commit d21947ea0d6f5e6bc178a442de21fe3204a5e9ef Author: Aaron Durbin adurbin@chromium.org Date: Tue Aug 4 14:02:54 2015 -0500
skylake: fill out gen_pmcon_* bitfields
Open coding bitfields is really annoying as no one knows what they are unless you have a doc in front of you. Fill in the bitfields for the GEN_PMCON_A and GEN_PMCON_B registers.
BUG=chrome-os-partner:43522 BRANCH=None TEST=Built and booted glados.
