352/* The system time is maintained by a 64-bit counter comprised of the 32-bit
353 * SYSTIMH and SYSTIML registers. How the counter increments (and therefore
354 * its resolution) is based on the contents of the TIMINCA register - it
355 * increments every incperiod (bits 31:24) clock ticks by incvalue (bits 23:0).
356 * For the best accuracy, the incperiod should be as small as possible. The
357 * incvalue is scaled by a factor as large as possible (while still fitting
358 * in bits 23:0) so that relatively small clock corrections can be made.
359 *
360 * As a result, a shift of INCVALUE_SHIFT_n is used to fit a value of
361 * INCVALUE_n into the TIMINCA register allowing 32+8+(24-INCVALUE_SHIFT_n)
362 * bits to count nanoseconds leaving the rest for fractional nonseconds.
363 *
364 * Any given INCVALUE also has an associated maximum adjustment value. This
365 * maximum adjustment value is the largest increase (or decrease) which can be
366 * safely applied without overflowing the INCVALUE. Since INCVALUE has
367 * a maximum range of 24 bits, its largest value is 0xFFFFFF.
368 *
369 * To understand where the maximum value comes from, consider the following
370 * equation:
371 *
372 * new_incval = base_incval + (base_incval * adjustment) / 1billion
373 *
374 * To avoid overflow that means:
375 * max_incval = base_incval + (base_incval * max_adj) / billion
376 *
377 * Re-arranging:
378 * max_adj = floor(((max_incval - base_incval) * 1billion) / 1billion)
