Zero initialize val2 so that we don't pass stack garbage to

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
for. (Jose)

Although the register name implies that it operates on DDI's,
DPCLKA_CFGCR0_ICL actually needs to be programmed according to the PHY
that's in use. I.e., when using EHL's DDI-D on combo PHY A, the bits
described as "port A" in the bspec are what we need to set. The bspec
clarifies:
"[For EHL] DDID clock tied to DDIA clock, so DPCLKA_CFGCR0 DDIA
Clock Select chooses the PLL for both DDIA and DDID and drives
port A in all cases."
Also, since the CNL DPCLKA_CFGCR0 bit defines are still port-based, we
create separate ICL-specific defines that accept the PHY rather than
trying to share the same bit definitions between CNL and ICL.
v5: Make icl_dpclka_cfgcr0_clk_off() take phy rather than port. When
splitting the original patch the hunk to handle this wound up too
late in the series. (Sparse)
v6: Since we're already changing this code,
s/DPCLKA_CFGCR0_ICL/ICL_DPCLKA_CFGCR0/ for consistency. (Jose)

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.

PORT_TX_DFLEXDPMLE1 is a FIA register so move it to intel_tc.c where we
access other FIA registers. In Tiger Lake we have multiple/modular FIAs
so it makes sense to start moving all access to their registers to a
common place.
While at it, make it clear that we will only ever call this function
for ports with TC phy. Previously we were relying on tc_mode being
TC_PORT_TBT_ALT for combo phy ports. However it's confusing since in
this same function we have checks for is_tc_port. Also, if we manage to
make each phy access only their own field, we may in future add them as
a union inside intel_digital_port.

For consistency clear the icl_port_dplls from the new crtc state, when
releasing the DPLLs from the old crtc state. Leaving them set could
result in releasing the same PLLs multiple times from the same CRTC
state incorrectly (if the same CRTC was first used for a TypeC port then
for a combo PHY port).
Leaving the stale pointers behind happens not to cause a problem atm
(since the incorrect releasing will be a NOP), but we need to fix that
for consistency.

This patch adds support for DPLL4 on EHL that include the
following restrictions:
- DPLL4 cannot be used with DDIA (combo port A internal eDP usage).
DPLL4 can be used with other DDIs, including DDID
(combo port A external usage).
- DPLL4 cannot be enabled when DC5 or DC6 are enabled.
- The DPLL4 enable, lock, power enabled, and power state are connected
to the MGPLL1_ENABLE register.
v2: (suggestions from Bob Paauwe)
- Rework ehl_get_dpll() function to call intel_find_shared_dpll() and
iterate twice: once for Combo plls and once for MG plls.
- Use MG pll funcs for DPLL4 instead of creating new ones and modify
mg_pll_enable to include the restrictions for EHL.
v3: Fix compilation error
v4: (suggestions from Lucas and Ville)
- Treat DPLL4 as a combo phy PLL and not as MG PLL
- Disable DC states when this DPLL is being enabled
- Reuse icl_get_dpll instead of creating a separate one for EHL
v5: (suggestion from Ville)
- Refcount the DC OFF power domains during the enabling and disabling
of this DPLL.
v6: rebase
v7: (suggestion from Imre)
- Add a new power domain instead of iterating over the domains
assoicated with DC OFF power well.
v8: (Ville and Imre)
- Rename POWER_DOMAIN_DPLL4 TO POWER_DOMAIN_DPLL_DC_OFF
- Grab a reference in intel_modeset_setup_hw_state() if this
DPLL was already enabled perhaps by BIOS.
- Check for the port type instead of the encoder
v9: (Ville)
- Move the block of code that grabs a reference to the power domain
POWER_DOMAIN_DPLL_DC_OFF to intel_modeset_readout_hw_state() to ensure
that there is a reference present before this DPLL might get disabled.
v10: rebase

Split the format lists for different planes on skl/icl more cleanly.
On skl+ we have just two types of planes: those can do planar and
those that can't.
On icl we have three types of planes: hdr planes, sdr planes that
can do planar, and sdr planes that can't do planar. Those latter two
are the same set of planes we must when choose from when picking the
UV vs. Y plane for planar scanout. So we shall just designate
them sdr uv planes and sdr y planes.

