Hi,

I did check the conversion against nxp/lpc/lpc3250-phy3250.dts, which
throws a message about the 'clocks' property.

That property is not documented in the original binding, and even though
it could be missing, I could not find any function to get a clock (i.e.
any form of clk_get()) in rtc-lpc32xx.c, which is the only file where
the compatible can be found.

Is therefore the property not useless in the dts? My apologies if I am
missing something here.

Thanks and best regards,
Javier Carrasco
