0e2f733add dma-buf: make dma_fence structure a bit smaller v2 
We clear the callback list on kref_put so that by the time we
release the fence it is unused. No one should be adding to the cb_list
that they don't themselves hold a reference for.

This small change is actually making the structure 16% smaller.

v2: add the comment to the code as well.

This includes likely the first grayscale panel supported.

These panels will be used with the PL11x DRM driver.

43f847d0b9 drm/pl111: Support grayscale 
Migrating the TI nspire calculators to use the PL111 driver for
framebuffer requires grayscale support for the elder panel
which uses 8bit grayscale only.

DRM does not support 8bit grayscale framebuffers in memory,
but by defining the bus format to be MEDIA_BUS_FMT_Y8_1X8 we
can get the hardware to turn on a grayscaling feature and
convert the RGB framebuffer to grayscale for us.

013b651013 drm/panfrost: Add madvise and shrinker support 
Add support for madvise and a shrinker similar to other drivers. This
allows userspace to mark BOs which can be freed when there is memory
pressure.

Unlike other implementations, we don't depend on struct_mutex. The
driver maintains a list of BOs which can be freed when the shrinker
is called. Access to the list is serialized with the shrinker_lock.

DRM API for generating uevent for a status changes of connector's
property.

This uevent will have following details related to the status change:

  HOTPLUG=1, CONNECTOR=<connector_id> and PROPERTY=<property_id>

Pekka have completed the Weston DRM-backend review in
https://gitlab.freedesktop.org/wayland/weston/merge_requests/48
and the UAPI for HDCP 2.2 looks good.

The userspace is accepted in Weston.

7672dbba85 drm: Add Content protection type property 
This patch adds a DRM ENUM property to the selected connectors.
This property is used for mentioning the protected content's type
from userspace to kernel HDCP authentication.

Type of the stream is decided by the protected content providers.
Type 0 content can be rendered on any HDCP protected display wires.
But Type 1 content can be rendered only on HDCP2.2 protected paths.

So when a userspace sets this property to Type 1 and starts the HDCP
enable, kernel will honour it only if HDCP2.2 authentication is through
for type 1. Else HDCP enable will be failed.

Pekka have completed the Weston DRM-backend review in
https://gitlab.freedesktop.org/wayland/weston/merge_requests/48
and the UAPI for HDCP 2.2 looks good.

The userspace is accepted in Weston.
