Copied from the jz4740 devicetree and trimmed to 5 timers, which

It seems more reasonable to use "reg = <0x40 0x80>" since the
X1000 has only 5 PWM channels.

One line is now allowed to hold at most 100 characters,
so it is possible to use only one line like:

        clock-names = "timer0", "timer1", "timer2", "timer3", "timer4";

to reduce the number of lines in the dtsi file.


Thanks and best regards!
