The HDMI helpers were implemented in the EDID and connector code, but
are actually unrelated. With the move to the display-helper library, we
can remove the dependency on drm_edid.{c,h} in some driver's HDMI source
files.
Several of the HDMI helpers remain in EDID code because both share parts
of their implementation internally. With better refractoring of the EDID
code, those HDMI helpers could be moved into the display-helper library
as well.

The current code assumes that the RGB444 and YUV444 formats are the
same, but the HDMI 2.0 specification states that:
The three DC_XXbit bits above only indicate support for RGB 4:4:4 at
that pixel size. Support for YCBCR 4:4:4 in Deep Color modes is
indicated with the DC_Y444 bit. If DC_Y444 is set, then YCBCR 4:4:4
is supported for all modes indicated by the DC_XXbit flags.
So if we have YUV444 support and any DC_XXbit flag set but the DC_Y444
flag isn't, we'll assume that we support that deep colour mode for
YUV444 which breaks the specification.
In order to fix this, let's split the edid_hdmi_dc_modes field in struct
drm_display_info into two fields, one for RGB444 and one for YUV444.

Currently we just use all the hdmi_deep_color_possible() stuff
to compute whether deep color is possible, and leave the 8bpc
case to do its own thing. That doesn't mesh super well with 4:2:0
handling because we might end up going for 8bpc RGB without
considering that it's essentially illegal and we could instead
go for a legal 4:2:0 config.
So let's run through all the clock checks even for 8bpc first.
If we've fully exhausted all options only then do we re-run
the computation for 8bpc while ignoring the downstream TMDS
clock limits. This will guarantee that if there's a config
that respects all limits we will find it, and if there is not
we still allow the user to override the mode manually.

Lots of machines these days seem to have a crappy type1 DP dual
mode adaptor chip slapped onto the motherboard. Based on the
DP dual mode spec we currently limit those to 165MHz max TMDS
clock.
Windows OTOH ignores DP dual mode adaptors when the VBT
indicates that the port is not actually DP++, so we can
perhaps assume that the vendors did intend that the 165MHz
clock limit doesn't apply here. Though it would be much
nicer if they actually declared an explicit limit through
VBT, but that doesn't seem to be happening either.
So in order to match Windows behaviour let's ignore the
DP dual mode adaptor's TMDS clock limit for ports that
don't look like DP++ in VBT.
Unfortunately many older VBTs misdelcare their DP++ ports
as just HDMI (eg. ILK Dell Latitude E5410) or DP (eg. SNB
Lenovo ThinkPad X220). So we can't really do this universally
without risking black screens. I suppose a sensible cutoff
is HSW+ since that's when 4k became a thing and one might
assume that the machines have been tested to work with higher
TMDS clock rates.

Looks like our VBIOS/GOP generally fail to turn the DP dual mode adater
TMDS output buffers back on after a reboot. This leads to a black screen
after reboot if we turned the TMDS output buffers off prior to reboot.
And if i915 decides to do a fastboot the black screen will persist even
after i915 takes over.
Apparently this has been a problem ever since commit b2ccb822d3 ("drm/i915:
Enable/disable TMDS output buffers in DP++ adaptor as needed") if one
rebooted while the display was turned off. And things became worse with
commit fe0f1e3bfd ("drm/i915: Shut down displays gracefully on reboot")
since now we always turn the display off before a reboot.
This was reported on a RKL, but I confirmed the same behaviour on my
SNB as well. So looks pretty universal.
Let's fix this by explicitly turning the TMDS output buffers back on
in the encoder->shutdown() hook. Note that this gets called after irqs
have been disabled, so the i2c communication with the DP dual mode
adapter has to be performed via polling (which the gmbus code is
perfectly happy to do for us).
We also need a bit of care in handling DDI encoders which may or may
not be set up for HDMI output. Specifically ddc_pin will not be
populated for a DP only DDI encoder, in which case we don't want to
call intel_gmbus_get_adapter(). We can handle that by simply doing
the dual mode adapter type check before calling
intel_gmbus_get_adapter().

When encoder validation of a display mode fails, retry with less bandwidth
heavy YCbCr420 color mode, if available. This enables some HDMI 1.4 setups
to support 4k60Hz output, which previously failed silently.
AMDGPU had nearly the exact same issue. This problem description is
therefore copied from my commit message of the AMDGPU patch.
On some setups, while the monitor and the gpu support display modes with
pixel clocks of up to 600MHz, the link encoder might not. This prevents
YCbCr444 and RGB encoding for 4k60Hz, but YCbCr420 encoding might still be
possible. However, which color mode is used is decided before the link
encoder capabilities are checked. This patch fixes the problem by retrying
to find a display mode with YCbCr420 enforced and using it, if it is
valid.

Since we're about to be using drm_dbg_*() throughout the DP helpers, we'll
need to be able to access the DRM device in the dual mode DP helpers as
well. Note however that since drm_dp_dual_mode_detect() can be called with
DDC adapters that aren't part of a drm_dp_aux struct, we need to pass down
the drm_device to these functions instead of using drm_dp_aux.

