iio: adc: New driver for the AB8500 GPADC

2019-10-18T18:37:44Z

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.

staging: iio: ad7780: moving ad7780 out of staging

2019-04-04T19:20:06Z

Move ad7780 ADC driver out of staging and into the mainline. The ad7780 is a sigma-delta analog to digital converter. This driver provides reading voltage values and status bits from both the ad778x and ad717x series. Its interface also allows writing on the FILTER and GAIN GPIO pins on the ad778x.

iio: adc: Add AD7768-1 ADC basic support

2019-02-02T10:28:56Z

The ad7768-1 is a single channel, precision 24-bit analog to digital converter (ADC). This basic patch configures the device in fast mode, with 32 kSPS and leaves the default sinc5 filter. Two data conversion modes are made available. When data is retrieved by using the read_raw attribute, one shot single conversion mode is set. The continuous conversion mode is enabled when the triggered buffer mechanism is used. To assure correct data retrieval, the driver waits for the interrupt triggered by the low to high transition of the DRDY pin.
