When any other value than EDP_PSR_TP4_TIME_0US is set, TPS1 and TPS4
will be used to do the link training when exiting PSR1.
Happily the eDP panels tested so far was able to sync with source
even without HBR3/TPS4 support but let use the right training
pattern.
TPS4 support was added to PSR1 registers because HBR3/PSR
specification was not closed when ICL was freezed so if HBR3 was
supported by PSR, ICL would already be ready but it was not added to
specification so lets always disable TPS4.

As there are no upstream drivers for VED or ISP let's just

prevent s0ix entry.
For ISP this is only relevant when it is not exposed as a
PCI device and instead is a subordinate of the gunit. When
exposed as a PCI device it will be handled by the
atomisp2_pm driver.
On my VLV FFRD8 board the firmware power gates both of these
by default. Let's assume that is always the case and just

Fix the TODO leftover in the code by changing the argument in MG_PLL
macros. The MG_PLL ids used to access the register values can be
converted from tc_port rather than port.
All these registers can use the TC port to calculate the right offsets
because they are only available for TC ports. The range (PORT_C onwards)
may not be stable and change from platform to platform. So by using the
TC id directly we avoid having to check for the platform in the "leaf
functions" and thus passing dev_priv around.
The helper functions were also renamed to use "tc" as prefix to make
them more generic.

To make vblank timestamps work better with the TV encoder let's
scale the pipe timings such that the relationship between the
TV active and TV blanking periods is mirrored in the
corresponding pipe timings.
Note that in reality the pipe runs at a faster speed during the
TV vblank, and correspondigly there are periods when the pipe
is enitrely stopped. We pretend that this isn't the case and
as such we incur some error in the vblank timestamps during
the TV vblank. Further explanation of the issues in a big
comment in the code.
This makes the vblank timestamps good enough to make
i965gm (which doesn't have a working frame counter with
the TV encoder) report correct frame numbers. Previously
you could get all kinds of nonsense which resulted in
eg. glxgears reporting that it's running at twice the
actual framerate in most cases.

SFC (Scaler & Format Converter) units are shared between VD and VEBoxes.
They also happen to have separate reset bits. So, whenever we want to reset
one or more of the media engines, we have to make sure the SFCs do not
change owner in the process and, if this owner happens to be one of the
engines being reset, we need to reset the SFC as well.
This happens in 4 steps:
1) Tell the engine that a software reset is going to happen. The engine
will then try to force lock the SFC (if currently locked, it will
remain so; if currently unlocked, it will ignore this and all new lock
requests).
2) Poll the ack bit to make sure the hardware has received the forced
lock from the driver. Once this bit is set, it indicates SFC status
(lock or unlock) will not change anymore (until we tell the engine it
is safe to unlock again).
3) Check the usage bit to see if the SFC has ended up being locked to
the engine we want to reset. If this is the case, we have to reset
the SFC as well.
4) Unlock all the SFCs once the reset sequence is completed.
Obviously, if we are resetting the whole GPU, we don't have to worry
about all of this.

bits).
While at it also check for the correctness of GEN, port, transcoder. I
wasn't sure if psr2_enabled can only be set for GEN9+, but that seems to
be the case indeed (see setting of sink_psr2_support in
intel_psr_init_dpcd()).
v2 (Ville):
- Make gen9_chicken_trans_reg() internal to intel_psr.c.
- s/trans/cpu_transcoder/

Depending on the transcoder enum values to translate from transcoder
to EDP PSR flags can easily break if we add a new transcoder. So remove
the dependency by using an explicit mapping.
While at it also add a WARN for unexpected trancoders.
v2:
- Simplify things by defining flag shift values instead of indices.
- s/trans/cpu_transcoder/ (Ville)
v3:
- Define flags to look like separate bits instead of the values of
the same bitfield. (Ville)

This got duplicated on introducing icl workarounds.
Fix by using the older definition and moving the wa bit
definition there. No functional changes.
v3: avoid fixes tag, whitespace (Chris)

Although CNP names this field "Counter Fraction", what we write to the
register is really the denominator for the fractional part of the
divider, not the fractional part (and the field description even says
that). The ICP spec renamed the field to "Counter Fraction
Denominator", which makes a lot more sense. Use the more complete ICL
naming because we will merge the CNP and ICP functions into a single
one, which will introduce the concept of the numerator. That will make
a lot more sense when you read the "num/frac = den" calculation.

Due to the constant alpha we're going to have to program two of
the the tree keying registers anyway, so might as well always
program all three.
And parametrize the plane constant alpha define while at it.

Defined the plane input csc coefficient registers and macros.
6 registers are used to program a total of 9 coefficients,
added macros to define each of them for all the planes
supporting the feature on pipes. On ICL, bottom 3 planes
have this capability.
v2: Segregated the register macro definition as separate patch
as per Maarten's suggestion.
v3: Removed a redundant 3rd Pipe register definition and
simplified the equally spaced register definition by adding an
offset as per Matt's comment.
v4: No Change
v5: Renamed the register Macro as per Matt's suggestion.
v6: No Change
v7: No Change
v8: No Change
v9: No Change
