- * The way that the Blackfin core timer works is:
- * - CCLK is divided by a programmable 8-bit pre-scaler (TSCALE)
- * - Every time TSCALE ticks, a 32bit is counted down (TCOUNT)
- *
- * If you take the fastest clock (1ns, or 1GHz to make the math work easier)
- * 10ms is 10,000,000 clock ticks, which fits easy into a 32-bit counter
- * (32 bit counter is 4,294,967,296ns or 4.2 seconds) so, we don't need
- * to use TSCALE, and program it to zero (which is pass CCLK through).
- * If you feel like using it, try to keep HZ * TIMESCALE to some
- * value that divides easy (like power of 2).
