Getting LEDs to work on custom AM3352 board

Hi All,

I have a custom board that’s based off the BeagleBone design (the version before the BBB). I have 4 LEDs wired up to GPIOs and believe they’re configured correctly in the board-am335xevm.c file. However after I’ve booted there are no entries under /sys/class/leds. Does anyone know what this indicates and how I should get these LEDs showing up under Linux?
