Currently in nouveau_connector_ddc_detect() and
nouveau_connector_detect_lvds(), we start the connector probing process
by releasing the previous EDID and informing DRM of the change. However,
since commit 5186421cbfe2 ("drm: Introduce epoch counter to
drm_connector")
Since other drivers are also going to need to be aware of the sink count
in order to do proper dongle detection, we might as well steal i915's
DP_SINK_COUNT helpers and move them into DRM helpers so that other
dirvers can use them as well.
Note that this also starts using
For whatever reason we currently unset the EDID for DP CEC support when
responding to the connector being unplugged, instead of just doing it in
nouveau_connector_detect() where we set the CEC EDID. This isn't really
needed and could even potentially cause us to forget to unset the EDID
if the
This is another bit that we never implemented for nouveau: dongle
detection. When a "dongle", e.g. an active display adaptor, is hooked up
to the system and causes an HPD to be fired, we don't actually know
whether or not there's anything plugged into the dongle without checking
the sink count. As

Actually, now I wonder if we really should have tried to handle the
wrong-way cow reuse case some other way entirely.

Now that we've extracted i915's code for reading both the normal DPCD
caps and extended DPCD caps into a shared helper, let's start using this
in nouveau to enable us to start checking extended DPCD caps for free.

And of course, we'll also need to read the sink count from other drivers
as well if we're checking whether or not it's supported. So, let's
extract the code for this into another helper.

Since DP 1.3, it's been possible for DP receivers to specify an
additional set of DPCD capabilities, which can take precedence over the
capabilities reported at DP_DPCD_REV.
Basically any device supporting DP is going to need to read these in an
identical manner, in particular nouveau, so let's
We're going to be doing the same probing process in nouveau for
determining downstream DP port capabilities, so let's deduplicate the
work by moving i915's code for handling this into a shared helper:
drm_dp_downstream_read_info().
Note that when we do this, we also do make some functional
This adds support for querying the maximum clock rate of a downstream
port on a DisplayPort connection. Generally, downstream ports refer to
active dongles which can have their own pixel clock limits.
Note as well, we also start marking the connector as disconnected if we
can't read the DPCD,
Just a tiny drive-by cleanup, we can consolidate i915's code for
checking for MST support into a helper to be shared across drivers.

Currently we perform both short IRQ handling for DP, and connector
reprobing in the HPD IRQ handler. However since we need to grab
connection_mutex in order to reprobe a connector, in theory we could
accidentally block ourselves from handling any short IRQs until after a
modeset completes if a
Since fa3cdf8d0b09 ("drm/nouveau: Reset MST branching unit before
enabling") we've been clearing DP_MST_CTRL before we start enabling MST.
Since then clearing DP_MST_CTRL in nv50_mstm_new() has been unnecessary
and redundant, so let's remove it.

First some backstory here: Currently, we keep track of whether or not
we've enabled MST or not by trying to piggy-back off the MST helpers.
This means that in order to check whether MST is enabled or not, we
actually need to grab drm_dp_mst_topology_mgr.lock.
Back when I originally wrote this, I
Since this actually logs accesses, we should probably always be using
this imho…

While the way we find the associated connector for an encoder is just
fine for legacy modesetting, it's not correct for nv50+ since that uses
atomic modesetting. For reference, see the drm_encoder kdocs.
Fix this by removing nouveau_encoder_connector_get(), and replacing it

Noticed this while going through our DP code - we use an open-coded
version of drm_dp_read_desc() instead of just using the helper, so
change that. This will also let us use quirks in the future if we end up
needing them.
