commit 4c833c891ad02bfac8d6c2111a94befffd339014 Author: Suresh Rajashekara sureshraj@google.com Date: Mon Aug 15 16:18:11 2016 -0700
i2c/ww_ring: LED changes for Gale EVT3
Gale EVT3 has only one LED controller (earlier we had 2). Removing the support for the second controller and also the corresponding microcode. The color values used are the same as onHub (Arkham to be specific).
BUG=b:30890905 TEST=Move the device to different states manually by appropriate actions (like dev mode, rec mode etc) and observe the differnet colors. BRANCH=None
