Should be <0xa>. + +From OS view the device is basically an i2c-mux used to communicate with up to +four smart battery devices at address 0xb. The driver actually implements this +behaviour. So standard i2c-mux nodes can be used to register up to four slave +batteries. Channels will be numerated starting from 1 to 4. + +Example: + +batman@0a { + compatible = "lltc,ltc1760"; + reg = <0x0a>; + #address-cells = <1>; + #size-cells = <0>; + + i2c@1 { + #address-cells = <1>; + #size-cells = <0>; + reg = <1>; + + battery@0b { + compatible = "ti,bq2060", "sbs,sbs-battery"; + reg = <0x0b>; + }; + }; + + i2c@2 { + #address-cells = <1>; + #size-cells = <0>; + reg = <2>; + + battery@0b { + compatible = "ti,bq2060", "sbs,sbs-battery"; + reg = <0x0b>; + }; + }; + + i2c@3 { + #address-cells = <1>; + #size-cells = <0>; + reg = <3>; + + battery@0b { + compatible = "ti,bq2060", "sbs,sbs-battery"; + reg = <0x0b>; + }; + }; +}; --
