Add initial support for ROHM/Kionix kx022a accelerometer This series is not ready for being merged as such. The first two patches in the series (the new regulator devm interfaces) are already merged to Mark's tree but have not yet found their way to the mainline. This is the reason I marked series as RFC. You can also skip the reviewing of first two patches as they are there just to make the series compile on top of the v6.0-rc7. I will re-spin the series without the patches 0001 and 0002 and drop the RFC tag when the v6.1-rc1 is out. 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.
