[PATCH v1 3/4] regulator: rk808: Add regulator driver for RK805

[Elaine Zhang]

Add support for the rk805 regulator. The regulator module consists
of 4 DCDCs, 3 LDOs.

The output voltages are configurable and are meant to supply power
to the main processor and other components.

[PATCH v1 4/4] mfd: rk808: Add RK805 support

[Elaine Zhang]

The RK805 chip is a Power Management IC (PMIC) for multimedia and handheld
devices. It contains the following components:

    - Regulators
    - RTC
    - Clocking

Both RK808 and RK805 chips are using a similar register map,
so we can reuse the RTC and Clocking functionality.

Re: [PATCH v1 0/4] rk808: Add RK805 support

[Wadim Egorov]

Hi Elaine,

you should also add the RK805 to the device tree bindings documentation in

Documentation/devicetree/bindings/mfd/rk808.txt

Regards,
Wadim