While converting the rest of the driver to use GRAPHICS_VER() and
MEDIA_VER(), following what was done for display, some discussions went
back on what we did for display:
1) Why is the == comparison special that deserves a separate
macro instead of just getting the version and comparing directly
like is done for >, >=, <=?
2) IS_DISPLAY_RANGE() is weird in that it omits the "_VER" for
brevity. If we remove the current users of IS_DISPLAY_VER(), we
could actually repurpose it for a range check
With (1) there could be an advantage if we used gen_mask since multiple
conditionals be combined by the compiler in a single and instruction and
check the result. However a) INTEL_GEN() doesn't use the mask since it
would make the code bigger everywhere else and b) in the cases it made
sense, it also made sense to convert to the _RANGE() variant.
So here we repurpose IS_DISPLAY_VER() to work with a [ from, to ] range
like was the IS_DISPLAY_RANGE() and convert the current IS_DISPLAY_VER()
users to use == and != operators. Aside from the definition changes,
this was done by the following semantic patch:
@@ expression dev_priv, E1; @@
- !IS_DISPLAY_VER(dev_priv, E1)

The SDVO/HDMI port register limited color range bit can only be used
with TMDS encoding and not SDVO encoding, ie. to be used only when
using the port as a HDMI port as opposed to a SDVO port. The SDVO
spec does have a note that some GMCHs might allow that, but gen4
bspec vehemently disagrees. I suppose on ILK+ it might work since
the color range handling is on the CPU side rather than on the PCH
side, so there is no clear linkage between the TMDS vs. SDVO
encoding and color range. Alas, I have no hardware to test that
theory.
To implement limited color range support for SDVO->HDMI we need to
ask the SDVO device to do the range compression. Do so, but first
check if the device even supports the colorimetry selection.

Fix skl_update_scaler_crtc() to deal with different scaling
modes correctly. The current implementation assumes
DRM_MODE_SCALE_FULLSCREEN. Fortunately we don't expose any
border properties currently so the code does actually end
up doing the right thing (assigning a scaler for pfit).
The code does need to be fixed before any borders are
exposed.
Also we have redundant calls to skl_update_scaler_crtc() in
dp/hdmi .compute_config() which can be nuked. They were anyway
called before we had even computed the pfit state so were
basically nonsense. The real call we need to keep is in
intel_crtc_atomic_check().

The alternative would be yet another encoder hook which we'll

Note that during readout state sanitation we are now going

For the HPD interrupt functionality the HW depends on power wells in the
display core domain to be on. Accordingly when enabling these power
wells the HPD polling logic will force an HPD detection cycle to account
for hotplug events that may have happened when such a power well was
off.
Thus a detect cycle started by polling could start a new detect cycle if
a power well in the display core domain gets enabled during detect and
stays enabled after detect completes. That in turn can lead to a
detection cycle runaway.
To prevent re-triggering a poll-detect cycle make sure we drop all power
references we acquired during detect synchronously by the end of detect.
This will let the poll-detect logic continue with polling (matching the
off state of the corresponding power wells) instead of scheduling a new
detection cycle.

crtc_state->limited_color_range only applies to RGB output but
we're currently setting it even for YCbCr output. That will
lead to conflicting MSA and PIPECONF settings which can mess
up the image. Let's make sure limited_color_range stays unset
with YCbCr output.
Also WARN if we end up with such a bogus combination when
programming the MSA MISC bits as it's impossible to even
indicate quantization rangle for YCbCr via MSA MISC. YCbCr
output is simply assumed to be limited range always. Note
that VSC SDP does provide a mechanism for full range YCbCr,
so in the future we may want to rethink how we compute/store
this state.
And for good measure we add the same WARN to the HDMI path.

Modern platforms allow the transcoders hdisplay/vdisplay to exceed the
planes' max resolution. This has the nasty implication that modes on the
connectors' mode list may not be usable when the user asks for a
fullscreen plane. Seeing as that is the most common use case it seems
prudent to filter out modes that don't allow for fullscreen planes to
be enabled.
Let's do that in the connetor .mode_valid() hook so that normally
such modes are kept hidden but the user is still able to forcibly
specify such a mode if they know they don't need fullscreen planes.
This is in line with ealier policies regarding certain clock limits.
The idea is to prevent the casual user from encountering a mode that
would fail under typical conditions, but allow the expert user to
force things if they so wish.
Maybe in the future we should consider automagically using two
planes when one can't cover the entire screen? Wouldn't be a
great match for the current uapi with explicit planes though,
but I guess no worse than using two pipes (which we apparently
have to in the future anyway). Either that or we'd have to
teach userspace to do it for us.

We generally assume future platforms will inherit the behavior of the
most recent platforms, so update our DDC pin mapping defaults to match
how ICP/TGP behave (i.e., pins starting from GMBUS_PIN_1_BXT for combo
PHY's and pins starting from GMBUS_PIN_9_TC1_ICP for TC PHY's). MCC's
non-standard handling of combo PHY C seems like a platform-specific
quirk that is unlikely to be duplicated on future platforms, so continue
handling it as a special case.
Without this change, future platforms would default to gen4-style pin
mapping which is almost certainly not what we'll want.

Reogranize the HDMI deep color state computation to just
loop over possible bpc values. Avoids having to maintain
so many variants of the clock etc.
The current code also looks confused w.r.t. port_clock vs.
bw_constrained. It would happily update port_clock for
deep color but then not actually enable deep color due to
bw_constrained being set. The new logic handles that case
correctly.

Right now we are aware of two cases that needs another hotplug retry:
- Unpowered type-c dongles
- HDMI slow unplug
Both have a complete explanation in the code to schedule another run
of the hotplug handler.
It could have more checks to just trigger the retry in those two
specific cases but why would sink signal a long pulse if there is
no change? Also the drawback of running the hotplug handler again
is really low and that could fix another cases that we are not
aware.
Also retrying for old DP ports(non-DDI) to make it consistent and not
cause CI failures if those systems are connected to chamelium boards
that will be used to simulate the issues reported in here.
