+Basic C Library Functions
+=========================
+
+When writing drivers, you cannot in general use routines which are from
+the C Library. Some of the functions have been found generally useful
+and they are listed below. The behaviour of these functions may vary
+slightly from those defined by ANSI, and these deviations are noted in
+the text.

+Clock Framework
+===============
+
+The clock framework defines programming interfaces to support software
+management of the system clock tree. 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 <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. Also, system sleep states often differ according to
+which clock domains are active: while a "standby" state may allow wakeup
+from several active domains, a "mem" (suspend-to-RAM) state may require
+a more wholesale shutdown of clocks derived from higher speed PLLs and
+oscillators, limiting the number of possible wakeup event sources. A
+driver's suspend method may need to be aware of system-specific clock
+constraints on the target sleep state.
+
+Some platforms support programmable clock generators. These can be used
+by external chips of various kinds, such as other CPUs, multimedia
+codecs, and devices with strict requirements for interface clocking.
