This is a small, mainly to get a couple of compile bug related fixes into
the tree ASAP.
New device support:
1) Add ad5446 dac support to the ad5641 driver.
New functionality and cleanups:
1) Optional power supply regulators for the st pressure sensors drivers using
the new optional regulator interface.
2) Bit of tidying up of naming in the sysfs trigger.
Bug fixes from the previous series:
1) Missing select IIO_BUFFER for ti_am335x_adc
2) Drop a bonus bracket in iio-trig-bfin-timmer

Second set of new functionality for IIO in the 3.13 cycle - with bug fixes for first set.

This patch fixes the following compile errors for the iio-trig-bfin-timer
driver:
drivers/staging/iio/trigger/iio-trig-bfin-timer.c: In function ‘iio_bfin_tmr_frequency_store’:
drivers/staging/iio/trigger/iio-trig-bfin-timer.c:121: error: invalid storage class for function ‘iio_bfin_tmr_frequency_show’

strict_strto*() with kstrto*()") by leaving an excess opening bracket.

The lux_uscale value is not initialized at probe. The value will be
uninitialized unless a value is written to it through the iio channel interface.
This fixes that.

This only occurs in the unlikely event that the example driver is built
in whilst the buffer implementation is not.
Solved by switching from a depends on to a select for this particular case.

The usage of strict_strto*() is not preferred, because
strict_strto*() is obsolete. Thus, kstrto*() should be
used.
Previously, there were only strict_strtol(), strict_strtoul(),
strict_strtoull(), and strict_strtoll(). Thus, when converting
to the variables, only long, unsigned long, unsigned long long,
and long long can be used.
However, kstrto*() provides various functions handling all types
of variables. Therefore, the types of variables can be changed
properly.
