Based on the board property switch the source from internal

rtcwake to work in low power modes.
I think this is better handled based on the compatible string
in the device driver rather than introducing a custom dts
property for it. You can just set the quirk flag in the driver
probe based on the compatible.
Why not use the clocks property? Then you can pass an external clock. If
it is present you can even get its rate if this is needed at some point
in the future. You could also disable it when going to suspend.
Actually, that was already my suggestion back in april:

(Please Cc: the rtc mailing list for RTC related patches so that they
get picked up by patchwork).
Hi Alexandre,
This is a special one where in the enable bit is present in the rtc
register space and not in the prcm register space. Since there was a
concern on the external clock not being present i added a board dts flag.

Keerthy
