Author: mmel Date: Sun Jul 12 07:59:15 2020 New Revision: 363123 URL: https://svnweb.freebsd.org/changeset/base/363123 Log: Reverse the processing order of assigned clocks property. Linux processes these clocks in reverse order and some DT relies on this fact. For example, the frequency setting for a given PLL is the last in the list, preceded by the frequency setting of its following divider or so...
