My point is that it is also part of the PMIC so it may as well be
registers from the mfd driver which already registers a bunch of devices
instead of doing unusual stuff from the rtc driver.

mt6397_rtc->regmap is mt6397_chip->regmap anyway. You have the added
benefit that if the RTC driver probe fails for some reason, you may
still be able to probe the reset driver.

I don't tink there is any benefit having it as a child of the rtc
device.

Ok, that's fine.
