In general, prefer struct drm_i915_private * over struct drm_device *
when either will do. Rename the local variable to i915. Also propagate
to intel_hpd_poll_fini(). No functional changes.

When audio power domain is suspended, the display driver must
save state of AUD_FREQ_CNTRL on Tiger Lake and Ice Lake
systems. The initial value of the register is set by BIOS and
is read by driver during the audio component init sequence.

Gamma lut programming can be programmed using DSB
where bulk register programming can be done using indexed
register write which takes number of data and the mmio offset
to be written.
Currently enabled for 12-bit gamma LUT which is enabled by
default and later 8-bit/10-bit will be enabled in future
based on need.

v2: Directly call dsb-api at callsites. (Jani)
v3:
- modified the code as per single dsb instance per crtc. (Shashank)
- Added dsb get/put call in platform specific load_lut hook. (Jani)
- removed dsb pointer from dev_priv. (Jani)
v4: simplified code by dropping ref-count implementation. (Shashank)

This patch adds a function, which will internally get the gem buffer
for DSB engine. The GEM buffer is from global GTT, and is mapped into
CPU domain, contains the data + opcode to be feed to DSB engine.
v1: Initial version.
v2:
- removed some unwanted code. (Chris)
- Used i915_gem_object_create_internal instead of _shmem. (Chris)
- cmd_buf_tail removed and can be derived through vma object. (Chris)
v3: vma realeased if i915_gem_object_pin_map() failed. (Shashank)
v4: for simplification and based on current usage added single dsb
object in intel_crtc. (Shashank)
v5: seting NULL to cmd_buf moved outside of mutex in dsb-put(). (Shashank)
v6:
- refcount machanism added.
- Used atomic_add_return and atomic_dec_and_test instead of
atomic_inc and atomic_dec. (Jani)

For icl+, have hw read out to create hw blob of gamma
lut values. icl+ platforms supports multi segmented gamma
mode by default, add hw lut creation for this mode.
This will be used to validate gamma programming using dsb
(display state buffer) which is a tgl specific feature.
Major change done-removal of readouts of coarse and fine segments
because PAL_PREC_DATA register isn't giving propoer values.
State checker limited only to "fine segment"
v2: -readout code for multisegmented gamma has to come
up with some intermediate entries that aren't preserved
in hardware (Jani N)
-linear interpolation (Ville)
-moved common code to check gamma_enable to specific funcs,
since icl doesn't support that
v3: -use u16 instead of __u16 [Jani N]
-used single lut [Jani N]
-improved and more readable for loops [Jani N]
-read values directly to actual locations and then fill gaps [Jani N]
-moved cleaning to patch 1 [Jani N]
-renamed icl_read_lut_multi_seg() to icl_read_lut_multi_segment to
make it similar to icl_load_luts()
-renamed icl_compute_interpolated_gamma_blob() to
icl_compute_interpolated_gamma_lut_values() more sensible, I guess
v4: -removed interpolated func for creating gamma lut values
-removed readouts of fine and coarse segments, failure to read PAL_PREC_DATA
correctly

On ILK-IVB the pipe colorspace is configured via PIPECONF
(as opposed to PIPEMISC in BDW+). Let's configure+readout
that stuff correctly.
Enabling YCbCr 4:4:4 output will now be a simple matter of
setting crtc_state->output_format appropriately in the encoder
.compute_config(). However, when we do that we must be
aware of the fact that YCbCr DP output doesn't seem to work
on ILK (resulting image is totally garbled), but on SNB+
it works fine. However HDMI YCbCr output does work correctly
even on ILK.

Prepare the pipe csc for YCbCr output on ilk/snb. The main difference
to IVB+ is the lack of explicit post offsets, and instead we must
configure the CSC info RGB->YUV mode (which takes care of offsetting
Cb/Cr properly) and enable the "black screen offset" bit to add the
required offset to Y.
And while at it throw some comments around the bit defines to
document which platforms have which bits.

