79708d142e drm/i915/sdvo: Reduce copy-pasta in output setup
Avoid having to call the output init function for each
output type separately. We can just call the right one
based on the "class" of the output.

Technically we could just walk the bits of the bitmask
but that could change the order in which we initialize
the outputs. To avoid any behavioural changes keep to
the same explicit probe order as before.

5e52622efb drm/i915/sdvo: Don't add DDC modes for LVDS
Stop enumerating the DDC modes for SDVO LVDS outputs (outside
the initial fixed mode setup). intel_panel_mode_valid() will
just reject most of them anyway, and any left over are entirely
pointless as they'll match the fixed mode hdisp+vdisp+vrefresh
so no user visible effect from using them instead of the fixed

64b7b557dc drm/i915/sdvo: Setup DDC fully before output init
Call intel_sdvo_select_ddc_bus() before initializing any
of the outputs. And before that is functional (assuming no VBT)
we have to set up the controlled_outputs thing. Otherwise DDC
won't be functional during the output init but LVDS really
needs it for the fixed mode setup.

Note that the whole multi output support still looks very
bogus, and more work will be needed to make it correct.
But for now this should at least fix the LVDS EDID fixed mode
setup.

c3c5dc1d92 drm/i915/audio: Do the vblank waits
The spec tells us to do a bunch of vblank waits in the audio
enable/disable sequences. Make it so.

The FIXMEs are nonsense since we do the audio disable very
early and enable very late, so vblank interrupts are in fact
enabled when we do this.

TODO not sure we actually want these since we don't even rely
on the hw ELD buffer, and these might be there just to give
the audio side a bit of time to respond to the unsol events.
OTOH they might be really needed for some other reason.

cbbda2ffbb drm/i915/audio: Split "ELD valid" vs. audio PD on hsw+
On the older platforms the audio presence detect bit is in
the port register, so it gets written outside audio codec hooks
and is this separate from the ELD valid toggling. Split the
operations into two steps on hsw+ to be more consistent with
both the other platforms and the spec. Also according to the
spec we might need some vblank waits between the two which
definitely needs them done separately.

7c8d74e813 drm/i915/audio: Use intel_de_rmw() for most audio registers
The audio code does a lot of RMW accesses. Utilize

There are still some hand rolled RMW left, but those have

0234cda2ce drm/i915/audio: Make sure we write the whole ELD buffer
Currently we only write as many dwords into the hardware
ELD buffers as drm_eld_size() tells us. That could mean the
remainder of the hardware buffer is left with whatever
stale garbage it had before, which doesn't seem entirely
great. Let's zero out the remainder of the buffer in case
the provided ELD doesn't fill it fully.

We can also sanity check out idea of the hardware ELD buffer's
size by making sure the address wrapped back to zero once
we wrote the entire buffer.

9f4a51256f drm/i915/audio: Protect singleton register with a lock
On the "ilk" platforms AUD_CNTL_ST2 is a singleton. Protect
it with the audio mutex in case we ever want to do parallel
RMW access to it.

Currently that should not happen since we only do audio
enable/disable from full modesets, and those are fully
serialized. But we probably want to think about toggling
audio on/off from fastsets too.

The hsw codepaths already have the same locking.
g4x should not need it since it can only do audio to a
single port at a time, which means it's actually broken
in more ways than this atm.

b8ed55335e drm/i915/tgl+: Sanitize DKL PHY register definitions
Not all Dekel PHY registers have a lane instance, so having to specify
this when using them is awkward. It makes more sense to define each PHY
register with its full internal PHY offset where bits 15:12 is the lane
for lane-instanced PHY registers and just a register bank index for other
PHY registers. This way lane-instanced registers can be referred to with
the (tc_port, lane) parameters, while other registers just with a tc_port
parameter.

An additional benefit of this change is to prevent passing a Dekel
register to a generic MMIO access function or vice versa.

v2:
- Fix parameter	reuse in the DKL_REG_MMIO definition.
v3:
- Rebase on latest patchset version.

89cb0ba4ce drm/i915/tgl+: Add locking around DKL PHY register accesses
Accessing the TypeC DKL PHY registers during modeset-commit,
-verification, DP link-retraining and AUX power well toggling is racy
due to these code paths being concurrent and the PHY register bank
selection register (HIP_INDEX_REG) being shared between PHY instances
(aka TC ports) and the bank selection being not atomic wrt. the actual
PHY register access.

Add the required locking around each PHY register bank selection->
register access sequence.

Kudos to Ville for noticing the race conditions.

v2:
- Add the DKL PHY register accessors to intel_dkl_phy.[ch]. (Jani)
- Make the DKL_REG_TC_PORT macro independent of PHY internals.
- Move initing the DKL PHY lock to a more logical place.

v3:
- Fix parameter reuse in the DKL_REG_TC_PORT definition.
- Document the usage of phy_lock.

v4:
- Fix adding TC_PORT_1 offset in the DKL_REG_TC_PORT definition.

794aca0ec2 drm/edid: use struct drm_edid for override/firmware EDID
There's a lot going on here, but the main thing is switching the
firmware EDID loader to use struct drm_edid. Unfortunately, it's
difficult to reasonably split to smaller pieces.

Convert the EDID loader to struct drm_edid. There's a functional change
in validation; it no longer tries to fix errors or filter invalid
blocks. It's stricter in this sense. Hopefully this will not be an
issue.

As a by-product, this change also allows HF-EEODB extended EDIDs to be
passed via override/firmware EDID.

90b575f52c drm/edid: detach debugfs EDID override from EDID property update
Having the EDID override debugfs directly update the EDID property is
problematic. The update is partial only. The driver has no way of
knowing it's been updated. Mode list is not updated. It's an
inconsistent state.

Detach debugfs EDID override from the property update completely. Only
set and reset a separate override EDID copy from debugfs, and have it
take effect only at detect (via EDID read). The copy is at
connector->edid_override, protected by connector->edid_override_mutex.

This also brings override EDID closer to firmware EDID in behaviour.

Add validation of the override EDID which we completely lacked.

Note that IGT already forces a detect whenever tests update the override
EDID.

6e0fff462e drm/i915/hdmi: do dual mode detect only if connected
For normal connector detect, there's really no point in trying dual mode
detect if the connector is disconnected. We can simplify the detect
sequence by skipping it. Since intel_hdmi_dp_dual_mode_detect() is only
called when EDID is present, we can drop the has_edid parameter.

The functional effect is speeding up disconnected connector detection
ever so slightly, and, combined with firmware EDID, also stop logging
about assuming dual mode adaptor.

It's a bit subtle, but this will also skip dual mode detect if the
connector is force connected and a) there's no EDID of any kind, normal
or override/firmware or b) there's EDID but it does not indicate
digital. These are corner cases no matter what, and arguably forcing
should not be limited by dual mode detect.
