For the RTT as RTC driver rtc-at91sam9, the platform_device structure
is filled during SoC initialization. This will allow to convert this
RTC driver as a standard platform driver.

Can you make this more elaborate? I don't see from this or the code why
you don't just always register the RTT as "rtc-at91sam9". There seems to
be no driver for the "at91_rtt" in tree, so I don't know if there is
an out of tree driver binding to it.

Would it be possible to remove the compile time #if and the resetting
of the device name if both drivers bind to the rtc name and the other
rtt driver binds to both names?

because I see a quite some people use the rtt for something else

so I don't want to change on existing kernel
