This is a well-structured 4-patch series adding SCDC (Status and Control Data Channel) link health information to the DRM connector debugfs. The series progresses logically: fix the return types, add HDMI 2.0 SCDC debugfs, wire it into bridge connectors, and extend for HDMI 2.1 fields. The implementation is clean and useful for debugging cable/link issues.
There is one significant correctness concern around **bitfield portability** — the `drm_scdc_status_flags` union overlays `bool` bitfields with a `u8` register value, but the bit ordering of bitfields is architecture-dependent and will be wrong on big-endian systems. There's also a design concern about conditionally reading status data only when update flags are set, which can produce confusing debugfs output showing stale or zero data.
Overall the series is in good shape and close to mergeable, with the bitfield portability being the main issue to address.
