This framework is widely used with +System-On-Chip (SOC) platforms to support power management and various +devices which may need custom clock rates. Note that these "clocks" +don't relate to timekeeping or real time clocks (RTCs), each of which +have separate frameworks. These :c:type:`struct clk ` +instances may be used to manage for example a 96 MHz signal that is used +to shift bits into and out of peripherals or busses, or otherwise +trigger synchronous state machine transitions in system hardware. + +Power management is supported by explicit software clock gating: unused +clocks are disabled, so the system doesn't waste power changing the +state of transistors that aren't in active use. On some systems this may +be backed by hardware clock gating, where clocks are gated without being +disabled in software. Sections of chips that are powered but not clocked +may be able to retain their last state. This low power state is often +called a *retention mode*. This mode still incurs leakage currents, +especially with finer circuit geometries, but for CMOS circuits power is +mostly used by clocked state changes. + +Power-aware drivers only enable their clocks when the device they manage +is in active use.
