e2512172d1 drm: atmel-hlcdc: Use __drm_atomic_helper_plane_reset instead of copying the logic
A new helper function(__drm_atomic_helper_plane_reset) has been added
for linking a plane with its state and resetting the core
properties(alpha, rotation, etc.) to their default values.
Use that instead of duplicating the logic.

__drm_atomic_helper_plane_reset initializes the alpha property to its
max value, which is defined by the drm core as DRM_BLEND_ALPHA_OPAQUE,
so nothing changes regarding the alpha value.

952a08a21a drm/atmel-hlcdc: Stop using plane->fb
We want to get rid of plane->fb on atomic drivers. Stop looking at it.

Daniel pointed out that the drm_framebuffer_put() in the plane cleanup
indicates that the driver doesn't shut things down cleanly. To do
that we should be able to just call drm_atomic_helper_shutdown(). Not
really sure the current cleanup sequence is actually sane, but whatever.

v2: Replace the drm_framebuffer_put() with
    drm_atomic_helper_shutdown() (Daniel)

e6fc3b6855 drm: Plumb modifiers through plane init
This is the plumbing for supporting fb modifiers on planes. Modifiers
have already been introduced to some extent, but this series will extend
this to allow querying modifiers per plane. Based on this, the client to
enable optimal modifications for framebuffers.

This patch simply allows the DRM drivers to initialize their list of
supported modifiers upon initializing the plane.

v2: A minor addition from Daniel

v3:
* Updated commit message
* s/INVALID/DRM_FORMAT_MOD_INVALID (Liviu)
* Remove some excess newlines (Liviu)
* Update comment for > 64 modifiers (Liviu)

v4: Minor comment adjustments (Liviu)

v5: Some new platforms added due to rebase

v6: Add some missed plane inits (or maybe they're new - who knows at
this point) (Daniel)

c2c446ad29 drm: Add DRM_MODE_ROTATE_ and DRM_MODE_REFLECT_ to UAPI
Add DRM_MODE_ROTATE_ and DRM_MODE_REFLECT_ defines to the UAPI
as a convenience.

Ideally the DRM_ROTATE_ and DRM_REFLECT_ property ids are looked up
through the atomic API, but realizing that userspace is likely to take
shortcuts and assume that the enum values are what is sent over the
wire.

As a result these defines are provided purely as a convenience to
userspace applications.

Changes since v3:
 - Switched away from past tense in comments
 - Add define name change to previously mis-spelled DRM_REFLECT_X comment
 - Improved the comment for the DRM_MODE_REFLECT_<axis> comment

Changes since v2:
 - Changed define prefix from DRM_MODE_PROP_ to DRM_MODE_
 - Fix compilation errors
 - Changed comment formatting
 - Deduplicated comment lines
 - Clarified DRM_MODE_PROP_REFLECT_ comment

Changes since v1:
 - Moved defines from drm.h to drm_mode.h
 - Changed define prefix from DRM_ to DRM_MODE_PROP_
 - Updated uses of the defines to the new prefix
 - Removed include from drm_rect.c
 - Stopped using the BIT() macro

9a45d33cdf drm/atmel-hlcdc: Simplify the HLCDC layer logic
An HLCDC layers in Atmel's nomenclature is either a DRM plane or a 'Post
Processing Layer' which can be used to output the results of the HLCDC
composition in a memory buffer.

atmel_hlcdc_layer.c was designed to be generic enough to be re-usable in
both cases, but we're not exposing the post-processing layer yet, and
even if we were, I'm not sure the code would provide the necessary tools
to manipulate this kind of layer.

Moreover, the code in atmel_hlcdc_{plane,layer}.c was designed before the
atomic modesetting API, and was trying solve the
check-setting/commit-if-ok/rollback-otherwise problem, which is now
entirely solved by the existing core infrastructure.

And finally, the code in atmel_hlcdc_layer.c is over-complicated compared
to what we really need. This rework is a good excuse to simplify it. Note
that this rework solves an existing resource leak (leading to a -EBUSY
error) which I failed to clearly identify.

cd2523569a drm: Always prepare null framebuffer in transitional helper
Despite the documentation claim that cleanup_fb will match prior calls
to prepare_fb, in case of NULL framebuffers in the transitional helpers,
the code will skip the call to prepare_fb but not the corresponding
cleanup_fb call.  This asymmetry in semantics is unnecessarily surprising
for developers transitioning drivers to atomic model, specially because
the final atomic handlers don't have the issue - the prepare_fb is
always called, despite the new state framebuffer being null.

The only current user of the transitional helper that doesn't take care
of null framebuffers explicitly inside the prepare_fb hook is
atmel_hlcdc, so we take special care to make sure we don't break
anything there.

b0b3b79511 drm: Pass 'name' to drm_universal_plane_init()
Done with coccinelle for the most part. It choked on
msm/mdp/mdp5/mdp5_plane.c like so:
"BAD:!!!!!  enum drm_plane_type type;"
No idea how to deal with that, so I just fixed that up
by hand.

Also it thinks '...' is part of the semantic patch, so I put an
'int DOTDOTDOT' placeholder in its place and got rid of it with
sed afterwards.

I didn't convert drm_plane_init() since passing the varargs through
would mean either cpp macros or va_list, and I figured we don't
care about these legacy functions enough to warrant the extra pain.

Use cases like rotation require these hooks to have some context so they

For i915 specifically, object backing pages need to be mapped differently
for different rotation modes and the driver needs to know which mapping to
instantiate and which to tear down when transitioning between them.

5957017db0 drm: atmel-hlcdc: add discard area support
The HLCDC IP provides a way to discard a specific area on the primary
plane (in case at least one of the overlay is activated and alpha
blending is disabled).
Doing this will reduce the amount of data to transfer from the main
memory to the Display Controller, and thus alleviate the load on the
memory bus (since this link is quite limited on such hardware,
this kind of optimization is really important).

The Atmel HLCDC (HLCD Controller) IP available on some Atmel SoCs (i.e.
at91sam9n12, at91sam9x5 family or sama5d3 family) provides a display
controller device.

This display controller supports at least one primary plane and might
provide several overlays and an hardware cursor depending on the IP
version.

At the moment, this driver only implements an RGB connector to interface
with LCD panels, but support for other kind of external devices might be
added later.
