drm/i915: implement async_flip mode per plane tracking

Current implementation of async flip w/a relies on assumption that
previous atomic commit contains valid information if async_flip is still
enabled on the plane. It is incorrect. If previous commit did not modify
the plane its state->uapi.async_flip can be false. As a result DMAR/PIPE
errors can be observed:
i915 0000:00:02.0: [drm] *ERROR* Fault errors on pipe A: 0x00000080
i915 0000:00:02.0: [drm] *ERROR* Fault errors on pipe A: 0x00000080
DMAR: DRHD: handling fault status reg 2
DMAR: [DMA Read NO_PASID] Request device [00:02.0] fault addr 0x0 [fault reason 0x06] PTE Read access is not set

v2: update async_flip_planes in more reliable places (Ville)
v3: reset async_flip_planes and do_async_flip in more scenarios (Ville)
v4: move all resets to plane loops (Ville)

drm/i915/psr: Split sel fetch plane configuration into arm and noarm

SEL_FETCH_CTL registers are armed immediately when plane is disabled.
SEL_FETCH_* instances of plane configuration are used when doing
selective update and normal plane register instances for full updates.
Currently all SEL_FETCH_* registers are written as a part of noarm
plane configuration. If noarm and arm plane configuration are not
happening within same vblank we may end up having plane as a part of
selective update before it's PLANE_SURF register is written.

Fix this by splitting plane selective fetch configuration into arm and
noarm versions and call them accordingly. Write SEL_FETCH_CTL in arm
version.

v3:
 - add arm suffix into intel_psr2_disable_plane_sel_fetch
v2:
 - drop color_plane parameter from arm part
 - dev_priv -> i915 in arm part

drm/i915/pxp: Pxp hw init should be in resume_complete

During suspend flow, i915 currently achors' on the pm_suspend_prepare
callback as the location where we quiesce the entire GPU and perform
all necessary cleanup in order to go into suspend. PXP is also called
during this time to perform the arbitration session teardown (with
the assurance no additional GEM IOCTLs will come after that could
restart the session).

However, if other devices or drivers fail their suspend_prepare, the
system will not go into suspend and i915 will be expected to resume
operation. In this case, we need to re-initialize the PXP hardware
and this really should be done within the pm_resume_complete callback
which is the correct opposing function in the resume sequence to
match pm_suspend_prepare of the suspend sequence.

Because this callback is the last thing at the end of resuming
we expect little to no impact to the rest of the i915 resume sequence
with this change.

drm/i915/pxp: Trigger the global teardown for before suspending

A driver bug was recently discovered where the security firmware was
receiving internal HW signals indicating that session key expirations
had occurred. Architecturally, the firmware was expecting a response
from the GuC to acknowledge the event with the firmware side.
However the OS was in a suspended state and GuC had been reset.

Internal specifications actually required the driver to ensure
that all active sessions be properly cleaned up in such cases where
the system is suspended and the GuC potentially unable to respond.

This patch adds the global teardown code in i915's suspend_prepare
code path.

v2 : Split __pxp_global_teardown_locked helper into two variants
     for teardown-with-restart vs teardown-for-suspend/shutdown.

drm/i915/pxp: Invalidate all PXP fw sessions during teardown

A gap was recently discovered where if an application did not
invalidate all of the stream keys (intentionally or not), and the
driver did a full PXP global teardown on the GT subsystem, we
find that future session creation would fail on the security
firmware's side of the equation. i915 is the entity that needs
ensure the sessions' state across both iGT and security firmware
are at a known clean point when performing a full global teardown.

Architecturally speaking, i915 should inspect all active sessions
and submit the invalidate-stream-key PXP command to the security
firmware for each of them. However, for the upstream i915 driver
we only support the arbitration session that can be created
so that will be the only session we will cleanup.

drm/i915: Add _PICK_EVEN_2RANGES()

It's a constant pattern in the driver to need to use 2 ranges of MMIOs
based on port, phy, pll, etc. When that happens, instead of using
_PICK_EVEN(), _PICK() needs to be used.  Using _PICK() is discouraged
due to some reasons like:

1) It increases the code size since the array is declared
   in each call site
2) Developers need to be careful not to incur an
   out-of-bounds array access
3) Developers need to be careful that the indexes match the
   table. For that it may be that the table needs to contain
   holes, making (1) even worse.

Add a variant of _PICK_EVEN() that works with 2 ranges and selects which
one to use depending on the index value.

v2: Fix the address expansion in the example (Anusha)

drm/i915/display: add intel_display_limits.h for key enums

Move a handful of key enums to a new file intel_display_limits.h. These
are the enum types, and the MAX/NUM enumerations within them, that are
used in other headers. Otherwise, there's no common theme between them.

