TI's Industrial Communication Engine EVM is a low cost hardware mainly
developed for industrial communication type applications using serial
or Ethernet based interfaces. This platform features TI's AM3359 with
800MHz single core Cortex-A8 processor, 256MB DDR3, 64MB SPI flash,
8MB NOR Flash, mmc, usb, can, dual Ethernet ports.

For more information, look at HW user guide[1], Data manual[2].

Just add basic support for the moment.

Could you split this node on two leds@0 and led@1 and and move
all tpic2810 leds under leds0 and  all gpio leds under leds@1?

otherwise gpio leds will not work because tpic2810 is
configured as module and so leds-gpio will be deferred until
tpic2810 is loaded (but it can be never loaded ;)

led@x numeration has to be started from 0 for each leds@Y.

Hmm I get your point. I was always doing insmod of tpic2810 before doing
insmod of leds-gpio. Will fix it and repost.

Thanks and regards,
