From 07063bbfa98e60916bf4805e490736d96d137e9d Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Fri, 11 Oct 2019 09:18:04 +0200 Subject: iio: adc: New driver for the AB8500 GPADC 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.
