It's usually helpful to keep a changelog here:

Please use correct grammar.

Although this error messages makes the comment above redundant.

[PATCH v5 4/7] 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.

[PATCH v5 5/7] clk: Kconfig: Name RK805 in Kconfig for COMMON_CLK_RK808

[Elaine Zhang]

The RK808 and RK805 PMICs are using a similar register map.
We can reuse the clk driver for the RK805 PMIC. So let's add
the RK805 in the Kconfig description.
