Author: manu Date: Thu Nov 29 19:06:05 2018 New Revision: 341254 URL: https://svnweb.freebsd.org/changeset/base/341254 Log: extres: clk: Fix clk_set_assigned ofw_bus_parse_xref_list_get_length doesn't returns the number of elements, fix this. While here when setting the clock to the assigned freqeuncy, allow the clock driver to round down or up the frequency as sometimes the exact frequency cannot be obtain.
