For Linux to be able to work out how fast its clocks are going, so that timer ticks come approximately at the right time, it needs to be able to query the clock control module (CCM). This is the start of a CCM implementation. It currently knows only about the MCU, HSP and IPG clocks --- i.e., the ones used to feed the periodic and general purpose timers.