Replace intel_display.h include with intel_display_limit.h where
relevant, and add the intel_display.h include directly in the .c files
where needed.

Since intel_display.h is used almost everywhere in display/, include it
from intel_display_types.h to avoid massive changes across the
board. There are very few files that would need intel_display_types.h
but not intel_display.h so this is neglible, and further cleanup between
these headers can be left for the future.

Overall this change drops the direct and indirect dependencies on
intel_display.h from about 300 to about 100 compilation units, because
we can drop the include from i915_drv.h.

the hardware ELD buffer. Stop doing so.

The one slight caveat here is that this is not strictly legal
according to the HDA spec. PD=1;ELD=0 is only documented as

that depends on that then I guess we're fine. Or we could
perhaps set ELD=1 without actually programming the buffer?

Note that the bspec sequence of PD=0;ELD=0 -> PD=1;ELD=0 ->
PD=1;ELD=1 is also not strictly correct according to the HDA
spec, as the only documented transition from PD=0;ELD=0 is
straight to PD=1;ELD=1.

Additionally on hsw/bdw the hardware buffer is tied in with the
dedicated display HDA controller's power state, so currently
we mostly fail at proramming the buffer anyway. When the HDA
side is not sufficiently powered up the ELD address bits get
stuck and the ELD data register accesses go nowhere.

drm/i915/dmc: Prepare to use unversioned paths

New DMC releases in linux-firmware will stop using version number in
blob filenames. This new convention provides the following benefits:

  1. It simplifies code maintenance, as new DMC releases for a platform
     using the new convention will always use the same filename for the
     blob.

  2. It allows DMC to be loaded even if the target system does not have
     the most recent firmware installed.

Prepare the driver by:

  - Using the new convention for DMC_PATH() and renaming the currently
    used one to make it clear it is for the legacy scheme.

  - Implementing a fallback mechanism for future transitions from
    versioned to unversioned paths so that we do not cause a regression
    for systems not having the most up-to-date linux-firmware files.

v2:
  - Keep using request_firmware() instead of firmware_request_nowarn().

v3:

    so that we do not disturb initrd generation.

drm/edid: add separate drm_edid_connector_add_modes()

The original goal with drm_edid_connector_update() was to have a single
call for updating the connector and adding probed modes, in this order,
but that turned out to be problematic. Drivers that need to update the
connector in the .detect() callback would end up updating the probed
modes as well. Turns out the callback may be called so many times that
the probed mode list fills up without bounds, and this is amplified by
add_alternate_cea_modes() duplicating the CEA modes on every call,
actually running out of memory on some machines.

Kudos to Imre Deak <imre.deak@intel.com> for explaining this to me.

Go back to having separate drm_edid_connector_update() and
drm_edid_connector_add_modes() calls. The former may be called from
.detect(), .force(), or .get_modes(), but the latter only from
.get_modes().

Unlike drm_add_edid_modes(), have drm_edid_connector_add_modes() update
the probed modes from the EDID property instead of the passed in
EDID. This is mainly to enforce two things:

1) drm_edid_connector_update() must be called before
   drm_edid_connector_add_modes().

   Display info and quirks are needed for parsing the modes, and we
   don't want to call update_display_info() again to ensure the info is
   available, like drm_add_edid_modes() does.

2) The same EDID is used for both updating the connector and adding the
   probed modes.

Fortunately, the change is easy, because no driver has actually adopted
drm_edid_connector_update(). Not even i915, and that's mainly because of
the problem described above.

drm/edid: split HDMI VSDB info and mode parsing

Separate the parsing of display info and modes from the HDMI VSDB. This
is prerequisite work for overall better separation of the two parsing
steps.

The info parsing is about figuring out whether the sink supports HDMI
infoframes. Since they were added in HDMI 1.4, assume the sink supports
HDMI infoframes if it has the HDMI_Video_present bit set (introduced in
HDMI 1.4). For details, see commit f1781e9bb2dd ("drm/edid: Allow HDMI
infoframe without VIC or S3D").

The logic is not exactly the same, but since it was somewhat heuristic
to begin with, assume this is close enough.

v2:
- Simplify to only check HDMI_Video_present bit (Ville)
- Drop cea_db_raw_size() helper (Ville)

drm: exynos: dsi: Fix MIPI_DSI*_NO_* mode flags

HFP/HBP/HSA/EOT_PACKET modes in Exynos DSI host specifies
0 = Enable and 1 = Disable.

The logic for checking these mode flags was correct before

This patch is trying to fix this MIPI_DSI*_NO_* mode flags handling
Exynos DSI host and update the mode_flags in relevant panel drivers.
