Subject: [PATCH v4 0/9] iio: accel: bma400: Add buffer, step and activity/inactivity

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

changes since v3
1. Removed all the unnecessary mutex locking for regmap.
2. Corrected the mutex locking and unlocking for device private data
members.
3. Mutex locking and unlocking is used to protect the device private
structure members.
4. Using DMA safe buffer for regmap_bulk_write() and regmap_bulk_read().

1/9: Fixed the comment.

3/9: Added () for the function name in the comment.

4/9: Handling error cases with goto in bma400_trigger_handler().
Mutex locking and unlocking is used to protect the data->buffer.
Using DMA safe buffer for regmap_bulk_read().
Mutex locking and unlocking is used to protect the data->status in
bma400_interrupt.

5/9: Using DMA safe buffers to read steps value by allocating memory internally.
Using DMA safe buffers for regmap_bulk_write().
Removed the lock for regmap().

6/9: Removed the duplication of code for enabling step, added function to handle
the step enable.

7/9: Removed the lock for regmap().
Mutex locking and unlocking is used to protect the data members.

8/9: Removed the lock for regmap().

9/9. Added __be16 duration in struct bma400_data.
Fixed the warning - impossible condition '(reg < 0) => (0-255 < 0)'
Fixed error: call to __compiletime_assert_272
Reported-by: kernel test robot <[email protected]>
Reported-by: Dan Carpenter <[email protected]>

changes since v2
1. Reordering of header includes in the separate patch.
2. Matching the IIO syntax for multiline comment.
3. Following the preference in the interrupt handler for returning.
4. Add support for activity recognition.
5. Add support for debugfs to access registers from userspace.
6. Add support for activity and inactivity events

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().

iio: accel: bma400: Fix the scale min and max macro values

I have followed your comments from previous series and added the 'Fixes' tag for
patch 1, also added your 'Reviewed-by' tag for patch number 2 and 3 for which
you have given previously.

Hi Jagath,

This is coming together nicely. I'm fine with all the patches
I haven't sent specific replies for.

Thanks,

Jonathan
