The possible_crtcs mask needs to be a mask of CRTC indices. There is no
guarantee that the DRM indices match the hardware pipe number, so the
mask must be computed from the CRTC index.

Previously the struct bus_type exported by the host1x infrastructure was
only a very basic skeleton. Turn that implementation into a more full-
fledged bus to support proper probe ordering and power management.
Note that the bus infrastructure needs to be available before any of the
drivers can be registered. This is automatically ensured if all drivers
are built as loadable modules (via symbol dependencies). If all drivers
are built-in there are no such guarantees and the link order determines
the initcall ordering. Adjust drivers/gpu/Makefile to make sure that the
host1x bus infrastructure is initialized prior to any of its users (only
drm/tegra currently).

The atomic helpers rely on drm_atomic_state_clear() to reset an atomic
state if a retry is needed due to the w/w mutexes. The subsequent calls
to drm_atomic_get_{crtc,plane,...}_state() would then return the stale
pointers in state->{crtc,plane,...}_states.

For historical reasons going all the way back to how the Xrandr code
was implemented the semantics of the callbacks used to enable/disable
crtcs and encoders are ... interesting.
But with atomic helpers all that complexity has been binned, with only
a well-defined on/off action left. Unfortunately the names stuck.
Let's fix that by adding enable/disable hooks every, make them the
preferred variant for atomic and update documentations.
Later on we add debug warnings when drivers have deprecated hooks. But
while everything is in-flight with lots of drivers converting to
atomic that's a bit too much - better wait for things to settle a bit
first.

Cursor plane updates have historically been fully async and mutliple
updates batched together for the next vsync. And userspace relies upon
that. Since implementing a full queue of async atomic updates is a bit
of work lets just recover the cursor specific behaviour with a hint
flag and some hacks to drop the vblank wait.

This builds on top of the crtc->active infrastructure to implement

This is the infrastructure for DPMS ported to the atomic world.
Fundamental changes compare to legacy DPMS are:
- No more per-connector dpms state, instead there's just one per each
display pipeline. So if you clone either you have to unclone first
if you only want to switch off one screen, or you just switch of
everything (like all desktops do). This massively reduces complexity
for cloning since now there's no more half-enabled cloned configs to
consider.
- Only on/off, dpms standby/suspend are as dead as real CRTs. Again
reduces complexity a lot.
Now especially for backwards compat the really important part for dpms
support is that dpms on always succeeds (except for hw death and
unplugged cables ofc). Which means everything that could fail (like
configuration checking, resources assignments and buffer management)
must be done irrespective from ->active. ->active is really only a
toggle to change the hardware state. More precisely:
- Drivers MUST NOT look at ->active in their ->atomic_check callbacks.
Changes to ->active MUST always suceed if nothing else changes.
- Drivers using the atomic helpers MUST NOT look at ->active anywhere,
period. The helpers will take care of calling the respective
enable/modeset/disable hooks as necessary. As before the helpers
will carefully keep track of the state and not call any hooks
unecessarily, so still no double-disables or enables like with crtc
helpers.
- ->mode_set hooks are only called when the mode or output
configuration changes, not for changes in ->active state.
- Drivers which reconstruct the state objects in their ->reset hooks
or through some other hw state readout infrastructure must ensure
that ->active reflects actual hw state.
This just implements the core bits and helper logic, a subsequent
patch will implement the helper code to implement legacy dpms with
this.
v2: Rebase on top of the drm ioctl work:
- Move crtc checks to the core check function.
- Also check for ->active_changed when deciding whether a modeset
might happen (for the ALLOW_MODESET mode).
- Expose the ->active state with an atomic prop.
v3: Review from Rob
- Spelling fix in comment.
- Extract needs_modeset helper to consolidate the ->mode_changed ||
->active_changed checks.

We don't have full atomic modeset support yet, but the "nuclear
pageflip" subset of functionality (i.e., plane operations only) should
be ready. Allow the user to force atomic on for debug purposes, or for
fixed-purpose embedded devices that will only use atomic for plane
updates.
The term 'nuclear' is used here instead of 'atomic' to make it clear
that this doesn't allow full atomic modeset support, just a (very
useful) subset of the atomic functionality.
We'll drop the kernel parameter and unconditionally enable atomic in a
future patch once all of the necessary pieces are in.

Even though we only support atomic plane updates at the moment, we still
need to add an .atomic_get_property() entrypoint for connectors before
we allow the driver to flip on the DRIVER_ATOMIC bit. As soon as that
bit gets set, the DRM core will start adding atomic connector properties
(in addition to the plane properties we care about at the moment), so we
need to be able to handle the new way the DRM core will interact with
us.
For simplicity, we just lookup driver-specific connector properties in
the usual shadow array maintained by the core. Once we get real atomic
modeset support for crtc's and planes, this code should be re-written to
pull the data out of crtc/connector state structures.

We want to enable/test plane updates via the atomic interface, but as
soon as we flip DRIVER_ATOMIC on, the DRM core will take some atomic
codepaths to lookup properties during drmModeGetConnector() and some of
those codepaths unconditionally dereference connector->state
(specifically when looking up the CRTC ID property in
drm_atomic_connector_get_property()). Create a dummy connector state
for each connector at init time to ensure the DRM core doesn't try to
dereference a NULL connector->state. The actual connector properties
will never be updated or contain useful information, but since we're
doing this specifically for testing/debug of the plane operations (and
only when a specific kernel module option is given), that shouldn't
really matter.
Once we start creating connector states, the DRM core will want to be
able to clean them up for us. We also need to hook up the destruction
entrypoint to the core's helper.

Currently we don't call valleyview_set_rps() when changing the min/max

Eg. if the current frequency is at the old minimum, and then we reduce
the minum further we should then enable the 'down' interrupts in PMINTRMSK
but currently we don't.

Apart from calls as a result of GEM tracking to fb invalidate/flush, a

The call to fb_obj_invalidate (in flip) is placed before queuing flip for this
