833ee5c4ab drm/radeon/kms: remove rs4xx gart limit
We used to limit the rs4xx gart aperture to 32 MB, but I suspect
that was due to not meeting the alignment requirements of the
aperture.  This patch should only be applied after:
"drm/radeon/kms: fix gtt MC base alignment on rs4xx/rs690/rs740 asics"
has been applied.

This patch should probably soak for a bit in d-r-t.

167ffc44ca drm: radeon: fix sign bug
The "error" variable is unsigned so it's never less than zero.  I
changed it to check if (freq < current_freq) directly.

"best_error" is also unsigned so "best_error - 100" could be a large
number instead of a negative.  Since "error" is unsigned it is never
less than a negative and so the cases where "best_error" is less than or
equal to 100 are false.

4c712e6c7e drm/radeon/kms: check/restore sanity before doing anything else with GPU.
On systems using kexec, the new kernel is booted straight from the old kernel, without any warning to the graphics driver. So the GPU is basically left as-is in a running state, however the CPU side is completly reset.

Without stating the saneness of anyone using kexec on live systems, we should at least try not to crash the GPU. This patch resets 3 registers to 0 that could cause bad things to happen to the running system.

This allows kexec to work on a Power6/RN50 system.

29508eb66b drm/radeon/kms: drop taking lock around crtc lookup.
We only add/remove crtcs at driver load, you cannot remove when
the GPU is running a CS packet since the fd is open, when
GPU hotplugging on radeons actually is needed all this locking
needs a review and I've started re-working kms core locking to deal
with this better. But for now avoid long delays in CS processing when
hotplug detect is happening in a different thread.

this fixes a regression introduced with hotplug detection.

37f9003bd3 drm/radeon/kms/atom: add crtc disable function
Disables the crts as per dpms and also disables the ppll
associated with the crtc.  This should save additional power.

90c1efdd12 drm: Return EBUSY if the framebuffer is unbound when flipping.
It looks like there is a race condition between unbinding a framebuffer
on a hotplug event and user space trying to flip:

92897b5c66 drm: add "auto" dithering method
There's no convenient/reliable way for drivers to both obey the dithering
mode property, and to be able to attempt to provide a good default in all
cases.

This commit adds an "auto" method to the property which drivers can default
to if they wish, whilst still allowing the user to override the choice as
they do now.
