The decision to use DFP output format conversion capabilities should be
during compute_config phase.
This patch adds new member to crtc_state to represent the final
output_format to the sink. In case of a DFP this can be different than
the output_format, as per the format conversion done via the PCON.
This will help to store only the format conversion capabilities of the
DP device in intel_dp->dfp, and use crtc_state to compute and store the
configuration for color/format conversion for a given mode.
v2: modified the new member to crtc_state to represent the final
output_format that eaches the sink, after possible conversion by
PCON kind of devices. (Ville)
v3: Addressed comments from Ville:
-Added comments to clarify difference between sink_format and
output_format.
-Corrected the order of setting sink_format and output_format.
-Added readout for sink_format in get_pipe_config hooks.
v4: Set sink_format for intel_sdvo too. (Ville)
v5: Rebased.
v6: Fixed condition to go for YCbCr420 format for dp and hdmi. (Ville)
v7: Fix the condition to set sink_format for HDMI.
Set hdmi output_format simply as sink_format. (Ville)

The intel_dsi_msleep() helper skips sleeping if the MIPI-sequences have
a version of 3 or newer and the panel is in vid-mode.
This is based on the big comment around line 730 which starts with
"Panel enable/disable sequences from the VBT spec.", where
the "v3 video mode seq" column does not have any wait t# entries.
Checking the Windows driver shows that it does always honor
the VBT delays independent of the version of the VBT sequences.
Commit 6fdb335f1c9c ("drm/i915/dsi: Use unconditional msleep for
the panel_on_delay when there is no reset-deassert MIPI-sequence")
switched to a direct msleep() instead of intel_dsi_msleep()
when there is no MIPI_SEQ_DEASSERT_RESET sequence, to fix
the panel on an Acer Aspire Switch 10 E SW3-016 not turning on.
And now testing on a Nextbook Ares 8A shows that panel_on_delay
must always be honored otherwise the panel will not turn on.
Instead of only always using regular msleep() for panel_on_delay
do as Windows does and always use regular msleep() everywhere
were intel_dsi_msleep() is used and drop the intel_dsi_msleep()
helper.
Changes in v2:
- Replace all intel_dsi_msleep() calls instead of just
the intel_dsi_msleep(panel_on_delay) call

On TGL+ the DSS control registers are at different offsets, and there's
one per pipe. Fix the offsets to fix dual link DSI for TGL+.
There would be helpers for this in the DSC code, but just do the quick
fix now for DSI. Long term, we should probably move all the DSS handling
into intel_vdsc.c, so exporting the helpers seems counter-productive.

Define the contents of the transcoder timing registers using
REG_GENMASK() & co. For ease of maintenance let's just define
the bitmasks with the full 16bit width (also used by the
current hand rolled stuff) even though not all bits are actually
used. None of the unsued bits have ever contained anything.
Jani spotted that the CRT load detection code did use narrower
bitmasks, so that is now going to change. But that is fine
since any garbage in the high bits would have been caught by
the state checker that always used the full 16bit masks.

Rename PIPECONF to TRANSCONF to make it clear what it actually
applies to.
While the usual convention is to pick the earliers name I think
in this case it's more clear to use the later name. Especially
as even the register offset is in the wrong range (0x70000 vs.
0x60000) and thus makes it look like this is per-pipe.
There is one place in gvt that's doing something with TRANSCONF
while iterating with for_each_pipe(). So that might not be doing
the right thing for TRANSCODER_EDP, dunno. Not knowing what it
does I left it as is to avoid breakage.

Name the CPU transcoder timing registers TRANS_FOO rather than
just FOO. This is the modern name, after the pipe/transcoder split
happened. Makes it a bit more obvious whether you pass in a pipe or
a transcoder.
PIPESRC is a bit special as it's a pipe register, even though it
lives in the transcoder registers range (0x60000 instead of 0x70000).
And BCLRPAT I suppose is a transcoder register (since it has something
to do with the timing generator), but it doesn't even exist after gen4
so I left it to use the only name it ever had in bspec.
And while at it let's pass in the correct enum in few more
places why don't we. Although in all those places the distinction

We now have some eDP+DSI dual panel systems floating around
where the DSI panel is the secondary LFP and thus needs to
consult "panel type 2" in VBT in order to locate all the
other panel type dependant stuff correctly.
To that end we need to pass in the devdata to
intel_bios_init_panel_late(), otherwise it'll just assume
we want the primary panel type. So let's try to just populate
the vbt.ports[] stuff and encoder->devdata for icl+ DSI
panels as well.
We can't do this on older platforms as there we risk a DSI
port aliasing with a HDMI/DP port, which is a totally legal

Lots of ADL machines out there with bogus VBTs that declare
two eDP child devices. In order for those to work we need to
figure out which power sequencer to use before we try the EDID
read. So let's do the panel VBT init early if we can, falling
back to the post-EDID init otherwise.
The post-EDID init panel_type=0xff approach of assuming the
power sequencer should already be enabled doesn't really work
with multiple eDP panels, and currently we just end up using
the same power sequencer for both eDP ports, which at least
confuses the wakeref tracking, and potentially also causes us
to toggle the VDD for the panel when we should not.

-> i915_reg.h. Since i915_trace.h doesn't actually need i915_irq.h,
makes sense to drop it, but that requires adding quite a few new

Prefer including i915_reg.h where needed instead of adding another
implicit include, because eventually we'll want to split up i915_reg.h

Move the panel specific VBT parsing to happen during the
output probing stage. Needs to be done because the VBT
parsing will need to look at the EDID to determine
the correct panel_type on some machines.
We split the parsed VBT data (i915->vbt) along the same
boundary. For the moment we just hoist all the panel
specific stuff into connector->panel.vbt since that seems
like the most convenient place for eg. the backlight code.
Note that we simply drop the drrs type check from
intel_drrs_frontbuffer_update() since that operates on the whole
device rather than a specific connector/encoder. But the check
was just a micro optimization so removing it doesn't actually
mattter for correctness.
TODO: Lot's of cleanup to be done in the future. Eg. most of
the DSI stuff could probably be eliminated entirely and just
parsed on demand during DSI init.
