"ti,tca6507" would be more typical.

You probably want to mention which binding document defines the valid
values for that property; ../gpio/led.txt I think.

I wonder if we need to think about representing the blinking/fading/...
capabilities of the chip too? Should that be encoded into the DT, or
should it be controlled at run-time via some LED subsystem?
