[PATCH v3 0/2] iio:gyro:bmg160 Gyro Sensor driver

[Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com>]

v3
- Suport Only Runtime PM no fallback method. Driver will still work but
chip will be in power on mode.
- Add comment for enable disable trigger/event sequence, how they work
in reverse order using runtime pm calls

v2:
- Add device id in any-motion trigger
- Removed string comparison for trigger name to identify trigger source
- Prevent disabling any motion interrupts when both any motion trigger
and events are on, but any one of them is disabled via sysfs
- Switch on chan->type
- Created new function to raw read axis
- Explanation why need to power on for changing sampling freq and scale

v1:
- Runtime PM: Removed module parameter for delay configuration
Use RTPM autosuspend delay feature. This allows sysfs configuration of
autosuspend time.

- Trigger
As suggested, there are two triggers:
- data_ready : Trigger which will allow all gyro periodic sampled data to
be received by user space
- any-motion: When used, will configure the chipset so that data is
pushed only when there is any motion, allowing system to enter deeper idle
power states

- Events
ROC type events will send direction instead of either.
Also both events and data triggers can be enabled together.

- Addition of unbuffered TEMP read interface

- Misc error message corrections as suggested by Peter Meerwald

TBD: Add sysfs attribute to trigger to configure thresholds.
Currently the triggers don't have feature to add sysfs attributes
unlike IIO device. But this has to be a RFC patch on top. 

v0:
Base version for review
