Jonathan writes: First set of IIO fixes for the 4.13 cycle. * ad2s1210 - Fix negative angular velocity reads (identified by a gcc 7 warning) * aspeed-adc - Wait for initialization sequence to finish before enabling channels. Without it no channels work. * axp288 - Revert a patch that dropped some bogus register mods. No one is entirely sure why but it breaks charging on some devices. - Fix GPADC pin read returning 0. Turns out a small sleep is needed. * bmc150 - Make sure device is restored to normal state after suspend / resume cycle. Otherwise, simple sysfs reads are broken. * tsl2563 - fix wrong event code. * st-accel - add spi 3-wire support. Needed to fix the lsm303agr accelerometer which only had 3 wires in all cases. Side effect is to enable optional 3-wire support for other devices. * st-pressure - disable multiread by default for LPS22HB (only effects SPI) * sun4i-gpadc-iio - fix unbalanced irq enable / disable * vf610 - Fix VALT slection for REFSEL bits - ensures we are using the right reference pins.

iio: light: tsl2563: use correct event code

2017-06-24T19:42:49Z

The TSL2563 driver provides three iio channels, two of which are raw ADC channels (channel 0 and channel 1) in the device and the remaining one is calculated by the two. The ADC channel 0 only supports programmable interrupt with threshold settings and this driver supports the event but the generated event code does not contain the corresponding iio channel type. This is going to change userspace ABI. Hopefully fixing this to be what it should always have been won't break any userspace code.

We want the IIO fixes and other staging driver fixes in here as well. Signed-off-by: Greg Kroah-Hartman

iio: light: rpr0521 channel numbers reordered

2017-05-21T14:06:15Z

Move proximity channel from last to first in structs to avoid confusion later with buffered triggers. Proximity data output is first in rpr0521 register map. Signed-off-by: Mikko Koivunen Acked-by: Daniel Baluta Signed-off-by: Jonathan Cameron

iio: light: rpr0521 proximity offset read/write

2017-05-21T14:06:15Z

Add sysfs read/write proximity offset feature. Offset is read/write from sensor registers. Values are proximity raw 10-bit values. After applying offset value, output values will be (measured_raw - offset_value). Output values are unsigned so offset value doesn't make output negative.

iio: light: rpr0521 on-off sequence change for CONFIG_PM

2017-05-21T14:06:12Z

Refactor _set_power_state(), _resume() and _suspend(). Enable measurement only when needed, not in _init(). System can suspend during measurement and measurement is continued on resume. Pm turns off measurement when both ps and als measurements are disabled for 2 seconds. During off-time the power save is 20-500mA, typically 180mA.

iio: light: rpr0521 poweroff for probe fails

2017-05-21T14:06:11Z

Set sensor measurement off after probe fail in pm_runtime_set_active() or iio_device_register(). Without this change sensor measurement stays on even though probe fails on these calls. This is maybe rare case, but causes constant power drain without any benefits when it happens. Power drain is 20-500uA, typically 180uA.
