      Drivers: iio: remove __dev* attributes. · fc52692c
      由 Greg Kroah-Hartman 提交于 
      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, 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.

      iio: ad7476: Add support for the ad7091r · 87c5b10f
      由 Lars-Peter Clausen 提交于 
      Add support for the ad7091r 12 bit ADC to the ad7476 driver. Although the
ad7091r is not really related to any of the other devices supported by this
driver, luckily for us there are not so many ways (which are not totally insane)
how sampling a single channel ADC via SPI can be implemented and support for the
ad7091r can be added to the driver with just a few adjustments.

The ad7091r requires an external "conversion start" pulse to start a sample
conversion. After the conversion has finished the result can be read via SPI. We
depend on a IIO trigger to generate this signal, as a result only sampling in
buffered mode and not in manual mode is available.

      staging:iio:ad7476: Fix off by one error for channel shift · cb75f233
      由 Lars-Peter Clausen 提交于 
      The datasheet is a bit confusing about this. It says that a dataword has 4
leading zeros, but the first zero is already put on the bus when CS is pulled
low and the second zero is put on the bus on the first leading edge of SCLK, so
when the first bit is sampled on the first trailing edge it will sample what the
datasheet refers to as the second leading zero. Subsequently we only see 3
leading zeros in the 16 bit dataword and the result we get is shifted to the
left by one bit. Fix this by adjusting the channel shift by 1.

      staging:iio: Streamline API function naming · 7cbb7537
      由 Lars-Peter Clausen 提交于 
      Currently we use two different naming schemes in the IIO API, iio_verb_object
and iio_object_verb. E.g iio_device_register and iio_allocate_device. This
patches renames instances of the later to the former. The patch also renames allocate to
alloc as this seems to be the preferred form throughout the kernel.

In particular the following renames are performed by the patch:
	iio_put_device -> iio_device_put
	iio_allocate_device -> iio_device_alloc
	iio_free_device -> iio_device_free
	iio_get_trigger -> iio_trigger_get
	iio_put_trigger -> iio_trigger_put
	iio_allocate_trigger -> iio_trigger_alloc
	iio_free_trigger -> iio_trigger_free

The conversion was done with the following coccinelle patch with manual fixes to
comments and documentation.

      staging:iio: Add missing MODULE_DEVICE_TABLE and MODULE_ALIAS · 55e4390c
      由 Lars-Peter Clausen 提交于 
      Quite a few iio drivers provide no MODULE_DEVICE_TABLE or MODULE_ALIAS or only
provide a MODULE_ALIAS while they have support for multiple device ids. This
prevents auto module loading from working correctly.

This patch fixes it by adding the missing MODULE_DEVICE_TABLEs and
MODULE_ALIAS'.

      staging:iio:treewide only use shared to decide on interfaces · c8a9f805
      由 Jonathan Cameron 提交于 
      Internally the fact that say scale is shared across channels is
actually of remarkably little interest.  Hence lets not store it.
Numerous devices have weird combinations of channels sharing
scale anyway so it is not as though this was really telling
us much. Note however that we do still use the shared sysfs
attrs thus massively reducing the number of attrs in complex
drivers.

Side effect is that certain drivers that were abusing this
(mostly my work) needed to do a few more checks on what the
channel they are being queried on actually is.

This is also helpful for in kernel interfaces where we
just want to query the scale and don't care whether it
is shared with other channels or not.

      staging:iio: Do not use bitmasks for channel info addresses · 924f8a21
      由 Lars-Peter Clausen 提交于 
      Currently the iio framework uses bitmasks for the address field of channel info
attributes. This is for historical reasons and no longer required since it will
only ever query a single info attribute at once. This patch changes the code to
use the non-shifted iio_chan_info_enum values for the info attribute address.

      staging:iio: header reorganization · af5046af
      由 Jonathan Cameron 提交于 
      Issue brought up by Lars-Peter Clausen. This is a varient of what
he suggested.

io/iio.h for driver stuff (has to include types.h)
	Sub files for the bits drivers may or may not use
	iio/sysfs.h
	iio/buffer.h (contents of current buffer_generic.h)
	(obviously anything offering events will need events.h as well)
iio/types.h for the enums that matter to both
	iio_chan_type, iio_modifier
iio/events.h for the event code stuff
	IIO_EVENT_CODE and friends.  + everything in chrdev.h  So this
	is the stuff that userspace cares about.
	Also include iio_event_type, iio_event_direction

Thus iio drivers include iio.h + as required
events.h
sysfs.h
buffer.h

in kernel users (once that interface is merged) will need inkern.h
which will pull in types.h

Userspace will need just events.h (which pulls in types.h) to get
everything they need to know about.  Buffer userspace access doesn't
currently need any core defines. All information about the data
format is passed through sysfs.
