When we're disabling the HDMI link we try to reset the scrambling and
TMDS bit clock ratio back to the default values. This will fail if the
sink has already been disconnected. Thus we should not print an error
message when resetting the scrambling/TMDS bit clock ratio fail during
disable. During enable we do want the error, and during disable we may
still want to know what happended for debug purposes so let's use
DRM_DEBUG_KMS() there.

The LG 4k TV I have doesn't deassert HPD when I turn the TV off, but
when I turn it back on it will pulse the HPD line. By that time it has
forgotten everything we told it about scrambling and the clock ratio.
Hence if we want to get a picture out if it again we have to tell it
whether we're currently sending scrambled data or not. Implement
that via the encoder->hotplug() hook.

We never support certain mode flags etc. Reject those early on in the
mode_config.mode_valid() hook. That allows us to remove some duplicated
checks from the connector .mode_valid() hooks, and it guarantees that
we never see those flags even from user mode as the
mode_config.mode_valid() hooks gets executed for those as well.

4K modes testing by using dummy EDID data has never been working
properly on boxes with DP++ (dual-mode) adaptors. The reason for
this is that those modes got pruned during hdmi mode validation.
intel_hdmi_mode_valid returns CLOCK_HIGH because the pixel clock
reported by the 4k mode is higher than dual port TMDS clock limit.
However 4k injection does work properly on machines that don't have
DP++ adapters because the mode is never validated against the DP++
TMDS clock limit.
v2: Don't detect the DP++ limits when we're testing using overridden
EDIDs. Make sure to check for the override condition after
respecting the value of drm_dp_dual_mode_detect (Jani Nikula).

The ACK/NACK implementation as found in e.g. the G965 has the falling
clock edge and the release of the data line after the ACK for the received
byte happen at the same time.
This is conformant with the I2C specification, which allows a zero hold
time, see footnote [3]: "A device must internally provide a hold time of
at least 300 ns for the SDA signal (with respect to the V IH(min) of the
SCL signal) to bridge the undefined region of the falling edge of SCL."
Some HDMI-to-VGA converters apparently fail to adhere to this requirement
and latch SDA at the falling clock edge, so instead of an ACK
sometimes a NACK is read and the slave (i.e. the EDID ROM) ends the
transfer.
The bitbanging releases the data line for the ACK only 1/4 bit time after
the falling clock edge, so a slave will see the correct value no matter
if it samples at the rising or the falling clock edge or in the center.
Fallback to bitbanging is already done for the CRT connector.

drm/edid: Don't send non-zero YQ in AVI infoframe for HDMI 1.x sinks
drm/vc4: Account for interrupts in flight
Appedix F of HDMI 2.0 says that some HDMI sink may fail to switch from
3D to 2D mode in a timely fashion if the source simply stops sending the
HDMI infoframe. The suggested workaround is to keep sending the
infoframe even when strictly not necessary (ie. no VIC and no S3D).
HDMI 1.4 does allow for this behaviour, stating that sending the
infoframe is optional in this case.
The infoframe was first specified in HDMI 1.4, so in theory sinks
predating that may not appreciate us sending an uknown infoframe
their way. To avoid regressions let's try to determine if the sink
supports the infoframe or not. Unfortunately there's no direct way
to do that, so instead we'll just check if we managed to parse any
HDMI 1.4 4k or stereo modes from the EDID, and if so we assume the
sink will accept the infoframe. Also if the EDID contains the HDMI
2.0 HDMI Forum VSDB we can assume the sink is prepared to receive
the infoframe.
v2: Fix getting has_hdmi_infoframe from display_info

Apparently some sinks look at the YQ bits even when receiving RGB,
and they get somehow confused when they see a non-zero YQ value.
So we can't just blindly follow CEA-861-F and set YQ to match the
RGB range.
Unfortunately there is no good way to tell whether the sink
designer claims to have read CEA-861-F. The CEA extension block
revision number has generally been stuck at 3 since forever,
and even a very recently manufactured sink might be based on
an old design so the manufacturing date doesn't seem like
something we can use. In lieu of better information let's
follow CEA-861-F only for HDMI 2.0 sinks, since HDMI 2.0 is
based on CEA-861-F. For HDMI 1.x sinks we'll always set YQ=0.
The alternative would of course be to always set YQ=0. And if
we ever encounter a HDMI 2.0+ sink with this bug that's what
we'll probably have to do.

Explicitly pass the crtc and connector states into the audio

This gets rid of almost all crtc->config and encoder->crtc
uses. The one place where we still use them is
i915_audio_component_sync_audio_rate() since that gets called from
the audio driver and we don't have explicit states around then.

