Instead of looking at drm_plane_state, look at intel_plane_state directly.
This will allow us to make the watermarks bigjoiner aware, when we make it
work for bigjoiner slave pipes as well.

There was a integer wraparound when mode_clock became too high,
and we didn't correct for the FEC overhead factor when dividing,
with the calculations breaking at HBR3.
As a result our calculated bpp was way too high, and the link width
limitation never came into effect.
Print out the resulting bpp calcululations as a sanity check, just
in case we ever have to debug it later on again.
We also used the wrong factor for FEC. While bspec mentions 2.4%,
all the calculations use 1/0.972261, and the same ratio should be
applied to data M/N as well, so use it there when FEC is enabled.
This fixes the FIFO underrun we are seeing with FEC enabled.
Changes since v2:
- Handle fec_enable in intel_link_compute_m_n, so only data M/N is adjusted. (Ville)
- Fix initial hardware readout for FEC. (Ville)
Changes since v3:
- Remove bogus fec_to_mode_clock. (Ville)
Changes since v4:
- Use the correct register for icl. (Ville)
- Split hw readout to a separate patch.

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.

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)

Convert the code that operates directly on gen11 combo PHY's to use the
new namespace. Combo PHY registers are those named "ICL_PORT_*" plus
ICL_DPHY_CHKN.
Note that a lot of the PHY programming happens in the MIPI DSI code.
For clarity I've added a for_each_dsi_phy() to loop over the phys used
by DSI. Since DSI always uses A & B on gen11, port=phy in all cases so
it doesn't actually matter which form we use in the DSI code. I've used
the phy iterator in code that's explicitly working with the combo PHY,
but left the rest of the DSI code using the port iterator and namespace
to minimize patch deltas. We can switch the rest of the DSI code over
to use phy terminology later if this winds up being too confusing.
v6: Drop an include of drm/i915_drm.h; that was previously included just
for the definition of 'enum port' which this patch removes the need

Our past DDI-based Intel platforms have had a fixed DDI<->PHY mapping.
Because of this, both the bspec documentation and our i915 code has used
the term "port" when talking about either DDI's or PHY's; it was always
easy to tell what terms like "Port A" were referring to from the
context.
Unfortunately this is starting to break down now that EHL allows PHY-A
to be driven by either DDI-A or DDI-D. Is a setup with DDI-D driving
PHY-A considered "Port A" or "Port D?" The answer depends on which
register we're working with, and even the bspec doesn't do a great job
of clarifying this.
Let's try to be more explicit about whether we're talking about the DDI
or the PHY on gen11+ by using 'port' to refer to the DDI and creating a
new 'enum phy' namespace to refer to the PHY in use.
This patch just adds the new PHY namespace, new phy-based versions of
intel_port_is_*(), and a helper to convert a port to a PHY.
Transitioning various areas of the code over to using the PHY namespace
will be done in subsequent patches to make review easier. We'll remove
the intel_port_is_*() functions at the end of the series when we
transition all callers over to using the PHY-based versions.
v2:
- Convert a few more 'port' uses to 'phy.' (Sparse)
v3:
- Switch DDI_CLK_SEL() back to 'port.' (Jose)
- Add a code comment clarifying why DPCLKA_CFGCR0_ICL needs to use PHY
for its bit definitions, even though the register description is
given in terms of DDI.
- To avoid confusion, switch CNL's DPCLKA_CFGCR0 defines back to using
port and create separate ICL+ definitions that work in terms of PHY.
v4:
- Rebase and resolve conflicts with Imre's TC series.
- This patch now just adds the namespace and a few convenience
functions; the important changes are now split out into separate
patches to make review easier.

The TypeC port mode can switch dynamically, to reflect that better call
the port's mode as 'mode' rather than 'type'.
While at it:
- s/TC_PORT_TBT/TC_PORT_TBT_ALT/ and s/TC_PORT_TYPEC/TC_PORT_DP_ALT/.
'TYPEC' is ambiguous, TBT_ALT and DP_ALT better match the reality.
- Remove the 'unknown' TypeC port mode. The mode is always known, it's
the TBT-alt/safe mode after HW reset and after disconnecting the PHY.
Simplify the tc_port/tc_type checks accordingly.
- Don't WARN if the port mode changes, that can happen normally.
No functional changes.
