	If the common clock framework is enabled, call of_clk_init(NULL) in time_init() to register device tree clocks with the clock framework. After this time_init() calls a new function init_metag_clocks(), which looks for a clock named "core" in the node compatible with "img,meta" (usually the root node). If found the get_core_freq machine callback is overridden to obtain the core clock frequency using that clock.

2013-03-02	metag: Time keeping	James Hogan	1	-0/+51
	Add time keeping code for metag. Meta hardware threads have 2 timers. The background timer (TXTIMER) is used as a free-running time base, and the interrupt timer (TXTIMERI) is used for the timer interrupt. Both counters traditionally count at approximately 1MHz.
