2362306a36Sopenharmony_ciOptional properties:
2462306a36Sopenharmony_ci
2562306a36Sopenharmony_ciThe abx804 and abx805 have a trickle charger that is able to charge the
2662306a36Sopenharmony_ciconnected battery or supercap. Both the following properties have to be defined
2762306a36Sopenharmony_ciand valid to enable charging:
2862306a36Sopenharmony_ci
2962306a36Sopenharmony_ci - "abracon,tc-diode": should be "standard" (0.6V) or "schottky" (0.3V)
3062306a36Sopenharmony_ci - "abracon,tc-resistor": should be <0>, <3>, <6> or <11>. 0 disables the output
3162306a36Sopenharmony_ci                          resistor, the other values are in kOhm.
