+ * \brief System Resources
+ *
+ * System resource provides interface to device drivers to list possible
+ * configurations that can be changed by system to minimize (optimize)
+ * energy and power usage, to lock a specific resource, fixing it at
+ * desired value and to support multiple power down capabilities by the
+ * up_idle().
+ *
+ * System resources are provided on the chip or board level, such as:
+ * - clock scaling (chip level)
+ * - voltage scaling (board level)
+ *
+ * This interface is to be used by low-level peripherals only and its
+ * purpose is to be as fast as possible to do quick power and energy
+ * optimizations (including deep power savings).
+ *
+ * A separate common device driver interface would be required to allow
+ * access from user programs (i.e. to select voltage and similar).

+/** Enable resource: clock scaling, allocates an array of options bits
+ * for each peripheral. On STM32 this option adds about 64-128 bytes.
+ * This option is provided by chip: nuttx/arch/board/resource.h
+ *
+ * Clock resources are used by low-level driver before they starts a
+ * transaction. System may pick up any of the clock options that suit
+ * all of the drivers. The selected clock option is returned, and is up
+ * to the driver to recalculate and modify i.e. period or additional
+ * prescaler to achieve the desired frequency of operation. After lock()
+ * call, clock will not change, until unlock() is called.
+ *
+ * As long there is a single clock lock, system will not be able to
+ * enter low power-down mode in which all of the clocks are disabled.
+ *
+ * The isactive() function is called typically by the up_idle() to
+ * decide which power-down mode to select. If none of the clocks are
+ * required to run, then ultra low power-down mode can be entered,
+ * reducing power as low as downto 35 uA or 25 uA (with LDO in low-power
+ * mode).
+ *
+ * Note: AD may continue to consume power in stop mode, so it's up
+ * to AD driver to disable its power when its unused.
