switch from using REGCACHE_FLAT to REGCACHE_RBTREE so initial hw values
are read from device. This also allows some volatile ranges to be
dropped.
Note that REGCACHE_FLAT is intended only for very low lag cases so doesn't
do nice things like read initial values from the device. Hence this change.

The newly added afe4403 driver uses the regmap facility to abstract

is actually present:
drivers/iio/built-in.o: In function `afe4403_probe':

2nd round of new IIO device support, features and cleanups for the 4.6 cycle.
New Device Support
* Apex stx104 DAC
- new driver for this PC104 board. Right now DAC support only.
* ADI ad5064
- Add support for ad5625, ad5627, ad5645, ad5665, ad5667 DACs.
- Add support for Linear Technology ltc2606, ltc2607, ltc2609, ltc2616,
ltc2617, ltc2619, ltc2626, ltc2627 and ltc2629.
* ADI ad7192
- add support for the ad7193
* Invensense mpu6050
- substantial rework of driver to use regmap allowing SPI support extending
the now split driver to cover the MPU6000.
* TI adc0832
- new driver supporting ADC0831, ADC0832, ADC0834 and ADC0838 ADCs.
* TI ads1015
- new driver, note that there is an existing hwmon driver. The long term
intention is to probably remove the hwmon driver but for now we just have
guards in place to ensure this driver is not built if that one is enabled.
* TI afe4403
- new driver for this heart rate monitor / pulse oximeter front end chip.
* TI afe4404
- new driver for this heart rate monitor / pulse oximeter front end chip.
Staging Graduations
* mxs-lradc
- A combined general purpose and touch screen (input) device driver.
Originally held in staging to allow reworking into and MFD but as
that wasn't happening and isn't an absolute requirement we are moving
it out of staging.
Driver new features
* ms5611
- triggered buffer support
- IIO_CHAN_INFO_SCALE to aid the triggered buffer support.
Driver cleanups / reworks / fixes
* ad5064
- Use an enum for the register map layout to allow support of additional
chips (precursor to the new support listed above).
- Structural driver changes to allow support of the slightly different
handling for the ltc parts above.
* ad5933
- drop an exceptional & unnecessary for a function pointer.
* ad7606
- Cleanup the repeated copies of pm ops.
- consolidate the various channels specs via a sport of rearranging so only
one version is needed.
* atlas ph sensor
- add select IRQ_WORK
* hmc8543 (soon to move out of staging)
- Comment style fixes
- functionality of suspend and resume was swapped.
* spear-adc
- use devm_clk_dev instead of managing the clk lifetime by hand.
Core
* Use new dmaengine_terminate_sync call to avoid a theoretical race.
* Fix docs for mlock in struct iio_dev as it is correctly taken in some
drivers (docs used to say for core only).
* Add a helper function for calculating the scan index storage size within
the core cutting out some cut and paste versions of the same code.

2-channel 16-bit analog output PC/104 card. The STX104 incorporates a

The AD5625/AD5645/AD5665 are a family of 4 channel DACs with 12-bit, 14-bit
and 16-bit precision respectively. The devices come in 3 flavors in terms
of built-in reference, either no built-in reference, built-in 1.25V
reference or built-in 2.5V reference.
The AD5627/AD5647/AD5667 are similar to the AD5625/AD5645/AD5665 except
that they have 2 instead of 4 channels.
While these new devices are mostly register map compatible with the
existing devices support by the driver some offsets and register addresses
have been shuffled around. To accommodate this introduce a new register map
layout. For the lack of a better name we will just call it version 2.

This patch makes minor structural changes to support specifics
for LTC2617 DAC. This DAC requires different handling of the
power down modes. The configuration to actually support the
DAC will be submitted in a secondary patch.
Adjust the DECLARE_AD5064_CHANNELS() macro to accept a new
ext_info parameter. This allows to use different power down
modes per DAC. (e.g. DAC only support 90kohm to ground)
Add the chip_info parameter "powerdown_ltc". This parameter is
used in the ad5064_sync_powerdown_mode() function to handle the
power down command for LTC diffently. For those devices the
power down command must be addressed to the channel.

use of the IIO ABI. However, old _raw version retained to avoid
breaking any userspace in the wild that is relying on that (none
known but it doesn't hurt us much to retain it)
* ade7753
- fix some error handling to avoid use of unitialized data.
* ltr501
- use a signed return type for ltr501_match_samp_freq so as to allow
returning of an error code.
* mcp4725
- set name field of struct iio_dev to ensure the sysfs name attribute
doesn't give NULL.
* mpl115
- temperature offset sign is wrong.
* stk8ba50
- IIO_TRIGGER dependency added
* ti_am335x_adc
- Label buffer as a software buffer. It's actually a hybrid of a
true hardware buffer feeding a kfifo, but the meaning of these fields
has changed a little recently and in this case it should be labeled
a software buffer ensure it is allowed to use the kfifo.

Instead of guessing where the data starts, we now just try to decode from
every possible start position. This causes no additional overhead if we
properly received the full preamble and only costs a few extra CPU cycles
in the case where the preamble is corrupted. This is much more efficient
than to return an error to userspace and start over again.

mpl115 driver currently supports i2c interface (MPL115A2).
There is also SPI version (MPL115A1). The difference between them
is only physical transport so we can easily support both while sharing
most of the code.
Split the driver into a core support module and one module each for I2C
and SPI support.
