New Revision: 248926
URL: http://svnweb.freebsd.org/changeset/base/248926
Log:
AR933x UART updates:
* Default clock is 25MHz;
* Remove the UART register macro here - it's not needed as we don't need
to "adjust" the register offset / spacing at all;
* Remove unused fields in the softc.
Tested:
* AP121
