Take drivers/spi/spi-imx.c for example, if you connect a NOR to it, you only need to add a NOR device node in the device tree. In the probe, it will call the m25p80.c to probe the NOR device. But if we connect other device to it. you should set another device node for it. I am not sure if your controller driver can works as the spi-imx.c thanks Huang Shijie -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
