Uwe Kleine-König	7cf15f4275	iio: Switch i2c drivers back to use .probe() ... After commit b8a1a4cd5a ("i2c: Provide a temporary .probe_new() call-back type"), all drivers being converted to .probe_new() and then 03c835f498 ("i2c: Switch .probe() to not take an id parameter") convert back to (the new) .probe() to be able to eventually drop .probe_new() from struct i2c_driver.

Matti Vaittinen	a508fbfed3	iio: kx022a: Probe asynchronously ... Devices which may take a while to initialize during probe and which have no strong reason to probe synchronously can request asynchronous probing as default probe strategy. This can speed-up start times on some platforms. The KX022A gets probe delayed for at least two reasons. It enables the supply regulator, (which is likely to have ramp-up delay if it was disabled) and additionally it delays while the sensor itself is initializing. Changing to asynchronous probing may cause problems. Some of which are discussed in: https://lore.kernel.org/all/06db017f-e985-4434-8d1d-02ca2100cca0@sirena.org.uk/ Enable asynchronous probing for KX022A.

Matti Vaittinen	7c1d1677b3	iio: accel: Support Kionix/ROHM KX022A accelerometer ... 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.