Make intel_get_crtc_ycbcr_config() simpler and rename it

it does.
Also toss in some comments to document that the 4:2:0 PIPECONF

Since HSW the PIPECONF progressive vs. interlaced selection is done
with just two bits instead of the earlier three. Let's not look at the
extra bit on HSW+. Also gen2 doesn't support interlaced displays at all.
This is actually fine as is currently because the extra bit is mbz (as
are all three bits on gen2). But just to avoid mishaps in the future
if the bits get reused let's only look at what's properly defined.

crtc_state->limited_color_range only applies to RGB output but
we're currently setting it even for YCbCr output. That will
lead to conflicting MSA and PIPECONF settings which can mess
up the image. Let's make sure limited_color_range stays unset
with YCbCr output.
Also WARN if we end up with such a bogus combination when
programming the MSA MISC bits as it's impossible to even
indicate quantization rangle for YCbCr via MSA MISC. YCbCr
output is simply assumed to be limited range always. Note
that VSC SDP does provide a mechanism for full range YCbCr,
so in the future we may want to rethink how we compute/store
this state.
And for good measure we add the same WARN to the HDMI path.

Looks like we're currently setting the MSA to xvYCC BT.709 instead
of the YCbCr BT.601 claimed by the comment. But even that comment
is wrong since we configure the CSC matrix to BT.709.
Let's remove the bogus statement from the comment and fix the
MSA to indicate YCbCr BT.709 so that it matches the actual
pixel data we're transmitting.

before it is completed). Upon retiring the request, the context may be
unpinned and freed, and along with it the timeline may be freed. We
therefore need to be very careful when chasing rq->timeline that the
pointer does not disappear beneath us. The vast majority of users are in
a protected context, either during request construction or retirement,
where the timeline->mutex is held and the timeline cannot disappear. It
is those few off the beaten path (where we access a second timeline) that
need extra scrutiny -- to be added in the next patch after first adding
the warnings about dangerous access.
One complication, where we cannot use the timeline->mutex itself, is
during request submission onto hardware (under spinlocks). Here, we want
to check on the timeline to finalize the breadcrumb, and so we need to
impose a second rule to ensure that the request->timeline is indeed
valid. As we are submitting the request, it's context and timeline must
be pinned, as it will be used by the hardware. Since it is pinned, we
know the request->timeline must still be valid, and we cannot submit the
idle barrier until after we release the engine->active.lock, ergo while
submitting and holding that spinlock, a second thread cannot release the
timeline.
v2: Don't be lazy inside selftests; hold the timeline->mutex for as long
as we need it, and tidy up acquiring the timeline with a bit of
refactoring (i915_active_add_request)

Modern platforms allow the transcoders hdisplay/vdisplay to exceed the
planes' max resolution. This has the nasty implication that modes on the
connectors' mode list may not be usable when the user asks for a
fullscreen plane. Seeing as that is the most common use case it seems
prudent to filter out modes that don't allow for fullscreen planes to
be enabled.
Let's do that in the connetor .mode_valid() hook so that normally
such modes are kept hidden but the user is still able to forcibly
specify such a mode if they know they don't need fullscreen planes.
This is in line with ealier policies regarding certain clock limits.
The idea is to prevent the casual user from encountering a mode that
would fail under typical conditions, but allow the expert user to
force things if they so wish.
Maybe in the future we should consider automagically using two
planes when one can't cover the entire screen? Wouldn't be a
great match for the current uapi with explicit planes though,
but I guess no worse than using two pipes (which we apparently
have to in the future anyway). Either that or we'd have to
teach userspace to do it for us.

The officially validated plane width limit is 4k on skl+, however
we already had people using 5k displays before we started to enforce
the limit. Also it seems Windows allows 5k resolutions as well
(though not sure if they do it with one plane or two).
According to hw folks 5k should work with the possible
exception of the following features:
- Ytile (already limited to 4k)
- FP16 (already limited to 4k)
- render compression (already limited to 4k)
- KVMR sprite and cursor (don't care)
- horizontal panning (need to verify this)
- pipe and plane scaling (need to verify this)
So apart from last two items on that list we are already
fine. We should really verify what happens with those last
two items but I don't have a 5k display on hand atm so it'll
have to wait.
In the meantime let's just bump the limit back up to 5k since
several users have already been using it without apparent issues.
At least we'll be no worse off than we were prior to lowering
the limits.

We generally assume future platforms will inherit the behavior of the
most recent platforms, so update our DDC pin mapping defaults to match
how ICP/TGP behave (i.e., pins starting from GMBUS_PIN_1_BXT for combo
PHY's and pins starting from GMBUS_PIN_9_TC1_ICP for TC PHY's). MCC's
non-standard handling of combo PHY C seems like a platform-specific
quirk that is unlikely to be duplicated on future platforms, so continue
handling it as a special case.
Without this change, future platforms would default to gen4-style pin
mapping which is almost certainly not what we'll want.

