SDVO_HDMIC_ENABLE_DIGITAL_DISPLAY_PORT_C_ENABLE:
Disabling this port
will put it in its lowest power state. Port enable takes place on the Vblank after being
written. Both this bit and bit 6 of this register must be enabled to send audio over this
port in HDMI. This port must not be enabled simultaneously with DisplayPort C.
[DevIBX] When disabling the port, software must temporarily enable the port with
transcoder select (bit #30) cleared to 0 after disabling the port. This is workaround for
hardware issue where the transcoder select set to 1 will prevent DPC from being
enabled on transcoder A.
[DevIBX] Software must write this bit twice when enabling the port (setting to 1 ) as a
workaround for hardware issue that may result in first write getting masked.
[DevIBX] Toggle this bit off then on at the end of mode set sequence when enabling
HDMI 12-bit per color with pixel repeat.
1 = Enable. This bit enables the Digital Display Port C interface for HDMI or DVI modes.
0 = Disable and tristates the Digital Display Port C interface for HDMI or DVI modes.

PIPE_SELECT:
This bit determines from which display pipe the source data will
originate. This only applies to devices with dual display pipes. Pipe selection takes place
on the Vblank after being written
0 = Pipe A
1 = Pipe B

RESERVED:
[DevCDV]:
stall Select: This bit selects stall for external scaling functionality only on SDVO.
Programming notes: It is only valid to have a single stall indication to a particular pipe.
In cases where two ports are being driven from a single pipe, one of the ports must set
this bit to 0. Only sDVOB or sDVOC can select the stall function, as only a single stall
input is available between the two interfaces.
Set the stall input to unused before programming the external device creating the stall.
0 = Stall input signal is unused on this port
1 = Stall input signal is used to stall the pipe attached to this port
