Then should this mux be registered in the CCF so you can use the usual

Hello Alexandre,
In hardware, these clock muxes and divisors are part of the RTC module
itself and not external. Therefore, I would say no.
This is irrelevant, if this is a clock mux, it must be in the CCF, just
as when the RTC has a clock output.
I understand your point, but taking into account the fact that FIRC
clock should be used in most scenarios, would it be acceptable to not
export this 'clksel' property in the devicetree bindings and simply use
the FIRC clock by default in the RTC driver ?
At least for this patchset, in order to ease the review process. If
configurable clock source support would want to be enabled and exported
via bindings for this S32G2/S32G3 RTC driver, then CCF registration for
this clk mux could be added in future patches.
