We're going to want access to the atomic state for iterating
the slave crtcs when enabling the port sync master crtc. Pass
the atomic state all the way down.
The alternative would be yet another encoder hook which we'll
have to call after all the normal modeset stuff is done. Not
really a fan of yet another hook just for this.
Note that during readout state sanitation we are now going
to pass NULL as the atomic state since we don't have one.
We need to change that and then we can also s/crtc_state/crtc/
and s/conn_state/conn/ for the encoder hooks as well.

Transcoder port sync was introduced to the hardware in BDW. We
can trivially enable it for SKL+ since the same codepaths are
already used for ICL+ port sync. The only difference is the actual
location of the bits we need to poke.
We leave BDW out (at least for now) since it uses different modeset
paths that haven't been adapted for port sync, and IIRC using the
feature would involve some extra workarounds we've not implemented.
Pre-BDW hardware does not support port sync so we'd have to tweak
the modeset sequence to start the pipes as close together as possible
and hope for the best. So far no one has seriously tried to implement
that.

Few edp panels like Sharp is triggering short and long
hpd pulse after panel is getting powered off.
Currently driver is already ignoring long pulse for eDP
panel but in order to process the short pulse, it turns on
the VDD which requires panel power_cycle_delay + panel_power_on_delay
these delay on Sharp panel introduced the responsiveness overhead
of 800ms in the modeset sequence and as well is in suspend
sequence.
Ignoring any short pulse if panel is powered off.
FIXME: It requires to wait for panel_power_off delay in order
to check the panel power status due to pps_lock because panel triggers
short pulse immediately after writing PP_OFF to PP_CTRL register and
wait_panel_off waits for panel_power_off delay with pps_lock held.
This still creates responsiveness overhead of panel_power_off delay.
v2:
- checking vdd along with panel power to ignore the hpd. [Jani,Ville]
v3:
- safer side check to ignore the long hpd when eDP have power,
adding type of hpd to debug log. [Jani]

In order to support state readout for DP VSC SDP, we need to have a
structure which holds DP VSC SDP payload data such as
"union hdmi_infoframe drm" which is used for DRM infoframe.
It adds a struct drm_dp_vsc_sdp vsc to intel_crtc_state.infoframes.
And it stores computed dp vsc sdp to infoframes.vsc of crtc state.
While computing we'll also fill out the inforames.enable bitmask
appropriately.
The compute routine follows DP 1.4 spec [Table 2-117: VSC SDP Payload for

This fixes a problem found on the MacBookPro 2017 Retina panel.
The panel reports 10 bpc color depth in its EDID, and the
firmware chooses link settings at boot which support enough
bandwidth for 10 bpc (324000 kbit/sec = multiplier 0xc),
but the DP_MAX_LINK_RATE dpcd register only reports
2.7 Gbps (multiplier value 0xa) as possible, in direct
contradiction of what the firmware successfully set up.
This restricts the panel to 8 bpc, not providing the full
color depth of the panel.
This patch adds a quirk specific to the MBP 2017 15" Retina
panel to add the additiional 324000 kbps link rate during
edp setup.
Link to previous discussion of a different attempted fix
with Ville and Jani:
https://patchwork.kernel.org/patch/11325935/
v2: Follow Jani's proposal of defining quirk_rates[] instead
of just appending 324000. This for better clarity.
v3: Rebased onto current drm-tip, as of 16-March-2020. Adapt
to new edid_quirks parameter of drm_dp_has_quirk().

The whole point of using OUIs is so that we can recognize certain
devices and potentially apply quirks for them. Normally this should work
quite well, but there appears to be quite a number of laptop panels out
there that will fill the OUI but not the device ID. As such, for devices
like this I can't imagine it's a very good idea to try relying on OUIs
for applying quirks. As well, some laptop vendors have confirmed to us
that their panels have this exact issue.
So, let's introduce the ability to apply DP quirks based on EDID
identification. We reuse the same quirk bits for OUI-based quirks, so
that callers can simply check all possible quirks using
drm_dp_has_quirk().

Some devices with a builtin panel have the panel mounted upside down,
this is indicated by the rotate_180 bit in the BDB_GENERAL_FEATURES VBT
block.
We store this info in dev_priv->vbt.orientation, use this to set the
connector's orientation property so that fbcon and userspace will show
the image the right way up on devices with an upside-down mounted panel.
This fixes the image being upside-down on a Teclast X89 tablet.

consistent is a good thing anyway. Also some of this might get
cleaned up a bit more later as we keep propagating the intel_

Not every platform needs quirk detection for panel orientation, so
split the drm_connector_init_panel_orientation_property into two
functions. One for platforms without the need for quirks, and the
other for platforms that need quirks.
Hans de Goede (changes in v2):
Rename the function from drm_connector_init_panel_orientation_property
to drm_connector_set_panel_orientation[_with_quirk] and pass in the
panel-orientation to set.
Beside the rename, also make the function set the passed in value
only once, if the value was set before (to a value other then
DRM_MODE_PANEL_ORIENTATION_UNKNOWN) make any further set calls a no-op.
This change is preparation for allowing the user to override the
panel-orientation for any connector from the kernel commandline.
When the panel-orientation is overridden this way, then we must ignore
the panel-orientation detection done by the driver.
