815 * clock rate is 10 times the DPLL clock. At low resolution/refresh rate
816 * modes, the bus rate would be below the limits, so SDVO allows for stuffing
817 * dummy bytes in the datastream at an increased clock rate, with both sides of
818 * the link knowing how many bytes are fill.
820 * So, for a mode with a dotclock of 65Mhz, we would want to double the clock
821 * rate to 130Mhz to get a bus rate of 1.30Ghz. The DPLL clock rate would be
822 * set to 130Mhz, and the SDVO multiplier set to 2x in this register and
