29fb52ca78 drm/radeon/kms: expose thermal/fan i2c buses
Look up i2c bus in the power table and expose it.
You'll need to load a hwmon driver for any chips
on the bus, this patch just exposes the bus.

839461d3b0 drm/radeon/kms: switch to condition waiting for reclocking
We tried to implement interruptible waiting with timeout (it was broken
anyway) which was not a good idea as explained by Andrew. It's possible
to avoid using additional variable but actually it inroduces using more
complex in-kernel tools. So simply add one variable for condition.

9038dfdf69 drm/radeon/kms: simplify storing current and requested PM mode
We kept pointers to requested and current clock modes in every power state.
That was useless, more /global/ pointers in power struct are enough.

f735261baa [rfc] drm/radeon/kms: pm debugging check for vbl.
This patch adds a check on avivo chips to see if we are in the VBL
region for the active crtcs when we trigger the engine change.

I appear to have glitches locally on pm transistion (not sure all
fixes are in yet) and this at least seems to be correct here,
maybe others can test on systems with no glitches.

This already simplifies code significally and makes it maintaible
in case of adding memory reclocking plus voltage changing in future.

0ec0e74f78 drm/radeon/kms: add a power state type based on power state flags
The idea is to flag a power state with a certain type and use
that type to decide on what state to select.  On r6xx+, we
select a state and then transition between clock modes in that
state.  On pre-r6xx, we transition between states directly.

56278a8eda drm/radeon/kms: pull power mode info from bios tables (v3)
The general idea is to validate the current hw state
against the set of power states and select a power
state based on that.  This patch just pulls the power
states from the bios and prints the information.  It
is not currently hooked up in the actual power management
code.  Hooking it up will require reworking the the current
power state selection code and will be handled in a future
patch.

Additionally, we'd need to decide on some default lower
power states for cards without power tables.

v2 - increment state_index after checking for default state
v3 - fix typo in pm init on pre-atom cards, handle pre-atom
cards without x86 bioses

V2: reorganize functions, fix modesetting calls
V3: rebase patch, use radeon's workqueue
V4: enable on tested chipsets only, request VBLANK IRQs
V5: enable PM on older hardware (IRQs, mode_fixup, dpms)
V6: use separate dynpm module parameter
V7: drop RADEON_ prefix, set minimum mode for dpms off
V8: update legacy encoder call, fix order in rs600 IRQ
V9: update compute_clocks call in legacy, not only DPMS_OFF
