It has been..... uhhhh carry the two... longer than I want to admit
since I worked on a sparc. Would GPIO based LEDS make sense on a sparc
platform? Is sparc used much in the embedded world?

If yes, the of_register_platform_driver is just a nice wrapper. It
would be trivial to either change it to work on sparc, or add the
wrapper to the sparc includes.

We generally create the platform devices by hand for LED
devices on sparc64.

I'd CONFIG_POWERPC depend this thing for now.
