Jonghwa Lee 73118e6188 clock: max77686: Add driver for Maxim 77686 32Khz crystal oscillator.
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.

---help---
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
this option.

Creates a directory hierchy in debugfs for visualizing the clk

that export information specific to that clk node: clk_rate,
clk_flags, clk_prepare_count, clk_enable_count &
clk_notifier_count.
