Now that we've eliminated INTEL_GEN(), IS_GEN_RANGE(), etc. from the
display code, we should also kill off our use of the IS_GEN9_* macros
too. We'll do the conversion manually this time instead of using
Coccinelle since the most logical substitution can depend heavily on the
code context, and sometimes we can keep the code simpler if we make
additional adjustments such as swapping the order of if/else arms.

Atm the driver will calculate a wrong MST timeslots/MTP (aka time unit)
value for MST streams if the link parameters (link rate or lane count)
are limited in a way independent of the sink capabilities (reported by
DPCD).
One example of such a limitation is when a MUX between the sink and
source connects only a limited number of lanes to the display and
connects the rest of the lanes to other peripherals (USB).
Another issue is that atm MST core calculates the divider based on the
backwards compatible DPCD (at address 0x0000) vs. the extended
capability info (at address 0x2200). This can result in leaving some
part of the MST BW unused (For instance in case of the WD19TB dock).
Fix the above two issues by calculating the PBN divider value based on
the rate and lane count link parameters that the driver uses for all
other computation.

This reverts commit 0883ce8146. Originally
these quirks were added because of the issues with using the eDP
backlight interfaces on certain laptop panels, which made it impossible
to properly probe for DPCD backlight support without having a whitelist
for panels that we know have working VESA backlight control interfaces
over DPCD. As well, it should be noted it was impossible to use the
normal sink OUI for recognizing these panels as none of them actually
filled out their OUIs, hence needing to resort to checking EDIDs.
At the time we weren't really sure why certain panels had issues with
DPCD backlight controls, but we eventually figured out that there was a
second interface that these problematic laptop panels actually did work
with and advertise properly: Intel's proprietary backlight interface for
HDR panels. So far the testing we've done hasn't brought any panels to
light that advertise this interface and don't support it properly, which
means we finally have a real solution to this problem.
As a result, we now have no need for the force DPCD backlight quirk, and
furthermore this also removes the need for any kind of EDID quirk
checking in DRM. So, let's just revert it for now since we were the only
driver using this.

So far, max dot clock rate for MST mode rely on physcial
bandwidth limitation. It would caused compatibility issue
if source display resolution exceed MST hub output ability.
For example, source DUT had DP 1.2 output capability.
And MST docking just support HDMI 1.4 spec. When a HDMI 2.0
monitor connected. Source would retrieve EDID from external
and get max resolution 4k@60fps. DP 1.2 can support 4K@60fps
because it did not surpass DP physical bandwidth limitation.
Do modeset to 4k@60fps, source output display data but MST
docking can't output HDMI properly due to this resolution
already over HDMI 1.4 spec.
Refer to commit <fcf463807596> ("drm/dp_mst: Use full_pbn
instead of available_pbn for bandwidth checks").
Source driver should refer to full_pbn to evaluate sink
output capability. And filter out the resolution surpass
sink output limitation.
Changes since v1:
* Using mgr->base.lock to protect full_pbn.
Changes since v2:
* Add ctx lock.
Changes since v3:
* s/intel_dp_mst_mode_clock_exceed_pbn_bandwidth/
intel_dp_mst_mode_clock_exceeds_pbn_bw/
* Use the new drm_connector_helper_funcs.mode_valid_ctx to properly pipe
down the drm_modeset_acquire_ctx that the probe helpers are using, so
we can safely grab &mgr->base.lock without deadlocking
Changes since v4:
* Move drm_dp_calc_pbn_mode(mode->clock, bpp, false) > port->full_pbn
check
* Fix the bpp we use in drm_dp_calc_pbn_mode()
* Drop leftover (!mgr) check
* Don't check for if full_pbn is unset. To be clear - it _can_ be unset,
but if it is then it's certainly a bug in DRM or a non-compliant sink
as full_pbn should always be populated by the time we call
->mode_valid_ctx.
We should workaround non-compliant sinks with full_pbn=0, but that
should happen in the DP MST helpers so we can estimate the full_pbn
value as best we can.

During encoder enabling we clear the flag before starting the ACT
sequence and wait for the flag, but the clearing is missing during
encoder disabling, add it there too. Since nothing cleared the flag
automatically we could've run subsequent disabling steps too early.

