This commit introduces the definitions for the ICL clocks and adds the
basic functions to the shared DPLL framework. It adds code for the
Enable and Disable sequences for some PLLs, but it does not have the
code to compute the actual PLL values, which are marked as TODO
comments and should be introduced as separate commits.
Special thanks to James Ausmus for investigating and fixing a bug with
the placement of icl_unmap_plls_to_ports() function.
v2:
- Rebase around dpll_lock changes.
v3:
- The spec now says what the timeouts should be.
- Touch DPCLKA_CFGCR0_ICL at the appropriate time so we don't freeze
the machine.
- Checkpatch found a white space problem.
- Small adjustments before upstreaming.
v4:
- Move the ICL checks out of the *map_plls_to_ports() functions
(James)
- Add extra encoder check (James)
- Call icl_unmap_plls_to_ports() later (James)
v5:
- Rebase after the pll struct changes.
v6:
- Properly make the unmap function based on encoders_post_disable()
with regarding to checks and iterators.
- Address checkpatch comment on "min = max = x()".

ICL has two slices of DBuf, each slice of size 1024 blocks.
We should not always enable slice-2. It should be enabled only if
display total required BW is > 12GBps OR more than 1 pipes are enabled.
Changes since V1:
- typecast total_data_rate to u64 before multiplication to solve any
possible overflow (Rodrigo)
- fix where skl_wm_get_hw_state was memsetting ddb, resulting
enabled_slices to become zero
- Fix the logic of calculating ddb_size
Changes since V2:
- If no-crtc is part of commit required_slices will have value "0",
don't try to disable DBuf slice.
Changes since V3:
- Create a generic helper to enable/disable slice
- don't return early if total_data_rate is 0, it may be cursor only
commit, or atomic modeset without any plane.
Changes since V4:
- Solve checkpatch warnings
- use kernel types u8/u64 instead of uint8_t/uint64_t
Changes since V5:
- Rebase

Interrupts other than the one for AUX errors are required only for debug,
so unmask them via debugfs when the user requests debug.
User can make such a request with
echo 1 > <DEBUG_FS>/dri/0/i915_edp_psr_debug
There are no locks to serialize PSR debug enabling from
irq_postinstall() and debugfs for simplicity. As irq_postinstall() is
called only during module initialization/resume and IGT subtests
aren't expected to modify PSR debug at those times, we should be safe.
v2: Unroll loops (Ville)
Avoid resetting error mask bits.
v3: Unmask interrupts in postinstall() if debug was still enabled.
Avoid RMW (Ville)
v4: Avoid extra IMR write introduced in the previous version.(Jose)

v11: Addressed review comments from Shashank Sharma
Alignment issues fixed.
When call to skl_update_scaler is made, 0 was being
sent instead of pixel_format.
When crtc update scaler is called, we dont have the
fb to derive the pixel format. Added the function
parameter bool plane_scaler_check to account for this.
v12: Fixed failure in IGT debugfs_test.
fb is NULL in skl_update_scaler_plane
Due to this, accessing fb->format caused failure.
Patch checks fb before using.
v13: In the previous version there was a flaw.
In skl_update_scaler during plane_scaler_check
if the format was non-NV12, it would set need_scaling
to false. This could reset the previously set need_scaling
from a previous condition check. Patch fixes this.
Patch also adds minimum src height for YUV 420 formats
to 16 (as defined in BSpec) and adds for checking this
range.
v14: Addressed review comments from Maarten
Just add a check for NV12 min src height in
skl_update_scaler and retain the remaining checks
as is. Added Reviewed By from Juha-Pekka Heikkila.
v15: Rebased the series.
v16: Changed fb height restriction to be >= 16 as per
Bspec. Earlier it was > 16.
v17: Adding src width and height to be mult of 4 restriction
to avoid pipe fifo underruns for NV12.

For YUV 420 Planar formats like NV12,
buffer allocation is done for Y and UV surfaces separately.
For NV12 plane formats, the UV buffer
allocation must be programmed in the Plane Buffer Config register
and the Y buffer allocation must be programmed in the
Plane NV12 Buffer Config register. Both register values
should be verified during verify_wm_state.

