a6e7a006f5 drm/i915: Change bigjoiner state tracking to use the pipe bitmask
Get rid of the inflexible bigjoiner_linked_crtc pointer thing
and just track things as a bitmask of pipes instead. We can
also nuke the bigjoiner_slave boolean as the role of the pipe
can be determined from its position in the bitmask.

It might be possible to nuke the bigjoiner boolean as well
if we make encoder.compute_config() do the bitmask assignment
directly for the master pipe. But for now I left that alone so
that encoer.compute_config() will just flag the state as needing
bigjoiner, and the intel_atomic_check_bigjoiner() is still
responsible for determining the bitmask. But that may have to change
as the encoder may be in the best position to determine how
exactly we should populate the bitmask.

Most places that just looked at the single bigjoiner_linked_crtc
now iterate over the whole bitmask, eliminating the singular
slave pipe assumption.

f461ea5d8d drm/i915: Convert for_each_intel_crtc_mask() to take a pipe mask instead
Often using pipes is more convenient than crtc indices.
Convert the current for_each_intel_crtc_mask() to take a
pipe mask instead of a crtc index mask, and rename it to
for_each_intel_crtc_in_pipe_mask() to make it clear what
it does.

The current users of for_each_intel_crtc_mask() don't really
care which kind of mask we use, but for other uses a pipe
mask if better.

f3b603de2f drm/i915: Move the IPS code to its own file
IPS is a pretty well isolated feature. Move the relevant code
to a separate file from polluting intel_display.c.

I stuck to the hsw_ips name since that's what the function were
already using, and also to avoid confusion with the ILK
"Intelligen Power Sharing"/intel_ips GPU turbo stuff.

And let's also do the s/dev_priv/i915/ rename while touching
most of the code.

1d06c820b2 drm/i915: Clear DP M2/N2 when not doing DRRS
Make life simpler by always programming DP M2/N2 with a consistent
value. This will lets use do state readout+chec unconditionally.

I was first going to just set M2/N2=M1/N1 but then it occurred
to me that it might interfere with fastboot on account of BIOS
likely leaving the registers zeroed. So let's zero out the values
instead (except TU where a zero register value actually means '1').
Still not sure that's the best approach but lets go with it for
now.

be0c94ee21 drm/i915: Split intel_cpu_transcoder_set_m_n() into M1/N1 vs. M2/N2 variants
Make things a bit more explicit by splitting
intel_cpu_transcoder_set_m_n() into separate variants for M1/N1 vs.
M2/N2. Makes the DRRS M/N programming at least more obvious.

Note that for the MST and DRRS cases we don't need to call the
M2/N2 variant at all since the transcoders that support those
do not have the M2/N2 registers.

Same could be said for i9xx_crtc_enable() but I want to do a
higher level code sharing between that valleyview_crtc_enable()
later in which case we do need the M2/N2 variant. This is also
why I keep the transcoder_has_m2_n2() in intel_cpu_transcoder_set_m2_n2()
so the caller doesn't have necessarily care what the chosen
transcoder supports.

6678916dfa drm/i915: Move pipe/transcoder/abox masks under intel_device_info.display
Collect the dipslay related mask under the display sub-structure
in intel_device_info.

Note that there is a slight change in behaviour in that we zero
out .display entirely when !HAS_DISPLAY (aka. pipe_mask==0), so
now we also zero out the other masks (although cpu_transocder_mask
should already be zero of pipe_mask is zero). abox_mask is
only used by the display core init when HAS_DISPLAY is true, so
the actual behaviour of the system shouldn't change despite the
zeroing of these masks.

There is a lot more display stuff directly in device info that
could be moved over. Maybe someone else will be inspired to do it...

aa0813b1ba drm/i915/pps: move pps (panel) modeset asserts to intel_pps.c
Move assert_panel_unlocked() to intel_pps.c and rename
assert_pps_unlocked(). Keep the functionality and the assert code
together.

There's still a bit of a split between the eDP PPS usage in intel_pps.c
and all the other PPS usage, and assert_pps_unlocked() is arguably more
related to the latter. However, intel_pps.c is the best fit for anything
touching the PPS registers.

