This patch supports max77686 mfd's clock driver using common clock frame work. max77686 has 3 clock ouputs which all are generated from crystal oscillator and SOC can enable/disable them via I2C bus. All clocks are fixed-rate clock sources so that it doesn't supply interface for changing clock rate. Driver uses regmap API to communicate with internal register.

The common clock framework is a single definition of struct
|

clk, useful across many platforms, as well as an
|
|
implementation of the clock API in include/linux/clk.h.
|

Architectures utilizing the common struct clk should select
