1Binding for TI bq25890 Li-Ion Charger 2 3This driver will support the bq25892, the bq25896 and the bq25890. There are 4other ICs in the same family but those have not been tested. 5 6Required properties: 7- compatible: Should contain one of the following: 8 * "ti,bq25890" 9 * "ti,bq25892" 10 * "ti,bq25895" 11 * "ti,bq25896" 12- reg: integer, i2c address of the device. 13- interrupts: interrupt line; 14- ti,battery-regulation-voltage: integer, maximum charging voltage (in uV); 15- ti,charge-current: integer, maximum charging current (in uA); 16- ti,termination-current: integer, charge will be terminated when current in 17 constant-voltage phase drops below this value (in uA); 18- ti,precharge-current: integer, maximum charge current during precharge 19 phase (in uA); 20- ti,minimum-sys-voltage: integer, when battery is charging and it is below 21 minimum system voltage, the system will be regulated above 22 minimum-sys-voltage setting (in uV); 23- ti,boost-voltage: integer, VBUS voltage level in boost mode (in uV); 24- ti,boost-max-current: integer, maximum allowed current draw in boost mode 25 (in uA). 26 27Optional properties: 28- ti,boost-low-freq: boolean, if present boost mode frequency will be 500kHz, 29 otherwise 1.5MHz; 30- ti,use-ilim-pin: boolean, if present the ILIM resistor will be used and the 31 input current will be the lower between the resistor setting and the IINLIM 32 register setting; 33- ti,thermal-regulation-threshold: integer, temperature above which the charge 34 current is lowered, to avoid overheating (in degrees Celsius). If omitted, 35 the default setting will be used (120 degrees); 36- ti,ibatcomp-micro-ohms: integer, value of a resistor in series with 37 the battery; 38- ti,ibatcomp-clamp-microvolt: integer, maximum charging voltage adjustment due 39 to expected voltage drop on in-series resistor; 40 41Example: 42 43bq25890 { 44 compatible = "ti,bq25890"; 45 reg = <0x6a>; 46 47 interrupt-parent = <&gpio1>; 48 interrupts = <16 IRQ_TYPE_EDGE_FALLING>; 49 50 ti,battery-regulation-voltage = <4200000>; 51 ti,charge-current = <1000000>; 52 ti,termination-current = <50000>; 53 ti,precharge-current = <128000>; 54 ti,minimum-sys-voltage = <3600000>; 55 ti,boost-voltage = <5000000>; 56 ti,boost-max-current = <1000000>; 57 58 ti,use-ilim-pin; 59 ti,thermal-regulation-threshold = <120>; 60}; 61
