13 * A simple timer driver providing synchronous delay functionality.
14 * The driver must be initialized with a structure that provides a
15 * function pointer to return the timer value and a clock
16 * multiplier/divider. The ratio of the multiplier and the divider is
Juan Castillofd383b42015-12-01 16:10:15 +000017 * the clock period in microseconds.