During transcoder enabling we'll configure the transcoder in MST mode
and enable the VC payload allocation, which will start the ACT sequence.
Before waiting for the ACT sequence completion, we need to clear the ACT
sent flag, but based on the above we can do this right before enabling
the transcoder.
For clarity, move the flag clearing closer to where we wait for it.
While at it also factor out some common code.

(cherry picked from commit c980216dd2)
Signed-off-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com>
Some TypeC -> native DP adapters, at least the Club 3D CAC-1557 adapter,
incorrectly filter out HPD short pulses with a duration less than
~540 usec, leading to MST probe failures.
According to the DP Standard 2.0 section 5.1.4:
- DP sinks should generate short pulses in the 500 usec -> 1 msec range
- DP sources should detect short pulses in the 250 usec -> 2 msec range
According to the DP Alt Mode on TypeC Standard section 3.9.2, adapters
should detect and forward short pulses according to how sources should
detect them as specified in the DP Standard (250 usec -> 2 msec).
Based on the above filtering out short pulses with a duration less than
540 usec is incorrect.
To make such adapters work add support for a driver polling on MST
inerrupt flags, and wire this up in the i915 driver. The sink can clear
an interrupt it raised after 110 msec if the source doesn't respond, so
use a 50 msec poll period to avoid missing an interrupt. Polling of the
MST interrupt flags is explicitly allowed by the DP Standard.
This fixes MST probe failures I saw using this adapter and a DELL U2515H
monitor.
v2:
- Fix the wait event timeout for the no-poll case.
v3 (Ville):
- Fix the short pulse duration limits in the commit log prescribed by the
DP Standard.
- Add code comment explaining why/how polling is used.
- Factor out a helper to schedule the port's hpd irq handler and move it
to the rest of hotplug handlers.
- Document the new MST callback.

Drive-by fix I noticed the other day - drm_dp_mst_has_audio() only ever
made sense back when we still had to validate ports before accessing
them in order to (attempt to) avoid NULL dereferences. Since we have
proper reference counting that guarantees we always can safely access
the MST port, there's no use in keeping this function around as all it
does is validate the port pointer before checking the audio status.
Note - drm_dp_mst_port->has_audio is technically protected by
drm_device->mode_config.connection_mutex, since it's only ever updated
from drm_dp_mst_get_edid(). Additionally, we change the declaration for
port in struct intel_connector to be properly typed, so we can directly
access it.
Changes since v1:

the atomic state all the way down.
The alternative would be yet another encoder hook which we'll
have to call after all the normal modeset stuff is done. Not
really a fan of yet another hook just for this.
Note that during readout state sanitation we are now going
to pass NULL as the atomic state since we don't have one.
We need to change that and then we can also s/crtc_state/crtc/

drm_dp_mst_topology_mgr_cbs.destroy_connector callbacks are identical
amongst every driver and don't do anything other than cleaning up the
connector((drm_connector_unregister()/drm_connector_put())) except for
amdgpu_dm driver where some amdgpu_dm specific code in there.
This connector cleaning up is now being handled in the drm core so
driver destroy_connector callbacks are not needed (except for
amdgpu_dm) hence remove them.
Removal is done with below sementic patch:
@r1@
identifier func, E;
@@
struct drm_dp_mst_topology_cbs E = {
...,
- .destroy_connector = func
};
@delete depends on r1@
identifier r1.func;

drm_dp_mst_port_add_connector() directly calls the
drm_connector_register() now and
drm_dp_mst_topology_mgr_cbs.register_connector callback is not getting
called anymore.
Hence remove all drm_dp_mst_topology_mgr_cbs.register_connector
callbacks.
This is the preparatory step for removing the
drm_dp_mst_topology_mgr_cbs.register_connector callback hook.
The removal is done with below sementic patch:
@r1@
identifier func, E;
@@
struct drm_dp_mst_topology_cbs E = {
...,
- .register_connector = func
};
@delete depends on r1@

i915 can enable aux device nodes for DP MST by calling
drm_dp_mst_connector_late_register()/
drm_dp_mst_connector_early_unregister(),
so let's hook that up.
Changes since v1:
* Call intel_connector_register/unregister() from
intel_dp_mst_connector_late_register/unregister() so we don't lose
error injection - Ville Syrjälä
Changes since v2:
* Don't forget to clean up if intel_connector_register() fails - Ville
