[PATCH v8 0/2] drm_bridge: Add HDCP support

[Fei Shao]

Hi Doug,

This is a refreshed series to add HDCP support to DRM bridge.

This v8 revision is based on [v7] and rebased on top of next-20250731.
Note that v7 includes 3 patches, while v8 has only 2. The rationale for
this change is provided below.

In this series:
- Patch 1 registers the content protection property to the bridge
  connector if a bridge supports HDCP.
- Patch 2 sets the HDCP bit in the ANX7625 bridge driver.

Both Patch 1 and Patch 2 were previously reviewed and acked (sort of,
see [ref]). The Reviewed-by tags are carried over as there are no major
changes in v8, except for the rebase.

The third patch from v7, which was specific to the ite-it6505 driver,
isn't included in this series. Discussion on that patch had stalled, and
it was later reverted in the downstream ChromeOS tree, meaning no
manufactured Chromebook devices in the field currently use it.

As a result, I think we can only focus on the first two patches which
have already undergone review.

Please take a look. Thank you.
