This is a platform-specific bus (PXA27x). Should it go into pxa27x.dtsi rather than machine dts? > In case there is a driver for the extbus node, I would not make it > "simple-bus" but instead add a separate compatible string to match > the driver, and let that driver call of_platform_populate > to probe the children after the bus is set up. There seems to be none at the moment. However, some machines need to setup these partitions as a part of their initialization. So complete migration to DT will require this driver. In LP-8x4x case everything is setup by the bootloader. So "simple-bus" works for me. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
