1Motorola CPCAP PMIC battery charger binding
2
3Required properties:
4- compatible: Shall be "motorola,mapphone-cpcap-charger"
5- interrupts: Interrupt specifier for each name in interrupt-names
6- interrupt-names: Should contain the following entries:
7		   "chrg_det", "rvrs_chrg", "chrg_se1b", "se0conn",
8		   "rvrs_mode", "chrgcurr2", "chrgcurr1", "vbusvld",
9		   "battdetb"
10- io-channels: IIO ADC channel specifier for each name in io-channel-names
11- io-channel-names: Should contain the following entries:
12		    "battdetb", "battp", "vbus", "chg_isense", "batti"
13
14Optional properties:
15- mode-gpios: Optionally CPCAP charger can have a companion wireless
16	      charge controller that is controlled with two GPIOs
17	      that are active low.
