The branch stable/12 has been updated by mw: URL: https://cgit.FreeBSD.org/src/commit/?id=cd1393dfe7189c21739b4581b9cbdda680c54f59 commit cd1393dfe7189c21739b4581b9cbdda680c54f59 Author: Marcin Wojtas <mw@FreeBSD.org> AuthorDate: 2021-01-26 10:49:35 +0000 Commit: Marcin Wojtas <mw@FreeBSD.org> CommitDate: 2021-02-02 12:27:38 +0000 marvell: ap806_clock: add missing frequency modes In the driver init routine the CPU clock frequency value is obtained from a dedicated register. Until now only part of the values were handled by the mv_ap806_clock driver. Fix that by adding missing cases.
