Author: loos Date: Sun Aug 30 22:38:06 2015 New Revision: 287315 URL: https://svnweb.freebsd.org/changeset/base/287315 Log: The vendor's DTS for Allwinner A20 uses a different way to map the gpio pins, they specify the bank and the pin in two separated cells. This allow the use of vendor's DTS definitions by adding a gpio map routine that copes with that.
