If so, you can just pass the standard clock phandle. I know we don't yet have the DT clocks merged, but Tero just posted another revision of those. > > +- tcxoclock: the internal WLAN TCXO clock frequency (required for > > + WiLink7 not used for WiLink6 and WiLink8).

If we can use the standard bindings, it might be worth waiting until we have the DT clocks available as we have the pdata workaround merged anyways. That's because then we don't need to support the custom binding later on ;) Regards, Tony -- To unsubscribe from this list: send the line "unsubscribe linux-doc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
