Sorry I missed addressing this comment. I am not adding a config option but I am re-using the CONFIG option that already exists. I did not want to define the GPIO number twice. This CONFIG option is also used in the ehci-omap.c file. Dan > >> #endif > Best regards, > Marek Vasut

I can't say I'm happy about it being called CONFIG_ tho, maybe this can be fixed (in later patch). Best regards, Marek Vasut
