Subject: [PATCH 03/38] dt-bindings: power: supply: cpcap-charger: Convert to DT schema format
Convert the binding to DT schema format. I also added the missing bits
used by the only in-tree user and implemented in the driver.

-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"
