Both chips RK808 and RK818 are using a similar register map.

"Both RK808 ad RK818 chips"

So we can reuse the RTC and Clkout functionality.

Swap '.' for ','.

Why are you moving this to the header?

It is now part of the rk808 struct.

Why?

For me it seemed reasonable. My idea was to have only one chip variant
check.

I can move the rk808_reg_data struct back to the c file, check for the
chip variant within the probe function and initialize the proper
reg_data variable.
This would also apply to the mfd_cell variables.

'struct rk808' should only contain information you wish to share with
your subordinate/child devices.  Any data only used in the parent/MFD
driver should be declared, initialised and used only the latter.  No
need to export.
