73db4bedc5 drm/nouveau: don't execute INIT_GPIO unless we're really running the table
This resulted in accidently switching off the eDP panel on certain laptops
since the default state in the GPIO table was off.

Fixes rh#582621

d13102c6b4 drm/nouveau: fix POST detection for certain chipsets
We totally fail at detecting un-POSTed chipsets prior to G80.  This commit
changes the pre-G80 POST detection to read the programmed horizontal total
from CRTC 0, and assume the card isn't POSTed if it's 0.

NVIDIA use some other heuristics more similar to what we do on G80, but I
wasted quite a long time trying to figure out the exact specifics of what
they do so we can try this for a bit instead.

We may not have parsed the entry yet if the i2c_index is for an i2c bus

This could be done oh so much more nicely, except we have to care about

4bff51711c drm/radeon/kms/pm: fix r6xx+ profile setup
This patch is a combination of the previous two profile
patches, but without the index bugs.  It cleans up and
fixes some issues with pm profile setup on r6xx chips.
Some tables have different orderings for the power states,
also, r600 only has 1 clock mode per power state. On
desktop cards there are no battery modes, so the low and high
power states are the same.  For the low profile case, choose
the lower clock mode.

ce8f53709b drm/radeon/kms/pm: rework power management
- Separate dynpm and profile based power management methods.  You can select the pm method
  by echoing the selected method ("dynpm" or "profile") to power_method in sysfs.
- Expose basic 4 profile in profile method
  "default" - default clocks
  "auto" - select between low and high based on ac/dc state
  "low" - DC, low power mode
  "high" - AC, performance mode
  The current base profile is "default", but it should switched to "auto" once we've tested
  on more systems.  Switching the state is a matter of echoing the requested profile to
  power_profile in sysfs.  The lowest power states are selected automatically when dpms turns
  the monitors off in all states but default.
- Remove dynamic fence-based reclocking for the moment.  We can revisit this later once we
  have basic pm in.
- Move pm init/fini to modesetting path.  pm is tightly coupled with display state.  Make sure
  display side is initialized before pm.
- Add pm suspend/resume functions to make sure pm state is properly reinitialized on resume.
- Remove dynpm module option.  It's now selectable via sysfs.

a424816fb3 drm/radeon/kms/pm: rework power management
Add two new sysfs attributes:
- dynpm
- power_state

Echoing 0/1 to dynpm disables/enables dynamic power management.
The driver scales the sclk dynamically based on the number of
queued fences.  dynpm only scales sclk dynamically in single head
mode.

Echoing x.y to power_state selects a static power state (x) and clock
mode (y).  This allows you to statically select a power state and clock
mode.  Selecting a static clock mode will disable dynpm.
