SubjectRe: [PATCH-next] mfd/rtc: s5m: Do not allocate RTC I2C dummy and regmap for unsupported chipsets
> The rtc-s5m driver does not support all of S2M and S5M chipsets
> supported by main MFD sec-core driver. For such chipsets unsupported by
> rtc-s5m, the MFD sec-core driver initialized regmap with default config.
> This config in such cases wouldn't work at all.
> The main MFD sec-core driver shouldn't initialize regmap for child
> drivers which is not used by them and even not valid.
> Move the allocation of RTC I2C dummy device and initialization of RTC
> regmap from main MFD sec-core driver to the rtc-s5m driver. The rtc-s5m
> driver will use proper regmap config for supported devices.

It's a bit late in the cycle for this kind of change. Would you mind
re-sending after the v3.15 merge window please?
