This series includes patches 42-48 from "[PATCH v11 00/74] Add HDMI 2.0 support to DW HDMI QP TX" [1], which convert the VC4 HDMI driver to the common HDMI 2.0 scrambling infrastructure as a proof of concept for reusing the shared code. It adopts the shared TMDS character rate constants, switches to drm_hdmi_mode_needs_scrambling() and force_ctx(), fixes -EDEADLK handling, and replaces the driver-local scrambling implementation with the common SCDC scrambling helpers.
The infrastructure patches have been merged and there are no remaining dependencies, so the vc4 patches are now sent as a separate series, rebased on top of the latest drm-misc-next. Tested on a Raspberry Pi 5 Model B Rev 1.1 (BCM2712 D0).
