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.
