Author: mmel Date: Thu Jul 30 14:45:05 2020 New Revision: 363700 URL: https://svnweb.freebsd.org/changeset/base/363700
Log: Move Ti AM335x to dev/extres/clk framework. Re-implement clocks for these SoC by using now standard extres/clk framework. This is necessary for future expansion of these. The new implementation is (due to the size of the patch) only the initial (minimum) version. It will be updated/expanded with a subsequent set of particular patches. This patch is also not tested on OMAP4 based boards (BeagleBone), so all possible issues should be (and will be) fixed by ASAP once identified.