64851a32c4 drm/i915/tc: Add a mode for the TypeC PHY's disconnected state
A follow-up change will start to disconnect/re-connect PHYs around AUX
transfers and modeset enable/disables. To prepare for that add a new
TypeC PHY disconnected mode, to help tracking the TC-cold blocking power
domain status (no power domain in disconnected state, mode dependent
power domain in connected state).

v2: Move the !disconnected mode and phy-owned asserts in
    __intel_tc_port_lock() later in the patchset, when the asserts will
    hold. (Jose)

8c66081b0b drm/i915: s/pipe/transcoder/ when dealing with PIPECONF/TRANSCONF
PIPECONF becamse TRANSCONF when HSW introduced the EDP transcoder.
Bigjoiner is making life even more confusing by introducing
a N:1 relationship between pipes and transcoders. In that case
we only enable/configure the transcoder corresponding to the
master pipe. Let's do some renames to make it clear we're dealing
with the transcoder rather than pipe when it comes to
PIPECONF/TRANSCONF.

I decided to leave the _cpu_ part out from the function/macro
names since the PCH transcoder related stuff already has a
_pch_ in their name. So shouldn't be possible to confuse them.

fdc0b946a9 drm/i915/dg2: Classify DG2 PHY types
Although the bspec labels four of DG2's outputs as "combo PHY," the
underlying PHYs in both cases are actually Synopsys PHYs that are
programmed completely differently than the traditional Intel "combo" PHY
units.  As such, we don't want intel_phy_is_combo to take us down legacy
programming paths, so just return false from it on DG2.  Instead add a
new intel_phy_is_snps() that will return true for all DG2 PHYs.

ed2615a855 drm/i915/xelpd: Handle new location of outputs D and E
The DDI naming template for display version 12 went A-C, TC1-TC6.  With
XE_LPD, that naming scheme for DDI's has now changed to A-E, TC1-TC4.

The XE_LPD design keeps the register offsets and bitfields relating to
the TC outputs in the same location they were previously.  The new "D"
and "E" outputs now take the locations that were previously used by TC5
and TC6 outputs, or what we would have considered to be outputs "H" and
"I" under the legacy lettering scheme.

For the most part everything will just work as long as we initialize the
output with the proper 'enum port' value.  However we do need to take
care to pick the correct AUX channel when parsing the VBT (e.g., a
reference to 'AUX D' is actually asking us to use the 8th aux channel,
not the fourth).  We should also make sure that our encoders and aux
channels are named appropriately so that it's easier to correlate driver
debug messages with the bspec instructions.

v2:
 - Update handling of TGL_TRANS_CLK_SEL_PORT.  (Jose)

v3:
 - Add hpd_pin to handle outputs D and E (Jose)
 - Fixed conversion of BIOS port to aux ch for TC ports (Jose)

33e7a97510 drm/i915/xelpd: First stab at DPT support
Add support for DPT (display page table). DPT is a
slightly peculiar two level page table scheme used for
tiled scanout buffers (linear uses direct ggtt mapping
still). The plane surface address will point at a page
in the DPT which holds the PTEs for 512 actual pages.
Thus we require 1/512 of the ggttt address space
compared to a direct ggtt mapping.

We create a new DPT address space for each framebuffer and
track two vmas (one for the DPT, another for the ggtt).

TODO:
- Is the i915_address_space approaach sane?
- Maybe don't map the whole DPT to write the PTEs?
- Deal with remapping/rotation? Need to create a
  separate DPT for each remapped/rotated plane I
  guess. Or else we'd need to make the per-fb DPT
  large enough to support potentially several
  remapped/rotated vmas. How large should that be?

e7c46e43bd drm/i915: Nuke display error state
I doubt anyone has used the display error state since CS flips
went the way of the dodo. Just nuke it.

It might be semi interesting to have something like this for
FIFO underruns and the like, but as it stands this wouldn't
provide a sufficient amount of information. So would need
an extensive rewrite anyway.

The lockless power well handling is also racy, so this could
just be contributing noise to test results if we end up
accessing something with the relevant power well already
disabled.
