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 Karol Wrona (5): iio: common: ssp_sensors: Add sensorhub driver iio: sensorhub: Add sensorhub bindings iio: common: ssp_sensors: Add sensorhub iio commons iio: common: ssp_sensors: Add sensorhub accelerometer sensor iio: common: ssp_sensors: Add sensorhub gyroscope sensor .../devicetree/bindings/iio/sensorhub.txt | 25 + drivers/iio/accel/Makefile | 1 + drivers/iio/accel/ssp_accel_sensor.c | 169 +++++ drivers/iio/common/Kconfig | 1 + drivers/iio/common/Makefile | 1 + drivers/iio/common/ssp_sensors/Kconfig | 26 + drivers/iio/common/ssp_sensors/Makefile | 8 + drivers/iio/common/ssp_sensors/ssp.h | 257 +++++++ drivers/iio/common/ssp_sensors/ssp_dev.c | 712 ++++++++++++++++++++ drivers/iio/common/ssp_sensors/ssp_iio.c | 107 +++ drivers/iio/common/ssp_sensors/ssp_iio_sensor.h | 70 ++ drivers/iio/common/ssp_sensors/ssp_spi.c | 608 +++++++++++++++++ drivers/iio/gyro/Makefile | 2 + drivers/iio/gyro/ssp_gyro_sensor.c | 168 +++++ include/linux/iio/common/ssp_sensors.h | 82 +++ 15 files changed, 2237 insertions(+) create mode 100644 Documentation/devicetree/bindings/iio/sensorhub.txt create mode 100644 drivers/iio/accel/ssp_accel_sensor.c create mode 100644 drivers/iio/common/ssp_sensors/Kconfig create mode 100644 drivers/iio/common/ssp_sensors/Makefile create mode 100644 drivers/iio/common/ssp_sensors/ssp.h create mode 100644 drivers/iio/common/ssp_sensors/ssp_dev.c create mode 100644 drivers/iio/common/ssp_sensors/ssp_iio.c create mode 100644 drivers/iio/common/ssp_sensors/ssp_iio_sensor.h create mode 100644 drivers/iio/common/ssp_sensors/ssp_spi.c create mode 100644 drivers/iio/gyro/ssp_gyro_sensor.c create mode 100644 include/linux/iio/common/ssp_sensors.h -- 1.7.9.5 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
