not been implemented in the copying
code.

So here we introduce a version of spi_message_init called
spi_message_init_no_memset that does not fill the structure
with zero first, but only initializes the relevant list_heads.

spi: Uninline spi_unregister_device()

2015-12-01T18:50:11+00:00

Uninline spi_unregister_device() in preparation of adding more code to
it. Add kerneldoc documentation while we're at it.

Merge tag 'armsoc-cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

2015-11-10T22:48:36+00:00

Pull ARM SoC cleanups from Olof Johansson:
 "Again we have a sizable (but not huge) cleanup branch with a net delta
  of about -3k lines.

  Main contents here is:

   - A bunch of development/cleanup of a few PXA boards
   - Removal of bockw platforms on shmobile, since the platform has now
     gone completely multiplatform.  Whee!
   - move of the 32kHz timer on OMAP to a proper timesource
   - Misc cleanup of older OMAP material (incl removal of one board
     file)
   - Switch over to new common PWM lookup support for several platforms

  There's also a handful of other cleanups across the tree, but the
  above are the major pieces"

spi: Add THIS_MODULE to spi_driver in SPI core

2015-10-28T01:30:12+00:00

Add spi_register_driver helper macro that adds THIS_MODULE to
spi_driver for the registering driver. We rename and modify
the existing spi_register_driver to enable this.
