| | * | | | | drm/nouveau/i2c: create proper chipset-specific class implementationsBen Skeggs2013-02-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
| | * | | | | drm/nv50-/disp: 0x0000 is a valid udisp config valueBen Skeggs2013-02-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Return an out-of-range value instead to signal a failure from exec_clkcmp(). Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
| | * | | | | drm/nv50/devinit: reverse the logic for running encoder init scriptsBen Skeggs2013-02-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A single U encoder table can match multiple DCB entries, whereas the reverse is not true and can lead to us not matching a DCB entry at all, and fail to initialise some encoders.

| | * | | | | drm/nouveau/bios: store a type/mask hash in parsed dcb dataBen Skeggs2013-02-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Matches format used by a couple of other vbios tables, useful to have laying around already calculated. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
| | * | | | | drm/nouveau/i2c: extend type to 16-bits, add lookup-by-type functionBen Skeggs2013-02-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For off-chip transmitters we won't necessarily have an i2c table entry to lookup, but we can do it instead by encoding the type to include the extdev type and looking that up instead.

| | * | | | | drm/nouveau: store i2c port pointer directly in nouveau_encoderBen Skeggs2013-02-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is about to become somewhat more complicated to determine in a number of cases, so store the "common" case (DDC/AUX) directly inside the encoder structure. Pre-nv50 code not touched except to fill the pointer, don't care. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
| | * | | | | drm/nouveau/i2c: handle i2c/aux mux outside of port lookup functionBen Skeggs2013-02-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Not quite how I want it yet, but, I'll fix that at some point. For right now, it's needed because find() won't necessarily be used right before a transaction anymore. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
| | * | | | | drm/nv50/graph: avoid touching 400724, it doesn't existBen Skeggs2013-02-20
