Ville Syrjälä bf473cb531 drm/i915: Fix cursor src/dst rectangle with bigjoiner
We can't call drm_plane_state_src() this late for the slave plane since
it would consult the wrong uapi state. We've alreayd done the correct
uapi->hw copy earlier, so let's just preserve the unclipped src/dst

Ville Syrjälä 8246d9c7ea drm/i915: Get the uapi state from the correct plane when bigjoiner is used
When using bigjoiner userspace is only controlling the "master"
plane, so use its uapi state for the "slave" plane as well.

hw.crtc needs a bit of magic since we don't want to copy that from
the uapi state (as it points to the wrong pipe for the "slave
" plane). Instead we pass the right crtc in explicitly but only
assign it when the uapi state indicates the plane to be logically
enabled (ie. uapi.crtc != NULL).

Manasi Navare 4e3cdb4535 drm/i915/dp: Master/Slave enable/disable sequence for bigjoiner
Enabling is done in a special sequence and so should plane updates
be. Ideally the end user never notices the second pipe is used.

This way ideally everything will be tear free, and updates are
really atomic as userspace expects it.

This uses generic modeset_enables() calls like trans port sync
but still has special handling for disable since for slave we
should not disable things like encoder, plls that are not enabled
for  slave.

Bob Paauwe b896898c73 drm/i915: Tweaked Wa_14010685332 for PCHs used on gen11 platforms
The WA specifies that we need to toggle a SDE chicken bit on and then
off as the final step in preparation for s0ix entry.

    Bspec: 33450
    Bspec: 8402

However, something is happening after we toggle the bit that causes
the WA to be invalidated. This makes dispcnlunit1_cp_xosc_clkreq
active being already in s0ix state i.e SLP_S0 counter incremented.
Tweaking the Wa_14010685332 by setting the bit on suspend and clearing
it on resume turns down the dispcnlunit1_cp_xosc_clkreq.
B.Spec has Documented this tweaked sequence of WA as an alternative.
Let keep this tweaked WA for Gen11 platforms and keep untweaked WA for
other platforms which never observed this issue.

v2 (MattR):
 - Change the comment on the workaround to give PCH names rather than
   platform names.  Although the bspec is setup to list workarounds by
   platform, the hardware team has confirmed that the actual issue being
   worked around here is something that was introduced back in the
   Cannon Lake PCH and carried forward to subsequent PCH's.
 - Extend the untweaked version of the workaround to include  PCH_CNP as
   well.  Note that since PCH_CNP is used to represent CMP, this will
   apply on CML and some variants of RKL too.
 - Cap the untweaked version of the workaround so that it won't apply to
   "fake" PCH's (i.e., DG1).  The issue we're working around really is
   an issue in the PCH itself, not the South Display, so it shouldn't
   apply when there isn't a real PCH.

v3:
 - use intel_de_rmw(). [Rodrigo]

Ville Syrjälä 2ca5a7b85b drm/i915: Handle max_bpc==16
EDID can declare the maximum supported bpc up to 16,
and apparently there are displays that do so. Currently
we assume 12 bpc is tha max. Fix the assumption and
toss in a MISSING_CASE() for any other value we don't
expect to see.

This fixes modesets with a display with EDID max bpc > 12.
Previously any modeset would just silently fail on platforms
that didn't otherwise limit this via the max_bpc property.
In particular we don't add the max_bpc property to HDMI
ports on gmch platforms, and thus we would see the raw
max_bpc coming from the EDID.

I suppose we could already adjust this to also allow 16bpc,
but seeing as no current platform supports that there is
little point.

Ville Syrjälä dbf71381d7 drm/i915: Nuke intel_atomic_crtc_state_for_each_plane_state() from skl+ wm code
intel_atomic_crtc_state_for_each_plane_state() peeks at the
plane's current state without holding the plane's mutex, trusting
that the crtc's mutex will protect it. In practice that does work
since our planes can't move between pipes, but it sets a bad
example. intel_atomic_crtc_state_for_each_plane_state() also
relies on crtc_state.uapi.plane_mask which may be full of lies
when it comes to the bigjoiner stuff, so soon we can't use it as
is anyway. So best to just get rid of it entirely. Which we can
easily do by switching to the g4x/vlv "raw" watermark approach.

Later on we should even be able to move the "raw" watermark
computation into the normal .plane_check() code, leaving only
the merging/clamping of the final watermarks to the later
stages. But that will require adjusting the ilk+ wm code
similarly as well.

Lucas De Marchi 11ffe97247 drm/i915/dg1: map/unmap pll clocks
DG1 uses 2 registers for the ddi clock mapping, with PHY A and B using
DPCLKA_CFGCR0 and PHY C and D using DPCLKA1_CFGCR0. Hide this behind a
single macro that chooses the correct register according to the phy
being accessed, use the correct bitfields for each pll/phy and implement
separate functions for DG1 since it doesn't share much with ICL/TGL
anymore.

The previous values were correct for PHY A and B since they were using
the same register as before and the bitfields were matching.

previous ones
