Added epoch counter checking to intel_encoder_hotplug
in order to be able process all the connector changes,
besides connection status. Also now any change in connector
would result in epoch counter change, so no multiple checks
are needed.
v2: Renamed change counter to epoch counter. Fixed type name.
v3: Fixed rebase conflict
v4: Remove duplicate drm_edid_equal checks from hdmi and dp,
lets use only once edid property is getting updated and
increment epoch counter from there.
Also lets now call drm_connector_update_edid_property
right after we get edid always to make sure there is a
unified way to handle edid change, without having to
change tons of source code as currently
drm_connector_update_edid_property is called only in
certain cases like reprobing and not right after edid is
actually updated.
v5: Fixed const modifiers, removed blank line
v6: Removed drm specific part from this patch, leaving only
i915 specific changes here.

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.

On some platforms such as Elkhart Lake, although we may use DDI D
to drive a connector, we have to use PHY A (Combo Phy PORT A) to
detect the hotplug interrupts as per the spec because there is no
one-to-one mapping between DDIs and PHYs. Therefore, use the
function intel_port_to_phy() which contains the logic for such
mapping(s) to find the correct hpd_pin.
This change should not affect other platforms as there is always
a one-to-one mapping between DDIs and PHYs.
v2:
- Convert the case statements to use PHYs instead of PORTs (Jani)
v3:
- Refactor the function to reduce the number of return statements by
lumping all the case statements together except PHY_F which needs
special handling (Jose)
v4:
- Add a comment describing how the HPD pin value associated with any
port can be retrieved using port or phy enum value. (Jani)
v5:
- Use case ranges instead of individual labels and also normalize the
return statement by adding -PHY_A to the expression (Ville)

Currently we only set the DRM_CONNECTOR_POLL_{DISCONNECT,CONNECT}
bits in intel_connector->polled (the base setting), leading to
some confusing looking code to reset drm_connector->polled
(the actual setting) to DRM_CONNECTOR_POLL_HPD. Let's set
intel_connector->polled = DRM_CONNECTOR_POLL_HPD for all hpd
capable connectors, and then we don't need so many special
cases in the hotplug code.

enum port is a mess now because it no longer matches the spec
at all. Let's start to dig ourselves out of this hole by
reducing our reliance on port_name(). This should at least make
a bunch of debug messages a bit more sensible while we think how
to fill the the hole properly.
