Hi,
This series introduce a NXP fxas21002c tri axis gyroscope driver [0]
It add a core implementaiton plus an i2c and spi.
This device can be found in the warp7 board [1], where it was tested.

Cheers,
Rui
v3->v4:
Tomasz Duszynski:
- mention irq flags in bindings
- add reference to drive-open-drain in bindings
- fix headers files
- drop comas in of_device_id sentinel
- drop of_match_ptr
- use probe_new
Joan Cameron:
- disable vdd regulator in case of vddio fail
- use devm_add_action_or_reset
- simpler functions returns
- remove noisy dev_info
- remove EAGAIN from runtime_suspend
v2->v3:
Jonathan Cameron:
- cacheline aligned (DMA safe buffer)
Great presentation [2] and links in the presentation, thanks
- global renaming, including filenames, fxas2100x->fxas21002c
- provide spi info in dts bidings
- Remove SPI_MASTER in Kconfig i2c patch and move it to right patch
- remove extra blank line in comment
- add break range_value_from_fs after found
- in range_value_from_fs use local variable
- remove mode check at mode_set
- combine two if statements in mode_set
- in scale_get return 0 and let caller to set IIO_VAL_FRACTIONAL
- remove dev_err from vdd_io regulator get
- handle regulator error path
- devm_add_action
- check unwind order
- simplify data in _suspend and alike
- disable regulators at suspend
- error handling at _resume
- return -EAGAIN at runtime_resume
Rob Herring:
- Set label as gyroscope
- add interrupt to bindings
- add entry to maintainers
v1->v2:
Peter Meerwal-Stadler:
- changed (c) to current year
- add regmap include file in .h
- fix comments s/cuttof/cutoff/
- add more info in mutex comment
- check value in range_fs_from_value
- ret not checked in range_value_from_fs
- move mode to enum type
- remove line between value get and validation of value in all file
- pre-write, regmap_field_write, post_write refactoring
- check val2 and val == 0 in write raw
- check in_anglvel_scale: 7.8125?
- trigger_handler: 2 => sizeof(s16)
- check buffer size
- print %02% to output chip id
- remove !! as state is bool
- trigger probe return devm_iio_trigger_register
- remove error msg in case of devm_iio_device_register
Fabio Estebam:
- rename FXAS2100X to FXAS21002
- change compatible nxp,fxas2100x to the exact support
- add VDD and VDDIO regulators in bindings and driver
