* drm/radeon/kms: use hardcoded dig encoder to transmitter mapping for DCE4.1Alex Deucher2011-10-16
| | | | | | | | | | | | | | | | | commit cb7cf41961fe10773c491c75ae73539ad4bbed66 upstream. The encoders are supposedly fully routeable, but changing the mapping doesn't always seem to take. Using a hardcoded mapping is much more reliable.

* drm/radeon/kms: fix DDIA enable on some rs690 systemsAlex Deucher2011-10-03
| | | | | | | | | | | | | | commit fdfc61594e6de21c23f955818ef78bcab9bafe40 upstream. DVOOutputControl checks the value of of bios scratch reg 3 on some tables and assumes the encoder is already enabled if the DFP2_ACTIVE bit is set. Clear that bit so the table sets the DDIA enable bit properly.

* drm/radeon/kms: add missing param for dce3.2 DP transmitter setupAlex Deucher2011-06-19

* drm/radeon/kms/atom: fix duallink on some early DCE3.2 cardsAlex Deucher2011-06-19
| | | | | | | | | | | | | | | Certain revisions of the vbios on DCE3.2 cards have a bug in the transmitter control table which prevents duallink from being enabled properly on some cards. The action switch statement jumps to the wrong offset for the OUTPUT_ENABLE action. The fix is to use the ENABLE action rather than the OUTPUT_ENABLE action on the affected cards. In fixed version of the vbios, both actions jump to the same offset, so the change should be safe.

The encoder isn't necessary for PHY init so just assign to 0 for init so that the table is executed.
