 4Description:
 5		What charging algorithm to use:
 6
 7		Standard:
 8			Fully charges battery at a standard rate.
 9		Adaptive:
10			Battery settings adaptively optimized based on
11			typical battery usage pattern.
12		Fast:
13			Battery charges over a shorter period.
14		Trickle:
15			Extends battery lifespan, intended for users who
16			primarily use their Chromebook while connected to AC.
17		Custom:
18			A low and high threshold percentage is specified.
19			Charging begins when level drops below
20			charge_control_start_threshold, and ceases when
21			level is above charge_control_end_threshold.
22		Long Life:
23			Customized charge rate for last longer battery life.
24			On Wilco device this mode is pre-configured in the factory
25			through EC's private PID. Swiching to a different mode will
26			be denied by Wilco EC when Long Life mode is enabled.
