Summit smb350 battery charger
|
|
|
|
The smb350 charger supports stack-cell battery charging.
|
|
|
|
The smb350 interface is via I2C bus.
|
|
The i2c slave 7-bit address is programmable at manufacture.
|
|
|
|
Node required properties:
|
|
- compatible: Must be "summit,smb350-charger".
|
|
- reg: The device 7-bit I2C address.
|
|
- summit,stat-gpio gpio which smb350 STAT pin connects to.
|
|
- summit,chg-en-n-gpio gpio which control charging enable.
|
|
- summit,chg-susp-n-gpio gpio which control device shutdown
|
|
- summit,chg-current-ma charging current in milliamps.
|
|
- summit,term-current-ma charging termination current in milliamps.
|
|
valid values are 200/300/400/500/600/700.
|
|
A value of zero means no termination current.
|
|
|
|
Example:
|
|
i2c@f9967000 {
|
|
cell-index = <0>;
|
|
compatible = "qcom,i2c-qup";
|
|
reg = <0Xf9967000 0x1000>;
|
|
#address-cells = <1>;
|
|
#size-cells = <0>;
|
|
reg-names = "qup_phys_addr";
|
|
interrupts = <0 105 0>;
|
|
interrupt-names = "qup_err_intr";
|
|
qcom,i2c-bus-freq = <100000>;
|
|
qcom,i2c-src-freq = <24000000>;
|
