The driver currently supports only I2C access. But supported devices with an
accuracy of 8-bit are compatible with the SMBus byte access routines.

This patch wraps the send and receive routines depending on the chip
accuracy and fonctionnalities of its adapter.

For instance, this allows us to use a MAX11603 on a ICH7 controller.

use the struct max1363_state fields directly.

The macros `S626_CLKSRC_COUNTER`, `S626_CLKSRC_TIMER` and
`S626_CLKSRC_EXTENDER` are used logically to set the operating mode of
an encoder channel.  `S626_CLKSRC_COUNTER` (0) is also used as a 2-bit
physical value to set the counter source of an encoder channel to
"encoder".

Rename the macros to `S626_ENCMODE_COUNTER`, `S626_ENCMODE_TIMER` and
`S626_ENCMODE_EXTENDER` and rename some other macros and (unused)
functions relating to the encoder mode for consistency.

Define new macros to specify the physical counter source values for the
'CRA' register and rename the corresponding bitshift and mask macros
accordingly.  The physical values for the counter source are:

  S626_CNTSRC_ENCODER = 0      // encoder
  S626_CNTSRC_DIGIN = 1        // digital inputs
  S626_CNTSRC_SYSCLK = 2       // system clock up
  S626_CNTSRC_SYSCLK_DOWN = 3  // system clock down

Also use the `S626_CNTSRC_SYSCLK` value as a bitmask (bit 1) to indicate
either of the system clock values, with the direction (bit 0) indicated
separately in this case.

staging: comedi: s626: clock polarity and direction are the same

  S626_CLKPOL_POS = S626_CNTDIR_UP = 0

  S626_CLKPOL_NEG = S626_CNTDIR_DOWN = 1

In the construction of the setup value, both the CLKPOL and the CNTDIR
constants are shifted by the same amount `S626_BF_CLKPOL`.  Only the
following combinations are set up currently (this may change if user
configuration of the encoder is implemented properly):

  (S626_CLKPOL_POS << S626_BF_CLKPOL)

Use the shorter equivalents.  The comments in "s626.h" indicate that the

Jonathan writes:

Fourth round of IIO new drivers, functionality and cleanups for the 3.13 cycle.

New Drivers
* cm36651 combined RGB light and proximity sensor.

Core improvements

* Some more fixes and cleanups related to buffers.  These include the second
  half of a series which went is as fixes.  The basis for delaying until the
  next merge window is that some are too invasive for this late in a cycle
  and others only effect code paths current unused in the mainline tree.
  In this case we have:
   * protecting against concurrent userspace access
   * fixing a memory leak if a device goes away
   * avoiding always reallocating the buffer whether or not it has changed
     (a bug fix, but one with no functional changes other than a small speed
     improvement.)
   * Add reference counting for buffers to ensure they hang around if open
     from userspace or in kernel when the device is forcefully removed.
   * Return -ENODEV for buffer access operations when the device has gone
     away.
   * Add proper locking for iio_update_buffers (currently we only have one
     buffer per device in mainline, but an input bridge driver is under
     development which would make this bug 'real'.)
   * Wake up anyone waiting on a buffer if the device is unregistered.  A
     subsequent read will fail, notifying userspace that the device is no
     longer there rather than having it wait possibly for ever.

* Move the iio_sw_preenable functionality into the core.  This avoids drivers
  having to 'know' about how the buffers are implemented and is called by
  almost all drivers anyway.  Those that don't call it are not harmed by it
  being called.
* New registration approach for information (i.e. sysfs attributes) about
  events.  Much more generic and now similar to how the equivalent is
  handled for channel information.  The events infrastructure had been left
  behind by other changes so this brings it back in line.
* Using the new events registration approach, add a hysterisis event_info
  element and apply this to those drivers with this property.
* A little unitialized variable bug in the generic_buffer.c example.
* Factor out the code for freeing lists of IIO Device attributes to avoid
  some repitition.

Driver cleanups
* At91 driver gains touch screen support and some related fixes.
* Follow up series of patches removing the now redundant
  iio_sw_buffer_preenable calls.
* Lots of conversions to the new event registration methods.
* Another round of hmc5843 cleanups as that driver moves towards graduating
  from staging.
* Make some SoC drivers buildable if COMPILE_TEST is used.  Follow up fixes
  for a few bits and bobs that revealed.
* Add explicit includes of linux/of.h to those drivers making us of linux/of.h

iio: at91: introduce touch screen support in iio adc driver

AT91 ADC hardware integrate touch screen support. So this patch add touch
screen support for at91 adc iio driver.
To enable touch screen support in adc, you need to add the dt parameters:
  1. which type of touch are used? (4 or 5 wires), sample period time.
  2. correct pressure detect threshold value.

In the meantime, since touch screen will use a interal period trigger of adc,
so it is conflict to other hardware triggers. Driver will disable the hardware
trigger support if touch screen is enabled.

This driver has been tested in AT91SAM9X5-EK and SAMA5D3x-EK.
