This driver allows to provide DT clocks for core clocks found on Marvell Kirkwood, Dove & 370/XP SoCs. The core clock frequencies and ratios are determined by decoding the Sample-At-Reset registers. Although technically correct, using a divider of 0 will lead to div_by_zero panic. Let's use a ratio of 0/1 instead to fail later with a zero clock.

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
|
