This series implements a set of drivers allowing to support the Maxim
Integrated MAX7360 device.
The MAX7360 is an I2C key-switch and led controller, with following
functionalities:
- Keypad controller for a key matrix of up to 8 rows and 8 columns.
- Rotary encoder support, for a single rotary encoder.
- Up to 8 PWM outputs.
- Up to 8 GPIOs with support for interrupts and 6 GPOs.
Chipset pins are shared between all functionalities, so all cannot be
used at the same time.
Lee Jones suggested the whole series goes through MFD subsystem, once
all patches got the needed Acks.

Hi Lee, The PWM driver just got Acked, so I believe we are good to go. Please tell me if there is anything else I need to do.
