pf1550,thermistor-monitoring-mode

string

Thermistor monitoring mode.
Refer to ThrmCfg register description and Table 2 for details.

This property is required.

Legal values: 'disabled', 'thermistor', 'JEITA-1', 'JEITA-2'

pf1550,int-gpios

phandle-array

Interrupt pin

This property is required.

pf1550,led-behaviour

string

Behaviour for charger LED.

This property is required.

Legal values: 'on-in-charging-flash-in-fault', 'flash-in-charging-on-in-fault', 'manual-off'

device-chemistry

string

This describes the chemical technology of the battery. The "lithium-ion" value is a blanket type for all lithium-ion batteries. If the specific chemistry is unknown, this value can be used instead of the precise "lithium-ion-X" options.

Legal values: 'nickel-cadmium', 'nickel-metal-hydride', 'lithium-ion', 'lithium-ion-polymer', 'lithium-ion-iron-phosphate', 'lithium-ion-manganese-oxide'

ocv-capacity-table-0

array

An array providing the open circuit voltage (OCV) , which is used to look
up battery capacity according to current OCV value. The OCV unit is
microvolts.

Unlike the linux equivalent this array is required to be 11 elements
long, representing the voltages for 0-100% charge in 10% steps.

charge-full-design-microamp-hours

int

battery design capacity

re-charge-voltage-microvolt

int

limit to automatically start charging again

precharge-current-microamp

int

current for pre-charge phase

charge-term-current-microamp

int

current for charge termination phase
