There are some parts of common kernel which would be using routines like clk_get_rate() on some platforms. Currently these wouldn't be called for SA1100 boards but we need these routines for successful builds of these boards.
So, this patch creates a dummy clk_get_rate() routine which is being used by cpufreq core. More dummy routines might be added later if there is a need for that.
Cc: Russell King linux@arm.linux.org.uk Cc: Arnd Bergmann arnd.bergmann@linaro.org Reported-by: <Olof Johansson> olof@lixom.net Signed-off-by: Viresh Kumar viresh.kumar@linaro.org --- Hi Rafael,
This is the only new part here. 2/2 is still the same. Its compiled for Assabet board. And the issue reported by Olof is resolved with it.

CPUFreq drivers that use clock frameworks interface,i.e. clk_get_rate(), to get CPUs clk rate, have similar sort of code used in most of them.
This patch adds a generic ->get() which will do the same thing for them. All those drivers are required to now is to set .get to cpufreq_generic_get() and set their clk pointer in policy->clk during ->init().
