+ * See \ref sysclk_quickstart.
+ *
+ * The <em>sysclk</em> API covers the <em>system clock</em> and all
+ * clocks derived from it. The system clock is a chip-internal clock on
+ * which all <em>synchronous clocks</em>, i.e. CPU and bus/peripheral
+ * clocks, are based. The system clock is typically generated from one
+ * of a variety of sources, which may include crystal and RC oscillators
+ * as well as PLLs.  The clocks derived from the system clock are
+ * sometimes also known as <em>synchronous clocks</em>, since they
+ * always run synchronously with respect to each other, as opposed to
+ * <em>generic clocks</em> which may run from different oscillators or
+ * PLLs.
+ *
+ * Most applications should simply call sysclk_init() to initialize
+ * everything related to the system clock and its source (oscillator,
+ * PLL or DFLL), and leave it at that. More advanced applications, and
+ * platform-specific drivers, may require additional services from the
+ * clock system, some of which may be platform-specific.
+ *
+ * \section sysclk_group_platform Platform Dependencies
+ *
+ * The sysclk API is partially chip- or platform-specific. While all
+ * platforms provide mostly the same functionality, there are some
+ * variations around how different bus types and clock tree structures
+ * are handled.
+ *
+ * The following functions are available on all platforms with the same
+ * parameters and functionality. These functions may be called freely by
+ * portable applications, drivers and services:
+ *   - sysclk_init()
+ *   - sysclk_set_source()
+ *   - sysclk_get_main_hz()
+ *   - sysclk_get_cpu_hz()
+ *   - sysclk_get_peripheral_bus_hz()
+ *
+ * The following functions are available on all platforms, but there may
+ * be variations in the function signature (i.e. parameters) and
+ * behavior. These functions are typically called by platform-specific
+ * parts of drivers, and applications that aren't intended to be
+ * portable:
+ *   - sysclk_enable_peripheral_clock()
+ *   - sysclk_disable_peripheral_clock()
+ *   - sysclk_enable_module()
+ *   - sysclk_disable_module()
+ *   - sysclk_module_is_enabled()
+ *   - sysclk_set_prescalers()
+ *
+ * All other functions should be considered platform-specific.
+ * Enabling/disabling clocks to specific peripherals as well as
+ * determining the speed of these clocks should be done by calling
+ * functions provided by the driver for that peripheral.
