iio: accel: bmc150: use common definition for regmap conf (2016-04-03 11:24:52 +0100)

----------------------------------------------------------------
First round of IIO new device support, features and cleanups for the 4.7 cycle.

New core support
* UV light modifier (for intensity)
* UV light index channel type.

New device support
* hp206c barometer and altimeter
- new driver.
* mcp4131 potentiometer
- new driver supporting lots of parts from Microchip.
* mma8452
- FXLS8471Q support
- NXP LPC18XX SOC ADC
- new driver.
- NXP LPC18XX SOC DAC
- new driver.
- rockchip_saradc
- support rk3399
* st accel
- h3lis331dl support

Staging driver removals
* adis16204
- obsolete part making it hard to get parts to test the driver in order to clean it up.
* adis16220
- obsolete part making it hard to get the parts test the driver in order to clean it up.

Features
* core
- convenience functions to claim / release direct access to the device. Makes more consistent handling of this corner easier. Used in ad7192 driver.
* ak8975
- power regulator support.
* at91-sama5d2
- differential channel support.
* mma8452
- runtime pm support
- drop device specific autosleep and use the runtime pm one instead.
* ms5611
- DT bindings
- oversampling ratio support

Cleanups and minor fixes
* MAINTAINERS
- Peter got married - hence name change!

* Documentation
- Fix a typo in in_proximity_raw description.
- Add some missing docs for iio_buffer_access_funcs.

* Tools
- update iio_event_monitor names to match new stuff.
- make generic_buffer look for triggers ending in -trigger as we let these in for a number of drivers a long time back and now it is a fairly common option.

Drivers
* staging wide
- convert bare unsigned usage to unsigned int to comply with coding style.
* non staging wide:
- since boiler plate gpio handling of interrupts has been moved into the ACPI core we don't need to include gpio/consumer.h in a load of drivers so drop it.
* ad7606
- fix an endian casting sparse warning.
* ak8975
- fix a possible unitialized warning from gcc.
- drop and unused field left over from earlier cleanups
- fix a missing regulator_disable on exit.
* at91-sama5d2
- typo and indentation
- missing IOMEM dependency.
- cleanup mode register usage by avoidling erasing whole thing when changing the sampling frequency.
* bmc150
- use the core demux and available_scan_masks to simplify buffer handling
- optimize the transfers in the trigger handler now we have a magic function to emulate bulk reads (under circumstances met here). This matters with some rather dumb i2c adapters in particular.
- use a single regmap_conf for all bus types as they were all the same.
* bmg160
- use the core demux and available_scan_masks to simplify the buffer handling
- optimize the transfers in the trigger handler now we have a magic funciton to emulate bulk rads (under circumstances met here).
- drop gpio interrupt probing from the driver (ACPI) as now handled by the ACPI core.
* ina2xx-adc
- update the CALIB register when RShunt changes.
- fix scale for VShunt - in reality this error canceled out when used.
* isl29028
- use regmap to retrieve the struct device instead of carrying a second copy of it around.
* kxcjk-1013
- use core demux
- optimize i2c transfers in the trigger handler.
* mcp4531
- refactor to use a pointer to access model parameters instead of indexing into the array each time.
* mma8452
- style fixes
- avoid swtiching to active whenever the config changes
- add missin i2c_device_id for mma8451
* mpu6050
- fix possible NULL dereference.
- fix the name / chip_id used when ACPI used (otherwise reports as NULL).
* ms5611
- fix a missing regulator_disable that left the regulator on during removal.
* mxc4005
- drop gpio interrupt handling for ACPI case from driver as the core now handles this case.
* st-sensors
- note that there are only ever a maximum of 3 axis on current st-sensors so just allocate a fixed sized buffer big enough for that.
* tpl0102
- change the i2c_check_functionality condition to bring it inline with other IIO users as EOPNOTSUPP.
* tsl2563
- replace deprecated flush_scheduled_work

Hi Greg,

Note there is a merge conflict with one of the patches in the second lot of fixes I sent early today. This is because the change got queued up here first then we noticed and issue which it fixed by accident.

Anyhow, conflict is in bmg160-core.c and you want the 'short option'. For comparison, the code is pretty much identical to bmc150-accel-core.c.

Otherwise, various automerged corners that seem to be fine. My build tests failed on a random thermal driver which I'll assume has long since been fixed, but otherwise seemed fine.

I've done the merge now, can you verify I got it correct?
