Many platforms support simple gateable clocks, fixed-rate clocks,
adjustable divider clocks and multi-parent multiplexer clocks.
This patch introduces basic clock types for the above-mentioned hardware
which share some common characteristics.
Based on original work by Jeremy Kerr and contribution
The common clock framework defines a common struct clk useful across
most platforms as well as an implementation of the clk api that drivers
can use safely for managing clocks.
The net result is consolidation of many different struct clk definitions
and platform-specific clock framework implementa
Provide documentation for the common clk structures and APIs. This code
can be found in drivers/clk/ and include/linux/clk*.h.

The common clock framework defines a common struct clk as well as an
implementation of the clk api that unifies clock operations on various
platforms and devices.
The net result is consolidation of many different struct clk definitions
and platform-specific clock framework implementations.

Anatop is an integrated regulator inside i.MX6 SoC.
There are 3 digital regulators which controls PU, CORE (ARM), and SOC.
And 3 analog regulators which controls 1P1, 2P5, 3P0 (USB).
This patch adds the Anatop regulator driver.

Use DIV_ROUND_UP to avoid the possible truncate of integer division.
This ensures the selected volatge falls within the specified range
