Sorted header files and added unit.h - Splitting macro - Defined new macros and enums to use in place of magic numbers. - Used KILO instead of large number - Used guard and scoped_guard from cleanup.h - Used ARRAY_SIZE() instead of value - Replaced kstrtoint with kstrtobool - Used min() and in_range() from minmax.h - Used GENMASK instead of magic number - Remove error print from interrupt handler - Removed casting and le16_to_cpup, used sign_extend32 for getting final value - Used while loop instead of for - Remove the check for the return value of 0 from fwnode_irq_get_byname() - Used dev_err_probe() in all probe paths - Removed 0 from i2c_ids[] - Used read_flag_mask for spi regmap configuration - Dropped blank line - Used regmap_read_poll_timeout() function instead of while loop - Applied fixes as per review Review by Jonathan - Used oversampling instead of averaging - Reverse the order of avail_scan_masks - Use FIELD_PREP() directly in place of set_mask_bits - Remove irq_type from devm_request_threaded_irq - Use FIELD_GET() with mask - Added comment for delay used for feature engine enable - Use dev_err_probe in all probe paths - For I2C regmap, allocated memory in device private data - Use pad_bits=16 for spi regmap_configuration - Added both interrupts in the dt-bindings Review by Krzysztof Kozlowski - Removed duplicated words from subject - Removed '|' - Added supplies - Used generic node name "imu" - Removed spi example node Review by Uwe Kleine-König - Use probe instead of probe_new - Placed datasheet in driver Jagath Jog J (2): dt-bindings: iio: imu: Add Bosch BMI323 iio: imu: Add driver for BMI323 IMU Documentation/ABI/testing/sysfs-bus-iio | 18 + .../bindings/iio/imu/bosch,bmi323.yaml | 77 + MAINTAINERS | 7 + drivers/iio/imu/Kconfig | 1 + drivers/iio/imu/Makefile | 1 + drivers/iio/imu/bmi323/Kconfig | 33 + drivers/iio/imu/bmi323/Makefile | 7 + drivers/iio/imu/bmi323/bmi323.h | 209 ++ drivers/iio/imu/bmi323/bmi323_core.c | 2139 +++++++++++++++++ drivers/iio/imu/bmi323/bmi323_i2c.c | 121 + drivers/iio/imu/bmi323/bmi323_spi.c | 92 + 11 files changed, 2705 insertions(+) create mode 100644 Documentation/devicetree/bindings/iio/imu/bosch,bmi323.yaml create mode 100644 drivers/iio/imu/bmi323/Kconfig create mode 100644 drivers/iio/imu/bmi323/Makefile create mode 100644 drivers/iio/imu/bmi323/bmi323.h create mode 100644 drivers/iio/imu/bmi323/bmi323_core.c create mode 100644 drivers/iio/imu/bmi323/bmi323_i2c.c create mode 100644 drivers/iio/imu/bmi323/bmi323_spi.c -- 2.20.1
