Added content_type property to drm_connector_state
in order to properly handle external HDMI TV content-type setting.v2:
* Moved helper function which attaches content type property
to the drm core, as was suggested.
Removed redundant connector state initialization.v3:
* Removed caps in drm_content_type_enum_list.
After some discussion it turned out that HDMI Spec 1.4
was wrongly assuming that IT Content(itc) bit doesn't affect
Content type states, however itc bit needs to be manupulated
as well. In order to not expose additional property for itc,
for sake of simplicity it was decided to bind those together
in same "content type" property.v4:
* Added it_content checking in intel_digital_connector_atomic_check.
Fixed documentation for new content type enum.v5:
* Moved patch revision's description to commit messages.v6:
* Minor naming fix for the content type enumeration string.v7:
* Fix parameter name for documentation and parameter alignment
in order not to get warning. Added Content Type description to
new HDMI connector properties section.v8:
* Thrown away unneeded numbers from HDMI content-type property
description. Switch to strings desription instead of plain
definitions.v9:
* Moved away hdmi specific content-type enum from
drm_connector_state. Content type property should probably not
be bound to any specific connector interface in
drm_connector_state.
Same probably should be done to hdmi_picture_aspect_ration enum
which is also contained in drm_connector_state. Added special
helper function to get derive hdmi specific relevant infoframe
fields.v10:
* Added usage description to HDMI properties kernel doc.v11:
* Created centralized function for filling HDMI AVI infoframe, based
on correspondent DRM property value.Acked-by: Hans Verkuil

This patch adds a new optional connector property to allow userspace to enable
protection over the content it is displaying. This will typically be implemented
by the driver using HDCP.The property is a tri-state with the following values:
- OFF: Self explanatory, no content protection
- DESIRED: Userspace requests that the driver enable protection
- ENABLED: Once the driver has authenticated the link, it sets this valueThe driver is responsible for downgrading ENABLED to DESIRED if the link becomes
unprotected. The driver should also maintain the desiredness of protection
across hotplug/dpms/suspend.If this looks familiar, I posted [1] this 3 years ago. We have been using this
in ChromeOS across exynos, mediatek, and rockchip over that time.Changes in v2:
- Pimp kerneldoc for content_protection_property (Daniel)
- Drop sysfs attribute
Changes in v3:
- None
Changes in v4:
- Changed kerneldoc to recommend userspace polling (Daniel)
- Changed kerneldoc to briefly describe how to attach the property (Daniel)
Changes in v5:
- checkpatch whitespace noise
- Change DRM_MODE_CONTENT_PROTECTION_OFF to DRM_MODE_CONTENT_PROTECTION_UNDESIRED
Changes in v6:

According to ANSI-CTA-861-G specification:
* EOTF is 8 bit, not 16;
* metadata type is 8 bit, not 16;
* There's no "Minimum Content Light Level"This patch will change the HDR metadata structures to reflect that. Also, this
will fix problems seen on some TVs that were rejecting HDR metadata because
it's size was too big (more than 26 bytes).Signed-off-by: Laurentiu Palcu

This change allows userland to create a tee_shm object that refers
to a dmabuf reference.Userland provides a dmabuf file descriptor as buffer reference.
The created tee_shm object exported as a brand new dmabuf reference
used to provide a clean fd to userland. Userland shall closed this new
fd to release the tee_shm object resources. The initial dmabuf resources
are tracked independently through original dmabuf file descriptor.Once the buffer is registered and until it is released, TEE driver
keeps a refcount on the registered dmabuf structure.This change only support dmabuf references that relates to physically
contiguous memory buffers.New tee_shm flag to identify tee_shm objects built from a registered
dmabuf: TEE_SHM_EXT_DMA_BUF. Such tee_shm structures are flagged both
TEE_SHM_DMA_BUF and TEE_SHM_EXT_DMA_BUF.Signed-off-by: Etienne Carriere

drm_mode_create_lease
Creates a lease for a list of drm mode objects, returning an
fd for the new drm_master and a 64-bit identifier for the lesseedrm_mode_list_lesees
List the identifiers of the lessees for a master file
drm_mode_get_lease
List the leased objects for a master file
drm_mode_revoke_lease
Erase the set of objects managed by a lease.
This should suffice to at least create and query leases.
Changes for v2 as suggested by Daniel Vetter :
* query ioctls only query the master associated with
the provided file.* 'mask_lease' value has been removed
* change ioctl has been removed.
Changes for v3 suggested in part by Dave Airlie
* Add revoke ioctl.
Changes for v4 suggested by Dave Airlie
* Expand on the comment about the magic use of &drm_lease_idr_object
* Pad lease ioctl structures to align on 64-bit boundariesChanges for v5 suggested by Dave Airlie
* Check for non-negative object_id in create_lease to avoid debug
output from the kernel.Changes for v6 provided by Dave Airlie
* For non-universal planes add primary/cursor planes to lease
If we aren't exposing universal planes to this userspace client,
and it requests a lease on a crtc, we should implicitly export the
primary and cursor planes for the crtc.If the lessee doesn't request universal planes, it will just see
the crtc, but if it does request them it will then see the plane
objects as well.This also moves the object look ups earlier as a side effect, so
we'd exit the ioctl quicker for non-existant objects.* Restrict leases to crtc/connector/planes.
This only allows leasing for objects we wish to allow.
Changes for v7 provided by Dave Airlie
* Check pad args are 0
* Check create flags and object count are valid.
* Check return from fd allocation
* Refactor lease idr setup and add some simple validation
* Use idr_mutex uniformly (Keith)Signed-off-by: Keith Packard
