Message

This patch series adds trigger buffer support with data ready interrupt,
separate channel for step counter and an event for step change interrupt.

changes since v1
1. Added comment section that describes the math for scale calculation.
2. Added separate devm_add_action_or_reset() calls to disable regulator
   and to put the sensor in power down mode.
3. Remove the err_reg_disable and out, goto labels and returning directly
   if error occurs.
4. Added mutex calls while putting sensor in power down.
5. Added ___cacheline_aligned for device data.
6. Ordering the header includes.
7. Handling erroneous and spurious interrupts in the interrupt handler
   by returning IRQ_NONE.
8. Using dev_err_probe() instead of dev_err().
9. Configured the interrupt to open drain.
10. Using le16_to_cpu() to fix the sparse warning.
11. Checking the step change event is enabled or not.
12. Enabling the step change event will also enable the step channel.
13. Using FIELD_GET() instead of bitwise operation.
14. Removal of dead code in the _event_config().