So far we are using frontbuffer tracking for everything
and ignoring that PSR has a HW capable HW tracking for many
modern usages of GPU on Core platforms and newer Atom ones.
One reason for that is that we were trying to keep same
infrastructure in place for VLV/CHV than the rest of platforms.
But also because when this infrastructure was created
the front-buffer-tracking origin wasn't that good and stable
how it is today after Paulo reworked it to attend FBC cases.
However this PSR implementation without HW tracking died
on gen8LP. And newer platforms are starting to demand more HW
tracking specially with PSR2 cases in mind.
By disabling and re-enabling PSR totally every time we believe
someone is going to change the front buffer content we don't
allow PSR HW tracking to do this job and specially compromising
the whole idea of PSR2 case where the HW tracking detect only
the damaged area and do a partial screen update.
So, from now on, on the platforms that has hw_tracking let's
rely more on HW tracking.
This also is the case in used by other drivers and more validated
by SV teams. So I hope that this will lead us to less misterious
bugs.
v2: Only do this for platform that actually has hw tracking.
v3 from DK
Do this only for flips, small gradual changes are better.

LSPCON likes to throw short HPDs during the enable seqeunce prior to the
link being trained. These obviously result in the channel CR/EQ check
failing and thus we schedule a pointless hotplug work to retrain the
link. Avoid that by ignoring the bad CR/EQ status until we've actually
initially trained the link.
I've not actually investigated to see what LSPCON is trying to signal
with the short pulse. But as long as it signals anything I think we're
supposed to check the link status anyway, so I don't really see other
good ways to solve this. I've not seen these short pulses being
generated by normal DP sinks.

Doing link retraining from the short pulse handler is problematic since
that might introduce deadlocks with MST sideband processing. Currently
we don't retrain MST links from this code, but we want to change that.
So better to move the entire thing to the hotplug work. We can utilize
the new encoder->hotplug() hook for this.
The only thing we leave in the short pulse handler is the link status
check. That one still depends on the link parameters stored under
intel_dp, so no locking around that but races should be mostly harmless
as the actual retraining code will recheck the link state if we
end up there by mistake.
v2: Rebase due to ->post_hotplug() now being just ->hotplug()
Check the connector type to figure out if we should do
the HDMI thing or the DP think for DDI

The LG 4k TV I have doesn't deassert HPD when I turn the TV off, but
when I turn it back on it will pulse the HPD line. By that time it has
forgotten everything we told it about scrambling and the clock ratio.
Hence if we want to get a picture out if it again we have to tell it
whether we're currently sending scrambled data or not. Implement
that via the encoder->hotplug() hook.

Currently we pin a fence on every plane doing tiled scanout. The
number of planes we have available is fast apporaching the number
of fences so we really should stop wasting them. Only FBC needs
the fence on gen4+, so let's use fences only for the primary planes
on those platforms.
v2: drop the tiling check from plane_uses_fence() as the obj is
NULL during initial_plane_config() and we don't rally need the
check since i915_vma_pin_fence() does the check anyway

This commit adds the basic CDCLK functions, but it's still missing
pieces of the display initialization sequence.
v2:
- Implement the voltage levels.
- Rebase.
v3:
- Adjust to the new "bypass" clock (Imre).
- Call intel_dump_cdclk_state() too.
- Rename a variable to avoid confusion.
- Simplify the DVFS part.
v4:
- Remove wrong bit definition (James).
- Also drive-by fix the coding style for the register definition we
touched.
v5:
- Comment style (checkpatch).

DP HDCP1.4 spec mandates that An can be written to panel only after
detecting the panel's hdcp capability.
For DP 0th Bit of Bcaps register indicates the panel's hdcp capability
For HDMI valid BKSV indicates the panel's hdcp capability.
For HDMI it is optional to detect the panel's hdcp capability before
An Write.
v2:
Added comments explaining the need for action [Seanpaul].
Made panel's hdcp capability detection optional for hdmi [Seanpaul].
Defined a func for reading bcaps for DP [Seanpaul].
v3:
Removed the NULL initialization [Seanpaul].

As described in the WA on GLK and CNL planes on the right edge of the
screen that have less than 4 pixels visible from the beginning of the
plane to the edge of the screen can cause FIFO underflow and display
corruption.
On GLK/CNL I could trigger the problem only if the plane was at the same
time also aligned to the top edge of the screen (after clipping) and
there were exactly 2 pixels visible from the start of the plane to the
right edge of the screen (so couldn't trigger it with 1 or 3 pixels
visible). Nevertheless, to be sure, I also applied the WA for these cases.
I also couldn't see any problem with the cursor plane and later Art
confirmed that it's not affected, so the WA is applied only for the
other plane types.
v2:
- Use -ERANGE instead of -EINVAL. (Chris)
