Hi Dave and Daniel,
this is the forth pull request for drm-misc-next for what will become v5.8.
It's fairly small number of patches without major changes. There's one fix
to the UAPI headers, but it only affects comments.
Best regards

Runtime power management is essential for the Exynos Mixer driver
operation. It should be enabled before adding its DRM component, because
in some cases (when deferred probe takes place due to the IOMMU
availability) the DRM driver might be initialized directly from the
Mixer's component_add() call
This converts the Analogix ANX7814 bridge DT binding to yaml. Port
definitions and descriptions were expanded, apart from that it's a
direct translation from the original binding.

This series converts the DT binding documentation for the TI TFP410
DPI-to-DVI encoder to json-schema.
Some minor changes were made to two DTs in order to make them compliant
with the binding. These changes shouldn't have any functional effect.
This also fixes a minor bug in the ti-tfp410 driver

DRM_IOCTL_HANDLE_SET_LABEL lets you label buffers associated
with a handle, making it easier to debug issues in userspace
applications.
DRM_IOCTL_HANDLE_GET_LABEL lets you read the label associated
with a buffer.
Changes in v2:
- Hoist the IOCTL up into the drm_driver framework
Changes in v3:
Hi
I've been reworking these label'ing patches in conjunction
with their userspace usage that can be found here [1].
The intention is that these patches will be useful for driver
developers and application developers alike in conjuction with
something like the OpenGL Label'ing extension [2].
Chee
Set the default labeling helpers in order to be able
to label the buffers.

The R-Car DU supports inverting the polarity of the output pixel clock.
At the moment the driver hardcodes the clock polarity to drive signals
on the rising edge of the clock. Configure it instead based on the needs
of the display pipeline.

Replace iteration over encoders with iteration over connectors. This is
a bit more aligned with the atomic framework, but more importantly, the
change prepares for code that will need to access the connector.

The following series touches a lot of backlight things.
It starts by migrating users of of_find_backlight_by_node()
over to devm_of_find_backlight() to simplify code and to
use the preferred way to register backlight.
