I guess the question then becomes if that's an appropriate thing to do as part of a change set intended only to add DT bindings to an existing driver. It wouldn't remove much code since much of the bit-banging type code still needs to remain to support the MMIO mode. The chip does explicitly support a SPI type connection, but I'm unaware of any boards using it with a real SPI controller. -- Brandon Martin Mothic Technologies 317-565-1357 x7000 -- 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
