From 8226dbbf1d85be662ab6d427ca80c305cf0b719d Mon Sep 17 00:00:00 2001 From: Alexandru Gagniuc Date: Sun, 22 Dec 2013 21:30:21 -0500 Subject: cpu/allwinner/a10: Refactor and document pinmux API Include a function to multiplex more than one pin at a time. This is useful for peripherals that have the same function number for all their pins. Since we now have two functions for muxing pins, also document them.
