This initial device tree describes CPU, interrupts and UART on the chip
and is able to boot into basic kernel with only UART. Cache information
is omitted for now as there is no precise documentation. Support for
other features will be added later.

Please use "xin24m: clock-xin24m { ... }" instead, because that follows
the recently established revised pattern for clock names.  We should 
have
come consistency in the new SoC dtsi additions.

It's a careless typo, sorry for the noise. Will be fixed in next version.
