pwr_avg provides an average voltage, current, and power over the last 1 minute. It's up to the battery drivers to implement this functionality. This change allows us to have better power tracking while minimizing the power impact on the EC, because - the pwr_avg command only needs to be called once every minute, and is short, thus less expensive to parse on ECs without a UART buffer - the work done to keep the avg is partially done by the batteries already and it's just a question of retrieving it. undefined on wheatley since no power debugging planned on that board. usage: > pwr_avg mv = 7153 ma = -605 mw = -4327 BUG=chromium:752320 BRANCH=None TEST=make buildall -j Change-Id: Id1a3479d277aedf90dfa965afb4ee9136654b1cf Signed-off-by: Ruben Rodriguez Buchillon <coconutruben@chromium.org> Reviewed-on: https://chromium-review.googlesource.com/823884 Reviewed-by: Vincent Palatin <vpalatin@chromium.org>
