Nothing terribly exciting in here probably: - reworked thermal stuff from mupuf/I, has a chance of possibly working well enough when we get to being able to reclock.. - driver will report mmio access faults on chipsets where it's supported - will now sleep waiting on fences on nv84+ rather than polling - some cleanup of the internal fencing, looking towards sli/dmabuf sync - initial support for anx9805 dp/tmds encoder - nv50+ display fixes related to the above, and also might fix a few other issues - nicer error reporting (will log process names with channel errors) - various other random fixes * 'drm-nouveau-next' of git://anongit.freedesktop.org/git/nouveau/linux-2.6: (87 commits) nouveau: ACPI support depends on X86 and X86_PLATFORM_DEVICES drm/nouveau/i2c: add support for ddc/aux, and dp link training on anx9805 drm/nv50: initial kms support for off-chip TMDS/DP encoders drm/nv50-/disp: initial supervisor support for off-chip encoders drm/nv50-/disp: initial work towards supporting external encoders drm/nv50-/kms: remove unnecessary wait-for-completion points drm/nv50-/disp: move DP link training to core and train from supervisor drm/nv50-/disp: handle supervisor tasks from workqueue drm/nouveau/i2c: create proper chipset-specific class implementations drm/nv50-/disp: 0x0000 is a valid udisp config value drm/nv50/devinit: reverse the logic for running encoder init scripts drm/nouveau/bios: store a type/mask hash in parsed dcb data drm/nouveau/i2c: extend type to 16-bits, add lookup-by-type function drm/nouveau/i2c: aux channels not necessarily on nvio drm/nouveau/i2c: fix a bit of a thinko in nv_wri2cr helper functions drm/nouveau/bios: parse external transmitter type if off-chip drm/nouveau: store i2c port pointer directly in nouveau_encoder drm/nouveau/i2c: handle i2c/aux mux outside of port lookup function drm/nv50/graph: avoid touching 400724, it doesn't exist drm/nouveau: Fix DPMS 1 on G4 Snowball, from snow white to coal black. ...
