Subject: [PATCH v5 0/5] iio: Add sensorhub driver
Date: Wed, 28 Jan 2015 15:05:49 +0100	[thread overview]
Message-ID: <1422453954-27317-1-git-send-email-k.wrona@samsung.com> (raw)

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
