Kernel-4.18.0-80.el8_lp8727_charger

Binding for TI/National Semiconductor LP8727 Charger

Required properties:

• compatible: “ti,lp8727”
• reg: I2C slave address 27h

Optional properties:

• interrupt-parent: interrupt controller node (see interrupt binding0)
• interrupts: interrupt specifier (see interrupt binding0)
• debounce-ms: interrupt debounce time. (u32)

AC and USB charging parameters

• charger-type: “ac” or “usb” (string)
• eoc-level: value of ‘enum lp8727_eoc_level’ (u8)
• charging-current: value of ‘enum lp8727_ichg’ (u8)

Example)

lp8727@27 {
compatible = “ti,lp8727”;
reg = <0x27>;

/* GPIO 134 is used for LP8728 interrupt pin */
interrupt-parent = <&gpio5>;     /* base = 128 */
interrupts = <6 0x2>;        /* offset = 6, falling edge type */

debounce-ms = <300>;

/* AC charger: 5% EOC and 500mA charging current */
ac {
    charger-type = "ac";
    eoc-level = /bits/ 8 <0>;
    charging-current = /bits/ 8 <4>;
};

/* USB charger: 10% EOC and 400mA charging current */
usb {
    charger-type = "usb";
    eoc-level = /bits/ 8 <1>;
    charging-current = /bits/ 8 <2>;
};
