Greg Kroah-Hartman 3ffdea3fec First round of new drivers, functionality and cleanups for IIO in the 3.13 cycle
A number of new drivers and some new functionality + a lot of cleanups
 all over IIO.
 
 New Core Elements
 
 1) New INT_TIME info_mask element for integration time, which may have
    different effects on measurement noise and similar, than an amplifier
    and hence is different from existing SCALE.  Already existed in some
    drivers as a custom attribute.
 
 2) Introduce a iio_push_buffers_with_timestamp helper to cover the common
    case of filling the last 64 bits of data to be passed to the buffer with
    a timestamp.  Applied to lots of drivers. Cuts down on repeated code and
    moves a slightly fiddly bit of logic into a single location.
 
 3) Introduce info_mask_[shared_by_dir/shared_by_all] elements to allow support
    of elements such as sampling_frequency which is typically shared by all
    input channels on a device.  This reduces code and makes these controls
    available from in kernel consumers of IIO devices.
 
 New drivers
 
 1) MCP3422/3/4 ADC
 
 2) TSL4531 ambient light sensor
 
 3) TCS3472/5 color light sensor
 
 4) GP2AP020A00F ambient light / proximity sensor
 
 5) LPS001WP support added to ST pressure sensor driver.
 
 New driver functionality
 
 1) ti_am335x_adc Add buffered sampling support.
    This device has a hardware fifo that is fed directly into an IIO kfifo
    buffer based on a watershed interrupt.  Note this will act as an example
    of how to handle this increasingly common type of device.
    The only previous example - sca3000 - take a less than optimal approach
    which is largely why it is still in staging.
    A couple of little cleanups for that new functionality followed later.
 
 Core cleanups:
 
 1) MAINTAINERS - Sachin actually brought my email address up to date because
    I said I'd do it and never got around to it :)
 
 2) Assign buffer list elements as single element lists to simplify the
    iio_buffer_is_active logic.
 
 3) wake_up_interruptible_poll instead of wake_up_interruptible to only wake
    up threads waiting for poll notifications.
 
 4) Add O_CLOEXEC flag to anon_inode_get_fd call for IIO event interface.
 
 5) Change iio_push_to_buffers to take a void * pointer so as to avoid some
    annoying and unnecessary type casts.
 
 6) iio_compute_scan_bytes incorrectly took a long rather than unsigned long.
 
 7) Various minor tidy ups.
 
 Driver cleanups (in no particular order)
 
 1) Another set of devm_ allocations patches from Sachin Kamat.
 
 2) tsl2x7x - 0 to NULL cleanup.
 
 3) hmc5843 - fix missing > in MODULE_AUTHOR
 
 4) Set of strict_strto* to kstrto* conversions.
 
 5) mxs-lradc - fix ordering of resource removal to match creation
 
 6) mxs-lradc - add MODULE_ALIAS
 
 7) adc7606 - drop a work pending test duplicated in core functions.
 
 8) hmc5843 - devm_ allocation patch
 
 9) Series of redundant breaks removed.
 
 10) ad2s1200 - pr_err -> dev_err
 
 11) adjd_s311 - use INT_TIME
 
 12)  ST sensors - large set of cleanups from Lee Jones and removed restriction
     to using only triggers provided by the st_sensors themselves from
     Dennis Ciocca.
 
 13) dummy and tmp006 provide sampling_frequency via info_mask_shared_by_all.
 
 14) tcs3472 - fix incorrect buffer size and wrong device pointer used in
     suspend / resume functions.
 
 15) max1363 - use defaults for buffer setup ops as provided by the triggered
     buffer helpers as they are the same as were specified in max1363 driver.
 
 16) Trivial tidy ups in a number of other drivers.
