The MT6359 is a regulator found on boards based on MediaTek MT6779 and
probably other SoCs. It is a so called pmic and connects as a slave to
SoC using SPI, wrapped inside the pmic-wrapper.

This adds support for the MediaTek MT6359 PMIC. This is a
multifunction device with the following sub modules:

- Codec
- Interrupt
- Regulator
- RTC

It is interfaced to the host controller using SPI interface
by a proprietary hardware called PMIC wrapper or pwrap.
MT6359 MFD is a child device of the pwrap.

The Actions Semi ATC260x PMICs are able to manage an onkey button.
This driver exposes the ATC260x onkey as an input device. It can also
be configured to force a system reset on a long key-press with an
adjustable duration.

The currently supported chip variants are ATC2603C and ATC2609A.

Add initial support for the Actions Semi ATC260x PMICs which integrates
Audio Codec, Power management, Clock generation and GPIO controller
blocks.

For the moment this driver only supports Regulator, Poweroff and Onkey
functionalities for the ATC2603C and ATC2609A chip variants.

Since the PMICs can be accessed using both I2C and SPI buses, the
following driver structure has been adopted:

           -----> atc260x-core.c (Implements core functionalities)
          /
ATC260x --------> atc260x-i2c.c (Implements I2C interface)
