Latency programming remains same as that of ICL and
setting latency otimization for PCS_DW1 lanes is same as
that of EHL, hence extending it to TGL.

Increase abstraction of display suspend/resume operations by providing
higher level functions, and hiding the details inside
intel_display_power.c.
v2: Make checkpatch happy:
- braces {} are not necessary for single statement blocks
v3: Also move hsw/bdw PC8 sequences since they are related to
display PM anyways. (Ville)
v4: Rebase after a long time, plus Move functions to the new
intel_display_power so we can stop exporting platform specific
functions as pointed by Jani.
v5: Remove unnecessary braces.
v6 by Jani: make this purely non-functional cleanup, make functions static

Everything about the file is about display, and mostly about types
related to display. Move under display/ as intel_display_types.h to

There's still plenty to clean up, but start off with moving the file

A single 32-bit PSR2 training pattern field follows the sixteen element
array of PSR table entries in the VBT spec. But, we incorrectly define
this PSR2 field for each of the PSR table entries. As a result, the PSR1
training pattern duration for any panel_type != 0 will be parsed
incorrectly. Secondly, PSR2 training pattern durations for VBTs with bdb
version >= 226 will also be wrong.

On VLV/CHV there is some kind of linkage between the cdclk frequency
and the DP link frequency. The spec says:
"For DP audio configuration, cdclk frequency shall be set to
meet the following requirements:
DP Link Frequency(MHz) | Cdclk frequency(MHz)
270 | 320 or higher
162 | 200 or higher"
I suspect that would more accurately be expressed as
"cdclk >= DP link clock", and in any case we can express it like
that in the code because of the limited set of cdclk (200, 266,
320, 400 MHz) and link frequencies (162 and 270 MHz) we support.
Without this we can end up in a situation where the cdclk
is too low and enabling DP audio will kill the pipe. Happens
eg. with 2560x1440 modes where the 266MHz cdclk is sufficient
to pump the pixels (241.5 MHz dotclock) but is too low for
the DP audio due to the link frequency being 270 MHz.
v2: Spell out the cdclk and link frequencies we actually support

Right now we are aware of two cases that needs another hotplug retry:
- Unpowered type-c dongles
- HDMI slow unplug
Both have a complete explanation in the code to schedule another run
of the hotplug handler.
It could have more checks to just trigger the retry in those two
specific cases but why would sink signal a long pulse if there is
no change? Also the drawback of running the hotplug handler again
is really low and that could fix another cases that we are not
aware.
Also retrying for old DP ports(non-DDI) to make it consistent and not
cause CI failures if those systems are connected to chamelium boards
that will be used to simulate the issues reported in here.
v2: Also retrying for old DP ports(non-DDI)(Imre)
v4: Renamed INTEL_HOTPLUG_NOCHANGE to INTEL_HOTPLUG_UNCHANGED to keep
it consistent(Rodrigo)

Now that we distinguish between phy and port(ddi), mcc_port_to_ddc_pin

We're only converting the MCC function at the moment since EHL is the

Some platforms may have Modular FIA. If Modular FIA is used in the SOC,
then Display Driver will access the additional instances of
FIA based on pre-assigned offset in GTTMADDR space.
Each Modular FIA instance has its own IOSF Sideband Port ID
and it houses only 2 Type-C Port. In SOC that has more than
two Type-C Ports, there are multiple instances of Modular FIA.
Gunit will need to use different destination ID when it access
different pair of Type-C Port.
The DFLEXDPSP register has Modular FIA bit starting on Tiger Lake. If
Modular FIA is used in the SOC, this register bit exists in all the
instances of Modular FIA. IOM FW is required to program only the MF bit
in first FIA instance that houses the Type-C Port 0 and Port 1, for
Display Driver to read from.
v2 (Lucas):
- Move all accesses to FIA to be contained in intel_tc.c, along with
display_fia that is now called tc_phy_fia
- Save the fia instance number on intel_digital_port, so we don't have
to query if modular FIA is used on every access
v3 (Lucas): Make function static
v4 (Lucas): Move enum phy_fia to the header and use it in
intel_digital_port (suggested by Ville)
v5 (Lucas): Add comment about the mapping between FIA and TC port
(suggested by Stuart)

I checked if this could not apply to EHL as well, but unfortunately
there the HPD and DDC/GMBUS pins for DDI C are mapped to TypeC Port 1
even though it doesn't have TC phy.
v2: don't add a separate function for TGL, but rather reuse the ICL one

The patch adds the new power wells introduced by TGL (GEN 12) and
maps these to existing/new power domains. The changes for GEN 12 wrt
to GEN 11 are the following:
- Transcoder#EDP removed from power well#1 (Transcoder#A used in
low-power mode instead)
- Transcoder#A is now backed by power well#1 instead of power well#3
- The DDI#B/C combo PHY ports are now backed by power well#1 instead of
power well#3
- New power well#5 added for pipe#D functionality (TODO)
- 2 additional TC ports (TC#5-6) backed by power well#3, 2 port
specific IO power wells (only for the non-TBT modes) and 4 port
specific AUX power wells (2-2 for TBT vs. non-TBT modes)
- Power well#2 backs now VDSC/joining for pipe#A instead of VDSC for
eDP and MIPI DSI (TODO)
On TGL Port DDI#C changed to be a combo PHY (native DP/HDMI) and
BSpec has renamed ports DDI#D-F to TC#4-6 respectively. Thus on ICL we
have the following naming for ports:
- Combo PHYs (native DP/HDMI):
DDI#A-B
- TBT/non-TBT (TC altmode, native DP/HDMI) PHYs:
DDI#C-F
Starting from GEN 12 we have the following naming for ports:
- Combo PHYs (native DP/HDMI):
DDI#A-C
- TBT/non-TBT (TC altmode, native DP/HDMI) PHYs:
DDI TC#1-6
To save some space in the power domain enum the power domain naming in
the driver reflects the above change, that is power domains TC#1-3 are
added as aliases for DDI#D-F and new power domains are reserved for
TC#4-6.
v2 (Lucas):
- Separate out the bits and definitions for TGL from the ICL ones.
Fix use of TRANSCODER_EDP_VDSC, that is now the correct define since
we don't define TRANSCODER_A_VDSC power domain to spare a one bit in
the bitmask (suggested by Ville)
v3 (Lucas):
- Fix missing squashes on v2
- Rebase on renamed TRANSCODER_EDP_VDSC

On TGL the special EDP transcoder is gone and it should be handled by
transcoder A.
v2 (Lucas):
- Reuse POWER_DOMAIN_TRANSCODER_EDP_VDSC (suggested by Ville)
- Use crtc->dev since new_crtc_state->state may be NULL on atomic
commit (suggested by Maarten)
v3 (Lucas):
- Rename power domain so it's clear it can also be used for transcoder
A in TGL (requested by José and Manasi)
