461 * SDVO/UDI pixel multiplier.
463 * SDVO requires that the bus clock rate be between 1 and 2 Ghz, and the bus
464 * clock rate is 10 times the DPLL clock. At low resolution/refresh rate
465 * modes, the bus rate would be below the limits, so SDVO allows for stuffing
466 * dummy bytes in the datastream at an increased clock rate, with both sides of
467 * the link knowing how many bytes are fill.
469 * So, for a mode with a dotclock of 65Mhz, we would want to double the clock
470 * rate to 130Mhz to get a bus rate of 1.30Ghz. The DPLL clock rate would be
471 * set to 130Mhz, and the SDVO multiplier set to 2x in this register and
472 * through an SDVO command.
474 * This register field has values of multiplication factor minus 1, with
