This patch adds a DT and non-DT based implementation of the common clock infrastructure for Versatile Express platform. It registers (statically or using DT) all required fixed clocks, initialises motherboard's SP810 cell (that provides clocks for SP804 timers) and explicitly registers VE "osc" driver, to make the clock generators available early.

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.
