This patch makes the internal encoder implementation of the simple
KMS helpers available to drivers.
These simple-encoder helpers initialize an encoder with an empty
implementation. This covers the requirements of most of the existing
DRM drivers. A call to drm_simple_encoder_create() allocates and
initializes an encoder instance, a call to drm_simple_encoder_init()
initializes a pre-allocated instance.
v3:
* remove drm_simple_encoder_create(); not required yet
* provide more precise documentation
v2:
* move simple encoder to KMS helpers
* remove name argument; simplifies implementation
* don't allocate with devm_ interfaces; unsafe with DRM

Most bridge drivers create a DRM connector to model the connector at the
output of the bridge. This model is historical and has worked pretty
well so far, but causes several issues:
- It prevents supporting more complex display pipelines where DRM
connector operations are split over multiple components. For instance a
pipeline with a bridge connected to the DDC signals to read EDID data,
and another one connected to the HPD signal to detect connection and
disconnection, will not be possible to support through this model.
- It requires every bridge driver to implement similar connector
handling code, resulting in code duplication.
- It assumes that a bridge will either be wired to a connector or to
another bridge, but doesn't support bridges that can be used in both
positions very well (although there is some ad-hoc support for this in
the analogix_dp bridge driver).
In order to solve these issues, ownership of the connector should be
moved to the display controller driver (where it can be implemented
using helpers provided by the core).
Extend the bridge API to allow disabling connector creation in bridge
drivers as a first step towards the new model. The new flags argument to
the bridge .attach() operation allows instructing the bridge driver to
skip creating a connector. Unconditionally set the new flags argument to
0 for now to keep the existing behaviour, and modify all existing bridge
drivers to return an error when connector creation is not requested as
they don't support this feature yet.
The change is based on the following semantic patch, with manual review
and edits.

We are about to add a drm_bridge_state that inherits from
drm_private_state which is defined in drm_atomic.h. Problem is,
drm_atomic.h includes drm_crtc.h which in turn includes drm_bridge.h,
leading to "drm_private_state has incomplete type" error.
Let's force all users of the drm_bridge API to explicitly include
drm_bridge.h.

Having the probe helper stuff (which pretty much everyone needs) in
the drm_crtc_helper.h file (which atomic drivers should never need) is
confusing. Split them out.
To make sure I actually achieved the goal here I went through all
drivers. And indeed, all atomic drivers are now free of
drm_crtc_helper.h includes.
v2: Make it compile. There was so much compile fail on arm drivers
that I figured I'll better not include any of the acks on v1.
v3: Massive rebase because i915 has lost a lot of drmP.h includes, but
not all: Through drm_crtc_helper.h > drm_modeset_helper.h -> drmP.h
there was still one, which this patch largely removes. Which means
rolling out lots more includes all over.
This will also conflict with ongoing drmP.h cleanup by others I
expect.
v3: Rebase on top of atomic bochs.
v4: Review from Laurent for bridge/rcar/omap/shmob/core bits:
- (re)move some of the added includes, use the better include files in
other places (all suggested from Laurent adopted unchanged).
- sort alphabetically
v5: Actually try to sort them, and while at it, sort all the ones I
touch.
v6: Rebase onto i915 changes.
v7: Rebase once more.

because drm_simple_kms_helper.drm_crtc_funcs does not provide any.
At the same time drm_driver.{enable|disable}_vblank callbacks
are marked as deprecated and shouldn't be used by new drivers.

Note that this replaces crtc_state->adjusted_mode usage with

You can enable the CRTC and without adding the plane to the state and
it will succeed. This should be prevented in the crtc check instead of
the plane check, because the plane check may never run for atomic

This is based on a similar check in vmwgfx.

Like the atomic update hook it's wrapping, the plane_state is the old
one, and the new one is in plane->state. Both msxfb and tinydrm use
it correctly, but I mistook it for the new state in pl111 due to its
naming.

This is a straightforward conversion that converts all the users of
get_existing_state in atomic core to use get_old_state or get_new_state
Changes since v1:
- Fix using the wrong state in drm_atomic_helper_update_legacy_modeset_state.
Changes since v2:
- Use the correct state in disable_outputs()
Changes since v3:
- Rebase for link status training.

sed -e 's/\( \* .*\)struct &\([_a-z]*\)/\1\&struct \2/' -i
Originally I wasnt a friend of this style because I thought a
line-break between the "&struct" and "foo" part would break it. But a
quick test shows that " * &struct \n * foo\n" works pefectly well with
current kernel-doc. So time to mass-apply these changes!

Most drivers that use bridges forgot to detach them at cleanup time.
Instead of fixing them one by one, detach the bridge in the core
drm_encoder_cleanup() function.

Instead of linking encoders and bridges in every driver (and getting it
wrong half of the time, as many drivers forget to set the drm_bridge
encoder pointer), do so in core code. The drm_bridge_attach() function
needs the encoder and optional previous bridge to perform that task,
update all the callers.

Add .prepare_fb and .cleanup_fb plane hooks into the drm_simple_kms.
These can be used by drivers to call ie. the drm_fb_cma_setup_fence()

drm_simple_display_pipe_init() pretends to attach a connector
to the display pipe.
In case a drm bridge has to be used, then it's the bridge that
takes care of connectors.
This patch makes the connector parameter optional for
drm_simple_display_pipe_init(), so that a drm bridge could
handle connector by itself later.

Our update function is hooked to the single plane, which might not get
called for crtc-only updates. Which is surprising, so fix this by
always adding the plane.
While at it document how&when the event should be sent out better in
the kerneldoc.

drm_plane_helper_check_update() needs to account for the plane rotation
for correct clipping/scaling calculations. Do so.
There was an earlier attempt [1] to add this into
intel_check_primary_plane() but I requested that it'd be put into the
helper instead. An updated patch never materialized AFAICS, so I went
ahead and cooked one up myself.
v2: Deal with new drm_plane_helper_check_update() callers

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()