All sprite planes have a progammable gamma ramp. Set it up with
a linear ramp on all platforms. This actually matches the reset
value but soon we'll want to reprogram this ramp on some machines,
so let's just set it up across the board.
Note that on pre-IVB the hardware bypasses the gamma unit
unless a YCbCr pixel format is used.

We don't currently have any use for the sprite gamma on ivb-bdw.
Let's disable it. We already do that on skl+.
On pre-ivb there is no way to disable the sprite gamma, and it
only affects YCbCr pixel formats, whereas on ivb+ it also
affects RGB formats.

Plane B and C (note that we don't actually expose plane C currently)
on gen2/3 have a window generator, as does the primary plane on CHV
pipe B. So let's allow positioning of these planes freely within the
pipe source area.
Plane A on gen2/3 seems to have some kind of partial window generator
which would allow you to cut the plane off midway through the scanout,
but it would still have to start at the top-left corner of the pipe,
and it would have to be full width. That's doesn't sound all that
useful, so for simplicity let's just keep to the idea that plane A
has to be fullscreen.
Gen4 removed the plane A/B windowing support entirely, and it wasn't
reintroduced until SKL (apart from the CHV pipe B special case).

When SAGV is forced to disabled/min/med/max in the BIOS pcode will
only hand us a single QGV point instead of the normal three. Fix
the code to deal with that instead declaring the bandwidth limit
to be 0 MB/s (and thus preventing any planes from being enabled).
Also shrink the max_bw sturct a bit while at it, and change the
deratedbw type to unsigned since the code returns the bw as
an unsigned int.
Since we now keep track of how many qgv points we got from pcode
we can drop the earlier check added for the "pcode doesn't
support the memory subsystem query" case.

Disconnecting the TypeC PHY when the port is in legacy mode is not
necessary:
- BSpec doesn't specify a disconnect sequence for legacy mode.
- The use of the PHY is dedicated for the display in legacy mode.
- We keep the PHY always connected during runtime as well in legacy
mode.
We disconnect the PHY when needed during a disabling modeset for the
port, so we can also remove the disconnect call from the destroy hook.

The TypeC port mode needs to stay fixed whenever the port is active. Do
that by introducing a tc_link_refcount to account for active ports,
avoiding changing the port mode if a reference is held.
During the modeset commit phase we also have to reset the port mode and
update the active PLL reflecting the new port mode. We can do this only
once the port and its old PLL has been already disabled. Add the new
encoder update_prepare/complete hooks that are called around the whole
enabling sequence. The TypeC specific hooks of these will reset the port
mode, update the active PLL if the port will be active and ensure that
the port mode will stay fixed for the duration of the whole enabling
sequence by holding a tc_link_refcount.
During the port enabling, the pre_pll_enable/post_pll_disable hooks will
take/release a tc_link_refcount to ensure the port mode stays fixed
while the port is active.
Changing the port mode should also be avoided during connector detection
and AUX transfers if the port is active, we'll do that by checking the
port's tc_link_refcount.
When resetting the port mode we also have to take into account the
maximum lanes provided by the FIA. It's guaranteed to be 4 in TBT-alt
and legacy modes, but there may be less lanes available in DP-alt mode,
in which case we have to fall back to TBT-alt mode.
While at it also update icl_tc_phy_connect()'s code comment, reflecting
the current way of switching the port mode.
v2:
- Add the update_prepare/complete hooks to the encoder instead of the
connector. (Ville)
- Simplify intel_connector_needs_modeset() by removing redundant if.
(Ville)
v3:
- Fix sparse warning, marking static functions as such.
v4:
- Rebase on drm-tip.
