Hi,

The <linux/clk.h> provides the API to use clocks.
However there is no API for clock providers. Commonly
clocks are provided by platform-specific code, which
implements full <linux/clk.h> API for itself. It results
in massive code duplication and lack of flexibility.
If I'd like to be able to provide clocks from the driver
for e.g. CPU companion chip, I'd either have to implement
a lot of platform-specific hooks, or invent some other
dirty hacks.

In the followup I'd like to propose the generic <linux/clk.h>
implementation, that can be used to hook clock definitions
from various sources. Also as an example there will be a patch
to convert ARM SA-1100 to the clocklib.

I'd like arch maintainers to check whether there is somthing
in this implementation that wouldn't work for their piece
of kernel, whether is's suitable for them to drop their own
clock implementation (if any) and to use clocklib.
