objtool, drm/vmwgfx: Fix "duplicate frame pointer save" warning
Provides helper functions for drivers that have a simple display
pipeline. Plane, crtc and encoder are collapsed into one entity.
Changes since v4:
- Remove drm_connector_register() call
- Forgot to assign pipe->connector
Changes since v3:
- (struct drm_simple_display_pipe *)->funcs should be const
Changes since v2:
- Drop Kconfig knob DRM_KMS_HELPER
- Expand documentation
Changes since v1:
- Add DOC header and add to gpu.tmpl
- Fix docs: @funcs is optional, "negative error code",
"This hook is optional."
- Add checks to drm_simple_kms_plane_atomic_check()

We have a 1:1 relationship between connectors and encoders, which means
we can rely on the drm_atomic_helper_best_encoder() behavior.
We still have to explicitly assign ->best_encoder() to
drm_atomic_helper_best_encoder(), because the automated fallback to
drm_atomic_helper_best_encoder() when ->best_encoder() is NULL is only
available when the DRM device is using the atomic helpers, and this bridge
is compatible with non-atomic and atomic devices.

With the various bits fixed rockchip now has an atomic compliant
handling/signalling of crtc_state->event, which means we can just
switch over to the new nonblocking helpers and remove some code.
v2: Fixes from Tomeu.
v3: Send out vblank events correctly when shutting down a crtc for
good. This is part of the atomic interface contract.
v4: Properly protect vop->event.
v5: Add more WARN_ON to check vop->event isn't clobbered.

Design ideas:
- split up the actual commit into different phases, and have
completions for each of them. This will be useful for the future
when we want to interleave phases much more aggressively, for e.g.
queue depth > 1. For not it's just a minimal optimization compared
to current common nonblocking implementation patterns from drivers,
which all stall for the entire commit to complete, including vblank
waits and cleanups.
- Extract a separate atomic_commit_hw hook since that's the part most
drivers will need to overwrite, hopefully allowing even more shared
code.
- Enforce EBUSY seamntics by attaching one of the completions to the
flip_done vblank event. Side benefit of forcing atomic drivers using
these helpers to implement event handlign at least semi-correct. I'm
evil that way ;-)
- Ridiculously modular, as usual.
- The main tracking unit for a commit stays struct drm_atomic_state,
and the ownership rules for that are unchanged. Ownership still
gets transferred to the driver (and subsequently to the worker) on
successful commits. What is added is a small, per-crtc, refcounted
structure to track pending commits called struct drm_crtc_commit.
No actual state is attached to that though, it's purely for ordering
and waiting.
- Dependencies are implicitly handled by assuming that any CRTC part
of &drm_atomic_state is a dependency, and that the current commit
must wait for any commits to complete on those CRTC. This way
drivers can easily add more depencies using
drm_atomic_get_crtc_state(), which is very natural since in most
case a dependency exists iff there's some bit of state that needs to
be cross checked.
Removing depencies is not possible, drivers simply need to be
careful to not include every CRTC in a commit if that's not
necessary. Which is a good idea anyway, since that also avoids
ww_mutex lock contention.
- Queue depth > 1 sees some prep work in this patch by adding a stall
paramater to drm_atomic_helper_swap_states(). To be able to push
commits entirely free-standing and in a deeper queue through the
back-end the driver must not access any obj->state pointers. This
means we need to track the old state in drm_atomic_state (much
easier with the consolidated arrays), and pass them all explicitly
to driver backends (this will be serious amounts of churn).
Once that's done stall can be set to false in swap_states.
v2: Dont ask for flip_done signalling when the CRTC is off and stays
off: Drivers don't handle events in that case. Instead complete right
away. This way future commits don't need to have special-case logic,
but can keep blocking for the flip_done completion.
v3: Tons of fixes:
- Stall for preceeding commit for real, not the current one by
accident.
- Add WARN_ON in case drivers don't fire the drm event.
- Don't double-free drm events.
v4: Make legacy cursor not stall.
v5: Extend the helper hook to cover the entire commit tail. Some
drivers need special code for cleanup and vblank waiting, this makes
it a bit more useful. Inspired by the rockchip driver.
v6: Add WARN_ON to catch drivers who forget to send out the
drm event.
v7: Fixup the stalls in swap_state for real!!
v8:
- Fixup trailing whitespace, spotted by Maarten.
- Actually wait for flip_done in cleanup_done, like the comment says
we should do. Thanks a lot for Tomeu for helping with debugging this
on.
v9: Now with awesome kerneldoc!
v10: Split out drm_crtc_commit tracking infrastructure.
v:
- Add missing static (Gustavo).
- Split out the sync functions, only do the actual nonblocking
logic in this patch (Maarten).

To facilitate easier reviewing this is split out from the overall
nonblocking commit rework. It just rolls out the helper functions
and uses them in the main drm_atomic_helper_commit() function
to make it clear where in the flow they're used.
The next patch will actually split drm_atomic_helper_commit() into
2 pieces, with the tail being run asynchronously from a worker.
v2: Improve kerneldocs (Maarten).
v3: Don't convert ERESTARTSYS to EINTR (Maarten). Also don't fail if
the wait succeed in stall_check - we need to convert that case (it
returns the remaining jiffies) to 0 for success.
v4: Switch to long for wait_for_completion_timeout return value
everywhere (Maarten).
v5: Fix miscaped function in kerneldoc (Maarten).

Apparently some CHV boards failed to hook up the port presence straps
for HDMI ports as well (earlier we assumed this problem only affected
eDP ports). So let's check the VBT in addition to the strap, and if
either one claims that the port is present go ahead and register the
relevant connector.
While at it, change port D to register DP before HDMI as we do for ports
B and C since
commit 457c52d87e ("drm/i915: Only ignore eDP ports that are connected")
Also print a debug message when we register a HDMI connector to aid
in diagnosing missing/incorrect ports. We already had such a print for
DP/eDP.
v2: Improve the comment in the code a bit, note the port D change in
the commit message
