mfd: rk808: Add RK818 support
The RK818 chip is a Power Management IC (PMIC) for multimedia and handheld devices. It contains the following components: - Regulators - RTC - Clocking - Battery support Both RK808 and RK818 chips are using a similar register map, so we can reuse the RTC and Clocking functionality.
