* drm/radeon/kms: use hardcoded dig encoder to transmitter mapping for DCE4.1Alex Deucher2011-10-06
| | | | | | | | | | | | | | 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 channel_remap setup (v2)Alex Deucher2011-10-04
| | | | | | | | | | | | | | | | | | | Most asics just use the hw default value which requires no explicit programming. For those that need a different value, the vbios will program it properly. As such, there's no need to program these registers explicitly in the driver. Changing MC_SHARED_CHREMAP requires a reload of all data in vram otherwise its contents will be scambled.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I was seeing a nasty 5 frame glitch every 10 seconds, caused by the poll for connection on DVI attached by SDVO. As my SDVO DVI supports hotplug detect interrupts, the fix is to enable them, and hook them in to the various bits of driver infrastructure so that they work reliably. Note that this is only tested on single-function DVI-D SDVOs, on two platforms (965GME and 945GSE), and has not been checked against a specification document.
