8 title: TI BQ25980 Flash Charger
11 - Andrew Davis <afd@ti.com>
14 The BQ25980, BQ25975, and BQ25960 are a series of flash chargers intended
15 for use in high-power density portable electronics. These inductorless
16 switching chargers can provide over 97% efficiency by making use of the
17 switched capacitor architecture.

32 ti,watchdog-timeout-ms:
34 Watchdog timer in milli seconds. 0 disables the watchdog.
38 enum: [ 0, 5000, 10000, 50000, 300000]
40 ti,sc-ovp-limit-microvolt:
42 Minimum input voltage limit in micro volts with a when the charger is in
43 switch cap mode. 100000 micro volt step.
48 ti,sc-ocp-limit-microamp:
50 Maximum input current limit in micro amps with a 100000 micro amp step.
54 ti,bypass-ovp-limit-microvolt:
56 Minimum input voltage limit in micro volts with a when the charger is in
57 switch cap mode. 50000 micro volt step.
61 ti,bypass-ocp-limit-microamp:
63 Maximum input current limit in micro amps with a 100000 micro amp step.
