Motorola CPCAP PMIC battery charger binding
|
||||
|
||||
Required properties:
|
||||
- compatible: Shall be "motorola,mapphone-cpcap-charger"
|
||||
- interrupts: Interrupt specifier for each name in interrupt-names
|
||||
- interrupt-names: Should contain the following entries:
|
||||
"chrg_det", "rvrs_chrg", "chrg_se1b", "se0conn",
|
||||
"rvrs_mode", "chrgcurr2", "chrgcurr1", "vbusvld",
|
||||
"battdetb"
|
||||
- io-channels: IIO ADC channel specifier for each name in io-channel-names
|
||||
- io-channel-names: Should contain the following entries:
|
||||
"battdetb", "battp", "vbus", "chg_isense", "batti"
|
||||
|
||||
Optional properties:
|
||||
- mode-gpios: Optionally CPCAP charger can have a companion wireless
|
||||
charge controller that is controlled with two GPIOs
|
||||
that are active low.
|
||||
|
||||
Example:
|
||||
|
||||
cpcap_charger: charger {
|
||||
compatible = "motorola,mapphone-cpcap-charger";
|
||||
interrupts-extended = <
|
||||
&cpcap 13 0 &cpcap 12 0 &cpcap 29 0 &cpcap 28 0
|
||||
&cpcap 22 0 &cpcap 21 0 &cpcap 20 0 &cpcap 19 0
|
||||
&cpcap 54 0
|
||||
>;
|
||||
interrupt-names =
|
||||
"chrg_det", "rvrs_chrg", "chrg_se1b", "se0conn",
|
||||
"rvrs_mode", "chrgcurr2", "chrgcurr1", "vbusvld",
|
||||
"battdetb";
|
||||
mode-gpios = <&gpio3 29 GPIO_ACTIVE_LOW
|
||||
&gpio3 23 GPIO_ACTIVE_LOW>;
|
||||
io-channels = <&cpcap_adc 0 &cpcap_adc 1
|
||||
&cpcap_adc 2 &cpcap_adc 5
|
||||
&cpcap_adc 6>;
|
||||
io-channel-names = "battdetb", "battp",
|
||||
"vbus", "chg_isense",
|
||||
"batti";
|

};
