KX022A is a 3-axis accelerometer from ROHM/Kionix. The sensor features include variable ODRs, I2C and SPI control, FIFO/LIFO with watermark IRQ, tap/motion detection, wake-up & back-to-sleep events, four acceleration ranges (2, 4, 8 and 16g), and probably some other cool features. Add support for the basic accelerometer features such as getting the acceleration data via IIO. (raw reads, triggered buffer [data-ready] or using the WMI IRQ). Important things to be added include the double-tap, motion detection and wake-up as well as the runtime power management.

Hi, should there be a v5:
+/* + * The KX022A has FIFO which can store 43 samples of HiRes data from 2
Nit: 2 here, but 3 the lines just before.
+ * channels. This equals to 43 (samples) * 3 (channels) * 2 (bytes/sample) to + * 258 bytes of sample data. The quirk to know is that the amount of bytes in + * the FIFO is advertised via 8 bit register (max value 255).
