Hello,
This patchset adds support for sensorhub. It is an external mcu which
manages and collects data from several sensors i.e. on Galaxy Gear 2 watch.
It contains:
- spi driver for sensorhub device
- DT binding for the device
- IIO common utils for ssp sensors (iio kfifo setup helpers, pre/post callbacks)
- IIO accelerometer driver
- IIO gyroscope driver
For now the driver supports "traditional" sensors but new ones types are
intended to be used.
The patchset depends on INDIO_BUFFER_SOFTWARE adding patch.
>From v1:
- Adopted to new stm32fwu v5
- Fixed sensors' data process callbacks
- Fixed comments style
>From v2:
- Fixes after Hartmut Knaack review
- Sensorhub driver was moved from misc to iio after the discussion with Arnd
and Jonathan
- Firmware upgrade is not supported in this patchset. I hope it will be
applied when it will find its own place in the tree.
>From v3:
- change buffer allocation manner for iio devices buffers
- centralize irq buffer
- style fixes
- sensors' devices as mfd cells
- remove iio_buffer_register from the sensorhub drivers
- fix DT binding and remove optional attributes
>From v4:
- fix Kconfig - missing MFD_CORE dependency
- rebase on next-20150128
- remove THIS_MODULE usage in sensors' drivers as not needed
Thanks,
Karol
