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.
