There is a prototype for this function in the header, but the function
itself lacks a 'void' in the argument list, causing a harmless warning
when building with 'make W=1':

As with vga_init, this function doesn't make sense on non-PCI devices,
and the Thunderbolt check in it dereferences a NULL pointer in that
case. Add some code to skip this function when the device is not a PCI
device.

On Tegra186, powergating is handled by the BPMP power domain provider
and the "legacy" powergating API is not available. Therefore skip
these calls if we are attached to a power domain.

This patch creates a special group attributes for attrs like "*auto_point*".
We check if we have support for them, and if we do, we gather them all in
an attribute_group's structure which is the parameter regarding special groups
of hwmon_device_register_with_info
We also do the same for pwm_min/max attrs.

This patch introduces the nouveau_hwmon_ops structure, sets up
.is_visible and .read_string operations and adds all the functions
for these operations.
This is also a preparation for the next patches, where most of the
work is being done.
This code doesn't interacture with the old one.
It's just to make easier the review of all patches.

These exist to give NVKM information on the set of display paths that
the DD needs to be active at any given time.
Previously, the supervisor attempted to determine this solely from OR
state, but there's a few configurations where this information on its
own isn't enough to determine the specific display paths in question:
- ANX9805, where the PIOR protocol for both DP and TMDS is TMDS.
- On a device using DCB Switched Outputs.
- On GM20x and newer, with a crossbar between the SOR and macro links.
After this commit, the DD tells NVKM *exactly* which display path it's
attempting a modeset on.

All of the necessary hw-specific logic is now handled at the output
resource level, so all of this can go away.

Also removes the user-facing methods to these controls, as they're not

This essentially (unless the link becomes unstable and needs to be
re-trained) gives us a single entry-point to link training, during
supervisor handling, where we can ensure all routing is up to date.

An upcoming commit will limit link training to only when the sink is
meant to be displaying an image.
We still need IRQs enabled even when the link isn't trained (for MST
messages), but don't want to train the link unnecessarily.

The aim here is to protect the OR against locking up when something
unexpected happens (such as the display disappearing during modeset,
or the DD misbehaving).
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
This struct doesn't hold link configuration data anymore, so we can
limit its use to internal DP training (anx9805 handles training for
external DP).

This hasn't been used since atomic.
We may want to re-implement "fast" DPMS at some point, but for now,

This essentially replicates our current behaviour in a way that's
compatible with the new model that's emerging, so that we're able

Upcoming commits make supervisor handling share code between the NV50
and GF119 implementations. Because of this, and a few other cleanups,

In order to properly support the SOR -> SOR + pad macro separation
that occurred with GM20x GPUs, we need to separate OR handling out
of the output path code.
This will be used as the base to support ORs (DAC, SOR, PIOR).

Primarily intended as a way to pass per-head state around during

This is to allow hw-specific code to instantiate output resources first,
