Add initial support for ROHM/Kionix kx022a accelerometer About the HW: KX022A accelerometer is a sensor which: - supports G-ranges of (+/-) 2, 4, 8, and 16G - can be connected to I2C or SPI - has internal HW FIFO buffer - supports various ODRs (output data rates) - support detecting special events like double tap or motion - can be configured to wake-up system when events are detected. About the series: This series adds support for only getting the accelerometer data and configuring the G-range / ODR via IIO. Motion detection or double-tap detection are not supported by the series. The other quite important but still missing piece is the runtime PM. Nevertheless, the driver should be usable and brings the basic support for getting accelerometer data. Changelog v4: (More detailed log in individual patches) - KX022A: mostly styling/print fixes. - KX022A: fix return value from IRQ thread handler. Changelog v3: (More detailed log in individual patches) - dt-bindings: fixed as suggested by Krzysztof - KX022A: multiple fixes as suggested by Andy - Fair to mention that couple of suggested changes are not done (Some styling, boilerplate text in KConfig) as there has been no consensus whether the suggested changes improve situation. Ultimately the decision whether these changes are mandatory lay on the shoulders of the maintainers... Sorry for that. - Enable the FIFO without module param now that the "FIFO stuck" issue can be prevented. - Fix potential race with time-stamp calculation when user-space invokes the fifo flush. - Drop the already merged regulator patches. Changelog v2: (More detailed log in individual patches) - dt-bindings: fixed as suggested by Krzysztof - dt-bindings: support both INT1 and INT2 - KX022A: multiple fixes as suggested by Jonathan - fixed SPI driver after some testing --- Matti Vaittinen (3): dt-bindings: iio: Add KX022A accelerometer iio: accel: Support Kionix/ROHM KX022A accelerometer MAINTAINERS: Add KX022A maintainer entry .../bindings/iio/accel/kionix,kx022a.yaml | 65 + MAINTAINERS | 5 + drivers/iio/accel/Kconfig | 21 + drivers/iio/accel/Makefile | 3 + drivers/iio/accel/kionix-kx022a-i2c.c | 51 + drivers/iio/accel/kionix-kx022a-spi.c | 58 + drivers/iio/accel/kionix-kx022a.c | 1145 +++++++++++++++++ drivers/iio/accel/kionix-kx022a.h | 82 ++ 8 files changed, 1430 insertions(+) create mode 100644 Documentation/devicetree/bindings/iio/accel/kionix,kx022a.yaml create mode 100644 drivers/iio/accel/kionix-kx022a-i2c.c create mode 100644 drivers/iio/accel/kionix-kx022a-spi.c create mode 100644 drivers/iio/accel/kionix-kx022a.c create mode 100644 drivers/iio/accel/kionix-kx022a.h base-commit: 9abf2313adc1ca1b6180c508c25f22f9395cc780 -- 2.37.3 -- Matti Vaittinen, Linux device drivers ROHM Semiconductors, Finland SWDC Kiviharjunlenkki 1E 90220 OULU FINLAND ~~~ "I don't think so," said Rene Descartes.
