232 * SDVO/UDI pixel multiplier.
234 * SDVO requires that the bus clock rate be between 1 and 2 Ghz, and the bus
235 * clock rate is 10 times the DPLL clock. At low resolution/refresh rate
236 * modes, the bus rate would be below the limits, so SDVO allows for stuffing
237 * dummy bytes in the datastream at an increased clock rate, with both sides of
238 * the link knowing how many bytes are fill.
240 * So, for a mode with a dotclock of 65Mhz, we would want to double the clock
241 * rate to 130Mhz to get a bus rate of 1.30Ghz. The DPLL clock rate would be
242 * set to 130Mhz, and the SDVO multiplier set to 2x in this register and
243 * through an SDVO command.
