drm/i915/tgl: rename TRANSCODER_EDP_VDSC to use on transcoder A

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)

drm/i915: Copy name string into ring buffer for intel_update/disable_plane tracepoints

Currently the intel_update_plane and intel_disable_plane tracepoints record
the address of plane->name in the ring buffer, and then when reading the
ring buffer uses %s to get the name. The issue with this, is that those two
events can be minutes, hours or even days apart. It is very dangerous to
dereference a string pointer without knowing if it still exists or not.

The proper way to handle this is to use the __string() macro in the
tracepoint which will save the string into the ring buffer at the time of
recording. Then there's no worries if the original string still exists in
memory when the ring buffer is read.

drm/i915/gen11: Program ICL_DPCLKA_CFGCR0 according to PHY

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.

drm/i915/gen11: Start distinguishing 'phy' from 'port'

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

 - To avoid confusion, switch CNL's DPCLKA_CFGCR0 defines back to using

drm/i915: move intel_ddi_set_fia_lane_count to intel_tc.c

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.

drm/i915/ehl: Add support for DPLL4 (v10)

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

drm/i915: Clean up skl vs. icl plane formats

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

drm/i915: Add windowing for primary planes on gen2/3 and chv

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).

Expose whether or not we support the PMU software tracking in our

drm/i915/gem: Defer obj->base.resv fini until RCU callback

Since reservation_object_fini() does an immediate free, rather than
kfree_rcu as normal, we have to delay the release until after the RCU
grace period has elapsed (i.e. from the rcu cleanup callback) so that we
can rely on the RCU protected access to the fences while the object is a
zombie.

i915_gem_busy_ioctl relies on having an RCU barrier to protect the
reservation in order to avoid having to take a reference and strong
memory barriers.

v2: Order is important; only release after putting the pages!

The intent of the assert is to document that the caller took the
appropriate wakerefs for the function. However, as Tvrtko pointed out,
we simply check whether the fw_domains are active and may be confused by
the auto wakeref which may be dropped between the check and use. Let's
be more careful in the assert and check that each fw_domain has an
explicit caller wakeref above and beyond the automatic wakeref.

v2: Fix spelling for config DRM_I915_DEBUG_RUNTIME_PM
v3: Timer may still be active after we drop the autowakeref, we need to
check domain->active instead.
v4: The timer checks domain->active, but we still need to check the
timer. (This is starting to look weird...)

- since the overlay and video planes use essentially the same format
  registers, precompute their values while validating.

- calculate plane starting address at atomic_check stage rather than
  when we're programming the registers.
- add gamma support.
- ensure mode adjustments made by other components are properly handled
  in the driver and applied to the CRTC-programmed mode.
- add and use register definitions for the "REG4F" register.
- use drm_atomic_helper_shutdown() when tearing down to ensure that the
  hardware is properly shutdown.
- add CRTC-level mode validation to ensure that we don't allow a mode
  that the CRTC-level hardware can not support.
- improve the clocking selection for Armada 510 support.
- move CRTC debugfs files into the crtc-specific directory, using the
  DRM helper to create these files.
- patch from Lubomir Rintel to replace a simple framebuffer.
- use the OF graph walker rather than open-coding this.
- eliminate a useless check for the availability of the remote's parent
  which isn't required.
