New Revision: 287419
URL: https://svnweb.freebsd.org/changeset/base/287419
Log:
Enable both i2c1 and i2c2. These devices are disabled in TI's DTS
so they were disabled during DTS transition. Though there are
no standard devices/drivers on them people might use iic(4) userland
interface to access these buses.
