2019-10-22iio: adc: hx711: optimize performance in read cycleAndreas Klinger
Set gain in hx711_reset() to its default value after a reset cycle. This omits one precautionary read cycle, because the read is performed in hx711_set_gain_for_channel() anyway if gain has changed. Check for DOUT low and if its high wait some time if it goes down instead of doing a blind reset cycle when DOUT is not down. This is a performance optimization which allows to query the sensor with a higher frequency.

2019-10-22iio: pressure: zpa2326: fix iio_triggered_buffer_postenable positionAlexandru Ardelean
The iio_triggered_buffer_{predisable,postenable} functions attach/detach the poll functions. The iio_triggered_buffer_postenable() should be called before (to attach the poll func) and then the The iio_triggered_buffer_predisable() function is hooked directly without anything, which is probably fine, as the postenable() version seems to also do some reset/wake-up of the device. This will mean it will be easier when removing it; i.e. it just gets removed.

2019-10-18mfd: Switch the AB8500 GPADC to IIOLinus Walleij
The AB8500 GPADC driver is indeed a "general purpose ADC" driver, and while the IIO subsystem did not exist when the driver was first merged, it is never too late to clean things up and move it to the right place. Nowadays IIO provides the right abstractions and interfaces to do generic ADC work in the kernel. We have to cut a bunch of debugfs luggage to make this transition swift, but all these files to is read out the raw values of the ADC and the IIO subsystem already has a standard sysfs ABI for doing exactly this: no debugfs is needed.

2019-10-18iio: adc: New driver for the AB8500 GPADCLinus Walleij
This is a new driver for the ST-Ericsson AB8500 GPADC, which replaces the old driver in drivers/mfd/ab8500-gpadc.c and thus gets rid of another necessarily different custom driver from the times before IIO existed. The AB8500 GPADC can convert 10 different channels and these are used for monitoring voltages in the U8500 chipset, some are used for battery charging, some for temperature monitoring. As this is very core functionality that a lot of drivers depend on and was formerly compiled in with the AB8500 core driver, we deafault it to 'y' in Kconfig: it can be compiled out but it is really not advisible: the platform can for example overheat if we do.
