The initial implementation of the driver adds read support for the acceleration and temperature data registers. The driver also has support for reading and writing to the output data rate, oversampling ratio, and scale configuration registers. Version 3 implements the feedback from reviewers of the v2 patchset. Cheers, - Dan Changes in v3: * Use yaml format for DT bindings * Remove strict dependency on OF * Tidy Kconfig dependencies * Stylistic changes * Do not soft-reset device on remove Changes in v2: * Implemented iio_info -> read_avail * Stylistic changes * Implemented devicetree bindings Dan Robertson (2): dt-bindings: iio: accel: bma400: add bindings iio: (bma400) add driver for the BMA400 .../devicetree/bindings/iio/accel/bma400.yaml | 39 + drivers/iio/accel/Kconfig | 18 + drivers/iio/accel/Makefile | 2 + drivers/iio/accel/bma400.h | 80 ++ drivers/iio/accel/bma400_core.c | 788 ++++++++++++++++++ drivers/iio/accel/bma400_i2c.c | 60 ++ 6 files changed, 987 insertions(+) create mode 100644 Documentation/devicetree/bindings/iio/accel/bma400.yaml create mode 100644 drivers/iio/accel/bma400.h create mode 100644 drivers/iio/accel/bma400_core.c create mode 100644 drivers/iio/accel/bma400_i2c.c
