power: supply: PCHG: Peripheral device charger
This patch adds a driver for PCHG (Peripheral CHarGer). PCHG is a
framework managing power supplies for peripheral devices.
This driver creates a sysfs node for each peripheral charge port:
/sys/class/power_supply/peripheral<n>
where <n> is the index of a charge port.
For example, when a stylus is connected to a NFC/WLC port, the node
returns:
/sys/class/power_supply/peripheral0/
capacity=50
charge_type=Standard
scope=Device
status=Charging
type=Battery