Stop setting ->pipe_mask to zero when display is disabled, allowing us
to have different code paths for not actually having display hardware,
and having display hardware disabled. This lets us develop those two
avenues independently.
There are no functional changes for when there is no display. However,
all uses of for_each_pipe() and for_each_pipe_masked() will start
running for the disabled display case. Put one of the more significant
ones behind checks for INTEL_DISPLAY_ENABLED(), otherwise the cases
should not be hit with disabled display, or they seem benign. Fingers
crossed.
All in all, this might not be the ideal solution. In fact we may have
had something along the lines of this in the past, but we ended up
conflating the two cases. Possibly even by recommendation by yours
truly; I did not dare dig up that part of the history. But the perfect
is the enemy of the good, this is a straightforward change, and lets us
get actual work done in both fronts without interfering with each other.

Prepare for making a distinction between not having display and having
disabled display. Add INTEL_DISPLAY_ENABLED() and use it where
HAS_DISPLAY() is used after intel_device_info_runtime_init(). This is
initially duplication, as disabling display still leads to ->pipe_mask =
0 and HAS_DISPLAY() being false.
Note that ever since i915.display_disable was introduced, it has not
affected PCH detection even if it uses HAS_DISPLAY(), as display disable
happens after that.
Since INTEL_DISPLAY_ENABLED() will not make sense unless HAS_DISPLAY()
is true, include a warning for catching misuses making decisions on
INTEL_DISPLAY_ENABLED() when HAS_DISPLAY() is false.

We're forgetting to mask off all three pipe select bits from the
CDCLK_CTL value on icl+ which may lead to the extra bit being
left in. That will cause us to consider the current hardware
cdclk state as invalid, and we proceed to sanitize it even
though the hardware may have active pipes and whatnot.
Fix up the mask so we get rid of all three pipe select bits
and thus hopefully no longer sanitize cdclk when it's already
correctly programmed.

The BXT and CNL functions were already basically identical, whereas
ICL's function tried to do its own sanitization rather than calling
bxt_sanitize_cdclk.
This should actually fix a bug in our ICL initialization where it would
consider the /2 CD2X divider invalid and force an unnecessary
sanitization (we now have valid clock frequencies that use this
divider).

With all of the cdclk function consolidation, we can cut down on a lot
of platform if/else logic by creating a vfunc that's initialized at
startup.

The uninitialize flow is the same on all of these platforms, aside from
calculating a different frequency level.
v2: Reverse platform conditional order for consistency. (Ville)

The CNL variant of this function is identical to the BXT variant aside
from not needing to handle SSA precharge.

We'd previously combined ICL/TGL logic into the cnl_set_cdclk function,
but BXT is pretty similar as well. Roll the cnl/icl/tgl logic back into
the bxt function; the only things we really need to handle separately
are punit notification and calling different functions to enable/disable
the cdclk PLL.

The bspec lays out legal cdclk frequencies, PLL ratios, and CD2X
dividers in an easy-to-read table for most recent platforms. We've been
translating the data from that table into platform-specific code logic,
but it's easy to overlook an area we need to update when adding new
cdclk values or enabling new platforms. Let's just add a form of the
bspec table to the code and then adjust our functions to pull what they
need directly out of the table.
v2: Fix comparison when finding best cdclk.
v3: Another logic fix for calc_cdclk.
v4:
- Use named initializers for cdclk tables. (Ville)
- Include refclk as a field in the table instead of adding all three
ratios for each entry. (Ville)
- Terminate tables with an empty entry to avoid needing to store the
table size. (Ville)
- Don't try so hard to return reasonable values from our lookup
functions if we get impossible inputs; just WARN and return 0.
(Ville)
- Keep a bxt_ prefix on the lookup functions since they're still only
used on bxt+ for now. We can rename them later if we extend this
table-based approach back to older platforms. (Ville)
v5:
- Fix cnl table's ratios for 24mhz refclk. (Ville)
- Don't miss the named initializers on the cnl table. (Ville)
- Represent refclk in table as u16 rather than u32. (Ville)
