- RK816, RK817 and RK818 Power Management chips.
+ If you say yes here you get support for the RK801, RK805, RK808,
+ RK809, RK816, RK817 and RK818 Power Management chips.
This driver provides common support for accessing the device
through I2C interface. The device supports multiple sub-devices
including interrupts, RTC, LDO & DCDC regulators, and onkey.
