[PATCH 2/2] MAINTAINERS: update PTP maintainer entries after directory split

Wen Gu
2026-03-18T07:33:40Z

Update MAINTAINERS to match the new drivers/ptp/ directory layout after
splitting emulated and IEEE 1588 network-oriented drivers into
subdirectories.

Adjust file patterns and per-driver entries to point to their new
locations, and add a dedicated MAINTAINERS entry for the emulated PTP
clock drivers.