Currently the DDI encoder->type will change at runtime depending on
what kind of hotplugs we've processed. That's quite bad since we can't
really trust that that current value of encoder->type actually matches
the type of signal we're trying to drive through it.
Let's eliminate that problem by declaring that non-eDP DDI port will
always have the encoder type as INTEL_OUTPUT_DDI. This means the code
can no longer try to distinguish DP vs. HDMI based on encoder->type.
We'll leave eDP as INTEL_OUTPUT_EDP, since it'll never change and
there's a bunch of code that relies on that value to identify eDP
encoders.
We'll introduce a new encoder .compute_output_type() hook. This allows
us to compute the full output_types before any encoder .compute_config()
hooks get called, thus those hooks can rely on output_types being
correct, which is useful for cloning on oldr platforms. For now we'll
just look at the connector type and pick the correct mode based on that.
In the future the new hook could be used to implement dynamic switching
between LS and PCON modes for LSPCON.

Now that the infoframe hooks are part of the intel_dig_port, we can use
the normal .write_infoframe() hook to update the VSC SDP. We do need to
deal with the size difference between the VSC DIP and the others though.
Another minor snag is that the compiler will complain to use if we keep
using enum hdmi_infoframe_type type and passing in the DP define instead,
so et's just change to unsigned int all over for the inforframe type.

To get a YCBCR420 output from intel platforms, we need one
scaler to scale down YCBCR444 samples to YCBCR420 samples.
This patch:
- Does scaler allocation for HDMI ycbcr420 outputs.
- Programs PIPE_MISC register for ycbcr420 output.
V2: rebase
V3: rebase
V4: rebase
V5: addressed review comments from Ander:
- No need to check both scaler_user && hdmi_output.
Check for scaler_user is enough.
V6: rebase
V7: Do not create a new scaler user, use existing pipe scaler user.
V8: rebase
V9: Addressed review comments from Ville:
- Remove leftover comment for HDMI scaler user.
- Remove unnecessary blank line.
- Make scaler alocation failure a DEBUG log instead of ERROR.

This patch checks encoder level support for YCBCR420 outputs.
The logic goes as simple as this:
If the input mode is YCBCR420-only mode: prepare HDMI for
YCBCR420 output, else continue with RGB output mode.
It checks if the mode is YCBCR420 and source can support this
output then it marks the ycbcr_420 output indicator into crtc
state, for further staging in driver.
V2: Split the patch into two, kept helper functions in DRM layer.
V3: Changed the compute_config function based on new DRM API.
V4: Rebase
V5: Rebase
V6: Check and handle YCBCR420-only modes, discard the property
based approach (Ville)
V7: Addressed review comments from Ville
- add else case in 12BPC check.
- extract ycbcr420 state inside hdmi_12bpc_possible function.
V8: Addressed review comments from Ville
- Remove extra blank lines.
- Remove "HDMI" from the description of ycbcr420 state variable.
- Remove local variable, use crtc_state->ycbcr420 instead.

HDMI 1.4b support the CEA video modes as per range of CEA-861-D (VIC 1-64).
For any other mode, the VIC filed in AVI infoframes should be 0.
HDMI 2.0 sinks, support video modes range as per CEA-861-F spec, which is
extended to (VIC 1-107).
This patch adds a bool input variable, which indicates if the connected
sink is a HDMI 2.0 sink or not. This will make sure that we don't pass a
HDMI 2.0 VIC to a HDMI 1.4 sink.
This patch touches all drm drivers, who are callers of this function
drm_hdmi_avi_infoframe_from_display_mode but to make sure there is
no change in current behavior, is_hdmi2 is kept as false.
In case of I915 driver, this patch:
- checks if the connected display is HDMI 2.0.
- HDMI infoframes carry one of this two type of information:
- VIC for 4K modes for HDMI 1.4 sinks
- S3D information for S3D modes
As CEA-861-F has already defined VICs for 4K videomodes, this
patch doesn't allow sending HDMI infoframes for HDMI 2.0 sinks,
until the mode is 3D.

On CNP PCH based platforms the gmbus is on the south display that
is on PCH. The existing implementation for previous platforms
already covers the need for CNP expect for the pin pair configuration
that follows similar definitions that we had on BXT.
v2: Don't drop "_BXT" as the indicator of the first platform
supporting this pin numbers. Suggested by Daniel.
v3: Add missing else and fix register table since CNP GPIO_CTL
starts on 0xC5014.
v4: Fix pin number and map according to the current available VBT.
Re-add pin 4 for port D. Lost during some rebase.
v5: Use table as spec. If VBT is wrong it should be ignored.

intel_hdmi supports 3 properties, force_audio, broadcast rgb and
scaling mode. The last one is only created for eDP, so the is_eDP
in set_property is not required.
panel fitting and broadcast rgb are straightforward and only requires
changing compute_config.
force_audio is also used to force DVI mode, which means changes to
compute_config and mode_valid. mode_valid is called with
connection_mutex held, so it can safely dereference connector->state.
