* A CPU clock is defined as a clock supplied to a CPU or a group of CPUs.
* The CPU clock is typically derived from a hierarchy of clock
* blocks which includes mux and divider blocks. There are a number of other
* auxiliary clocks supplied to the CPU domain such as the debug blocks and AXI
* clock for CPU domain. The rates of these auxiliary clocks are related to the
* CPU clock rate and this relation is usually specified in the hardware manual
* of the SoC or supplied after the SoC characterization.
*
* The below implementation of the CPU clock allows the rate changes of the CPU
* clock and the corresponding rate changes of the auxillary clocks of the CPU
* domain. The platform clock driver provides a clock register configuration
* for each configurable rate which is then used to program the clock hardware
* registers to acheive a fast co-oridinated rate change for all the CPU domain
* clocks.
*
* On a rate change request for the CPU clock, the rate change is propagated
* upto the PLL supplying the clock to the CPU domain clock blocks. While the
* CPU domain PLL is reconfigured, the CPU domain clocks are driven using an
* alternate clock source. If required, the alternate clock source is divided
* down in order to keep the output clock rate within the previous OPP limits.
