This patch adds the bindings for the MSM DisplayPort HDCP registers
which are required to write the HDCP key into the display controller as
well as the registers to enable HDCP authentication/key
exchange/encryption.

encoder->commit() was being misused because there were some global
resources which needed to be tweaked in encoder->enable() which were not
accessible in dpu_encoder.c. That is no longer true and the redirect
serves no purpose any longer. So remove the indirection.
From: Sean Paul
A couple more useless checks to remove in dpu_encoder.

Now that all of the HDCP 1.x logic has been migrated to the central HDCP
helpers, use it in the i915 driver.
The majority of the driver code for HDCP 1.x will live in intel_hdcp.c,
however there are a few helper hooks which are connector-specific and
need to be partially or

The shim functions return error codes, but they are discarded in
intel_hdcp.c. This patch plumbs the return codes through so they are
properly handled.

Stick all of the setup for HDCP into a dedicated function. No functional
change, but this will facilitate moving HDCP logic into helpers.

This patch expands upon the HDCP helper library to manage HDCP
enable, disable, and check.
Previous to this patch, the majority of the state management and sink
interaction is tucked inside the Intel driver with the understanding
that once a new platform supported HDCP we could

This patch updates the connector's property value in 2 cases which were
previously missed:
1- Content type changes. The value should revert back to DESIRED from
ENABLED in case the driver must re-authenticate the link due to the
new content type.
2- Userspace sets value

Instead of forcing a modeset in the hdcp atomic check, simply return
true if the content protection value is changing and let the driver
decide whether a modeset is required or not.

This patch moves the hdcp atomic check from i915 to drm_hdcp so other
drivers can use it. No functional changes, just cleaned up some of the
code when moving it over.

Hello again,
This is the second version of the HDCP helper patchset. See version 1
