Yeah, it is possible using the of_hwspin_lock_get_base_id function added in Patch8, once we convert the phandle to a device node. The platform implementations would be using this function during the registration phase to register the base id, and we have to do the DT parse/lookup again in the core. regards Suman -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
