Display features should not be initialized or de-initialized when there
is no display. Skip modeset initialization, output setup, plane, crtc,
encoder, connector registration, display cdclk and rawclk
initialization, display core initialization, etc.
Skip the functionality at as high level as possible, and remove any
redundant checks. If the functionality is conditional to *other* display
checks, do not add more. If the un-initialization has checks for
initialization, do not add more.
We explicitly do not care about any GMCH/VLV/CHV code paths, as they've
always had and will have display.

Add a small wrapper for .hpd_irq_setup() which does the
"do we even have the hook?" and "are display interrupts enabled?"
checks.

Currently we call .hpd_irq_setup() directly just before display
resume, and follow it with another call via intel_hpd_init()
just afterwards. Assuming the hpd pins are marked as enabled
during the open-coded call these two things do exactly the
same thing (ie. enable HPD interrupts). Which even makes sense
since we definitely need working HPD interrupts for MST sideband
during the display resume.
So let's nuke the open-coded call and move the intel_hpd_init()
call earlier. However we need to leave the poll_init_work stuff
behind after the display resume as that will trigger display
detection while we're resuming. We don't want that trampling over
the display resume process. To make this a bit more symmetric
we turn this into a intel_hpd_poll_{enable,disable}() pair.
So we end up with the following transformation:
intel_hpd_poll_init() -> intel_hpd_poll_enable()
lone intel_hpd_init() -> intel_hpd_init()+intel_hpd_poll_disable()
.hpd_irq_setup()+resume+intel_hpd_init() -> intel_hpd_init()+resume+intel_hpd_poll_disable()
If we really would like to prevent all *long* HPD processing during
display resume we'd need some kind of software mechanism to simply
ignore all long HPDs. Currently we appear to have that just for
fbdev via ifbdev->hpd_suspended. Since we aren't exploding left and
right all the time I guess that's mostly sufficient.
For a bit of history on this, we first got a mechanism to block
hotplug processing during suspend in commit 15239099d7a7 ("drm/i915:
enable irqs earlier when resuming") on account of moving the irq enable
earlier. This then got removed in commit 50c3dc970a09 ("drm/fb-helper:
Fix hpd vs. initial config races") because the fdev initial config
got pushed to a later point. The second ad-hoc hpd_irq_setup() for
resume was added in commit 0e32b39ceed6 ("drm/i915: add DP 1.2 MST
support (v0.7)") to be able to do MST sideband during the resume.
And finally we got a partial resurrection of the hpd blocking
mechanism in commit e8a8fedd57fd ("drm/i915: Block fbdev HPD
processing during suspend"), but this time it only prevent fbdev
from handling hpd while resuming.
v2: Leave the poll_init_work behind

Make a clean split between hpd pins for DDI vs. TC. This matches
how the actual hardware is split.
And with this we move the DDI/PHY->HPD pin mapping into the encoder
init instead of having to remap yet again in the interrupt code.

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.

HPD pin handling for RKL+TGP is a special case; we effectively select

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)

Everything about the file is about display, and mostly about types
related to display. Move under display/ as intel_display_types.h to
reflect the facts.
There's still plenty to clean up, but start off with moving the file
where it logically belongs and naming according to contents.
v2: fix the include guard name in the renamed file

Add hotdplug detection for all ports on TGP. icp_hpd_detection_setup()
is refactored to be shared with TGP.
While we increase the number of pins, add a BUILD_BUG_ON() to avoid
going over the number of bits allowed.
v2: use BITS_PER_TYPE and correct type for BUILD_BUG_ON() check

There is some scenarios that we are aware that sink probe can fail,
so lets add the infrastructure to let hotplug() hook to request
another probe after some time.
v2: Handle shared HPD pins (Imre)
v3: Rebased
v4: Renamed INTEL_HOTPLUG_NOCHANGE to INTEL_HOTPLUG_UNCHANGED to keep
it consistent(Rodrigo)
v5: Making the working queue used explicit through all the callers to
hotplug_work (Ville)

Now that we have a new subdirectory for display code, continue by moving
modesetting core code.
display/intel_frontbuffer.h sticks out like a sore thumb, otherwise this
is, again, a surprisingly clean operation.
v2:
- don't move intel_sideband.[ch] (Ville)
- use tabs for Makefile file lists and sort them
