7e732cacb1 drm/i915: Stop frobbing with DDI encoder->type
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.

v2: Fix BXT/GLK PPS explosion with DSI/MST encoders
v3: Avoid the PPS warn on pure HDMI/DVI DDI encoders by checking dp.output_reg
v4: Rebase
v5: Populate output_types in .get_config() rather than in the caller
v5: Split out populating output_types in .get_config() (Maarten)

e1214b95ed drm/i915: Populate output_types from .get_config()
Rather than having the caller of .get_config() set output_types based on
encoder->type, let's just have .get_config() itself populate
output_types. This way we are isolated from encoder->type, which won't
be useable for this purpose anyway soon (at least for DDI encoders).

Starting from version 204 VBT can specify the max TMDS clock we are

be33be5df2 drm/i915: Clean up the mess around hdmi_12bpc_possible()
Move the crtc state related 12bpc checks into hdmi_12bpc_possible()
since that one already examines other parts of the crtc state.

Note that we can drop the !force_dvi check since
crtc_state->has_hdmi_sink already accounts for that.

1d7765380f drm/i915: Remove mostly duplicated video DIP handling from PSR code
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.

v2: Rebase due to other PSR changes

5f88a9c619 drm/i915: Constify states passed to enable/disable/etc. encoder hooks
The enable/disable/etc. encoder hooks aren't supposed to alter the

const thingy, so this can't catch all abuses. But at least it acts as a
hint to the reader telling them not to mess about with the state(s).

cec3bb013a drm/i915: Split pin mapping into per platform functions
Cleanup the code. Map the pins in accordance to
individual platforms rather than according to ports.
Create separate functions for platforms.

v2:
 - Add missing condition for CoffeeLake. Make platform
 specific functions static. Add function
 i915_ddc_pin_mapping().

v3:
 - Rename functions to x_port_to_ddc_pin() which directly
   indicates the purpose. Correct default return values on CNP
   and BXT. Rename i915_port_to_ to g4x_port_to since that was
   the first platform to run this. Correct code style. (Paulo)

The only special case is nouveau which used one function for both

What is rather strange here is how few drivers set this up, I suspect
the earlier patch to handle properties in the core did end up fixing a
pile of possible issues.

60436fd4d2 drm/i915: add config function for YCBCR420 outputs
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

0c1f528cb1 drm: handle HDMI 2.0 VICs in AVI info-frames
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.

v3: Add missing else and fix register table since CNP GPIO_CTL
    starts on 0xC5014.

7a5ca19f8b drm/i915: Convert intel_hdmi connector properties to atomic
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.

1595363788 drm/i915: enable scrambling
Geminilake platform sports a native HDMI 2.0 controller, and is
capable of driving pixel-clocks upto 594Mhz. HDMI 2.0 spec
mendates scrambling for these higher clocks, for reduced RF footprint.

This patch checks if the monitor supports scrambling, and if required,
enables it during the modeset.

V2: Addressed review comments from Ville:
 - Do not track scrambling status in DRM layer, track somewhere in
   driver like in intel_crtc_state.
 - Don't talk to monitor at such a low layer, set monitor scrambling
   in intel_enable_ddi() before enabling the port.

V3: Addressed review comments from Jani
 - In comments, function names, use "sink" instead of "monitor",
   so that the implementation could be close to the language of
   HDMI spec.

V4: Addressed review comment from Maarten
 - scrambling -> hdmi_scrambling
 - high_tmds_clock_ratio -> hdmi_high_tmds_clock_ratio

V5: Addressed review comments from Ville and Ander
 - Do not modifiy the crtc_state after compute_config. Move all
   scrambling and tmds_clock_ratio calcutations to compute_config.
 - While setting scrambling for source/sink, do not check the
   conditions again, just go by the crtc_state flags. This will
   simplyfy the condition checks.

V6: Addressed review comments from Ville
 - Do not add IS_GLK check in disable/enable function, instead add it
   in compute_config, while setting state flags.
 - Remove unnecessary paranthesis.
 - Simplyfy handle_sink_scrambling function as suggested.
 - Add readout code for scrambling status in get_ddi_config and add a
   check for the same in pipe_config_compare.

V7: Addressed review comments from Ander/Ville
 - No separate function for source scrambling, make it inline
 - Align the last line of the macro TRANS_DDI_HDMI_SCRAMBLING_MASK
 - Do not add platform check while setting source scrambling
 - Use pipe_config instead of crtc->config to set sink scrambling
 - To readout scrambling status, Compare with SCRAMBLING_MASK
   not any of its bits
 - Remove platform check in intel_pipe_config_compare while checking
   scrambling status

V8: Fixed mege conflict, Addressed review comments from Ander
 - Remove the desciption/comment about scrambling fom the caller, move
   it to the function
 - Move the IS_GLK check into scrambling function
 - Fix alignment

V9: Fixed review comments from Ville, Ander
 - Pass the scrambling state variables as bool input to the sink_scrambling
   function and let the disable call be unconditional.
 - Fix alignments in function calls and debug messages.
 - Add kernel doc for function intel_hdmi_handle_sink_scrambling

This should not actually never happen since it's mandatory for HDMI
sinks to support 12bpc if they support any deep color modes. But
reality disagrees with the theory and there are actually sinks in
the wild that violate the spec.

Pull drm updates from Dave Airlie:
 "This is the main drm pull request for v4.11.

  Nothing too major, the tinydrm and mmu-less support should make
  writing smaller drivers easier for some of the simpler platforms, and
  there are a bunch of documentation updates.

  Intel grew displayport MST audio support which is hopefully useful to
  people, and FBC is on by default for GEN9+ (so people know where to
  look for regressions). AMDGPU has a lot of fixes that would like new
  firmware files installed for some GPUs.

  Other than that it's pretty scattered all over.

779c4c2866 drm/edid: Set AVI infoframe Q even when QS=0
HDMI 2.0 recommends that we set the Q bits in the AVI infoframe
even when the sink does not support quantization range selection (QS=0).
According to CEA-861 we can do that as long as the Q we send matches
the default quantization range for the mode.

Previously I think I had misread the spec as saying that you can't
send a non-zero Q at all when QS=0. But that's not what the spec
actually says.

v2: Fix typo in commit message (Jani)

Pull the logic to populate the quantization range information
in the AVI infoframe into a small helper. We'll be adding a bit
more logic to it, and having it in a central place seems like a
good idea since it's based on the CEA-861 spec.

Geminilake is mostly backwards compatible with broxton, so change most

v3: Rebase

v4: Include the check intel_bios_is_port_hpd_inverted().

bbf35e9def drm/i915: Pass atomic state to intel_audio_codec_enable, v2.
drm_select_eld requires mode_config.mutex and connection_mutex
because it looks at the connector list and at the legacy encoders.

This is not required, because when we call audio_codec_enable we know
which connector it was called for, so pass the state.

This also removes having to look at crtc->config.

e4ab73a132 drm/i915: Respect alternate_ddc_pin for all DDI ports
The VBT provides the platform a way to mix and match the DDI ports vs.
GMBUS pins. Currently we only trust the VBT for DDI E, which I suppose
has no standard GMBUS pin assignment. However, there are machines out
there that use a non-standard mapping for the other ports as well.
Let's start trusting the VBT on this one for all ports on DDI platforms.

I've structured the code such that other platforms could easily start
using this as well, by simply filling in the ddi_port_info. IIRC there
may be CHV system that might actually need this.

v2: Include a commit message, include a debug message during init
