New Revision: 271100
URL: http://svnweb.freebsd.org/changeset/base/271100

Log:
  Implement the same public interface in imx51 and imx6 iomux; use the common
  header file for both.  Remove some unused code from imx51_iomux.  The iomux
  drivers are required, not optional, adjust the files.* entries accordingly.
