dt-bindings: battery: add new battery parameters
Add:
- trickle-charge-current-microamp:
Some chargers have 3 charging stages. First one when battery is almost
empty is often called as trickle-charge. Last state when battery has been
"woken up" is usually called as fast-charge. In addition to this some
chargers have a 'middle state' which ROHM BD99954 data-sheet describes as
pre-charge. Some batteries can benefit from this 3-phase charging
[citation needed].
Introduce trickle-charge-current-microamp so that batteries can give
charging current limit for all three states.
- precharge-upper-limit-microvolt:
When battery voltage has reached certain limit we change from
trickle-charge to next charging state (pre-charge for BD99954). Allow
battery to specify this limit.
- re-charge-voltage-microvolt:
Allow giving a battery specific voltage limit for chargers which can
automatically re-start charging when battery has discharghed down to
this limit.
- over-voltage-threshold-microvolt
Allow specifying voltage threshold after which the battery is assumed to
be faulty.
