I think the attached config might not be the right one. This issue
happens when the ts5500 support is selected (CONFIG_TS5500=y) but
the LED class (CONFIG_NEW_LEDS and CONFIG_LEDS_CLASS) is not.

Thanks for pointing this out.
The following patch below solves this issue. Is it ok, or should
I resend to whole board support patch?

Thanks,
Vivien
