From 65c5b9d4310302c327231f8ba2bc54d034b34276 Mon Sep 17 00:00:00 2001 From: Aaron Durbin Date: Thu, 21 Aug 2014 14:50:36 -0500 Subject: tegra132: add enums for bus names Instead of requiring the mainboards to know the magic literals for the bus numbers provide an easier name to number to handle all the weird ordering. BUG=chrome-os-partner:31106 BRANCH=None TEST=Built and booted on ryu.
