The Qualcomm SPMI PMIC chips are components used with the Snapdragon 800 series SoC family. This driver exists largely as a glue mfd component, it exists to be an owner of an SPMI regmap for children devices described in device tree.

This adds driver to support HiSilicon Hi6421 PMIC. Hi6421 includes multi- functions, such as regulators, codec, ADCs, Coulomb counter, etc. This driver includes core APIs _only_. Drivers for individul components, like voltage regulators, are implemented in corresponding driver directories and files. Registers in Hi6421 are memory mapped, so using regmap-mmio API.

Ricoh RN5T618 is a power management IC which integrates 3 step-down DCDC converters, 7 low-dropout regulators, a Li-ion battery charger, fuel gauge, ADC, GPIOs and a watchdog timer. This commit adds a MFD core driver to support the I2C communication with the device. Signed-off-by: Beniamino Galvani <b.galvani@gmail.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
The interfaces that used to be built in only (interrupts IIRC) no longer are so allow the driver to be built as a module fixing arm64 allmodconfig builds.

The MEN 14F021P00 Board Management Controller provides an I2C interface to the host to access the feature implemented in the BMC. The BMC is a PIC Microntroller assembled on CPCI Card from MEN Mikroelektronik and on a few Box/Display Computer. Added MFD Core driver, supporting the I2C communication to the device. The MFD driver currently supports the following features: - Watchdog - LEDs - Hwmon (voltage monitoring) Signed-off-by: Andreas Werner <andreas.werner@men.de> Signed-off-by: Lee Jones <lee.jones@linaro.org>
Maxim MAX77802 is a power management chip that contains 10 high efficiency Buck regulators, 32 Low-dropout (LDO) regulators used to power up application processors and peripherals, a 2-channel 32kHz clock outputs, a Real-Time-Clock (RTC) and a I2C interface to program the individual regulators, clocks outputs and the RTC. This patch adds support for MAX77802 to the MAX77686 driver and is based on a driver added to the Chrome OS kernel 3.8 by Simon Glass.
