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 value
The 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:
- None

Add new standard connector properties to track whether content protection
(ex: hdcp) is desired by userspace. There are two properties involved,
"Content Protection" and "Content Protection KSV".
The "Content Protection" property allows userspace to request protection
on a connector. Set "Desired" to enable, "Undesired" to disable.
The "Content Protection KSV" property reflects the current state of
protection. If the KSV is 0, the connection is not protected. Once the
driver has enabled protection, it will update the the value with the KSV
(or similarly unique identifier, if not using HDCP) of the first-hop
device (sink or repeater).

Patch based on a previous series by Shashank Sharma.
This introduces optional properties to enable color correction at the
pipe level. It relies on 3 transformations applied to every pixels
displayed. First a lookup into a degamma table, then a multiplication
of the rgb components by a 3x3 matrix and finally another lookup into
a gamma table.
The following properties can be added to a pipe :
- DEGAMMA_LUT : blob containing degamma LUT
- DEGAMMA_LUT_SIZE : number of elements in DEGAMMA_LUT
- CTM : transformation matrix applied after the degamma LUT
- GAMMA_LUT : blob containing gamma LUT
- GAMMA_LUT_SIZE : number of elements in GAMMA_LUT
DEGAMMA_LUT_SIZE and GAMMA_LUT_SIZE are read only properties, set by
the driver to tell userspace applications what sizes should be the
lookup tables in DEGAMMA_LUT and GAMMA_LUT.
A helper is also provided so legacy gamma correction is redirected
through these new properties.
v2: Register LUT size properties as range
v3: Fix round in drm_color_lut_get_value() helper
More docs on how degamma/gamma properties are used
v4: Update contributors
v5: Rename CTM_MATRIX property to CTM (Doh!)
Add legacy gamma_set atomic helper
Describe CTM/LUT acronyms in the kernel doc
v6: Fix missing blob unref in drm_atomic_helper_crtc_reset

With the atomic API, it is possible that a single commit affects
multiple crtcs. If the user requests an event with that commit, one
event will be sent for each CRTC, but it is not possible to distinguish
which crtc an event is for in user space. To solve this, the reserved
field in struct drm_vblank_event is repurposed to include the crtc_id
which the event is for.
The DRM_CAP_CRTC_IN_VBLANK_EVENT is added to allow userspace to query if
the crtc field will be set properly.

When doing a atomic commit affecting multiple crtc's, multiple events
are generated. The user_data member does not allow you to distinguish,
because they all have the same pointer.
I've chosen to use crtc_id, because using pipe would create ambiguity
when pipe = 0. A test for != 0 is easier to implement, and crtc_id
will never be 0.

HDMI 2.0 introduces a new sampling mode called YCbCr 4:2:0.
According to the spec the EDID may contain two blocks that
signal this sampling mode:
- YCbCr 4:2:0 Video Data Block
- YCbCr 4:2:0 Video Capability Map Data Block
The video data block contains the list of vic's were
only YCbCr 4:2:0 sampling mode shall be used while the
video capability map data block contains a mask were
YCbCr 4:2:0 sampling mode may be used.
This RFC patch adds support for parsing these two new blocks
and introduces new flags to signal the drivers if the
mode is 4:2:0'only or 4:2:0'able.
The reason this is still a RFC is because there is no
reference in kernel for this new sampling mode (specially in
AVI infoframe part), so, I was hoping to hear some feedback
first.
Tested in a HDMI 2.0 compliance scenario.

The plane hardware is used when the display scanout run into plane active
scanout, that means we can reuse the plane hardware resources on plane
non-active scanout.
Because resource share, There are some limit on share plane: one group
of share planes need use same zpos, can't not overlap, etc.
We assume share plane is a universal plane with some limit flags.
people who use the share plane need know the limit, should call the ioctl
DRM_CLIENT_CAP_SHARE_PLANES, and judge the planes limit before use it.
