A child driver can look DT up and reference the base information in MFD with or without compatible string. My idea was about easy-binding of DT without referencing parent node because the recent kernel support this infrastructure. I will add more information in DT to reuse the driver for the IP, and I will resubmit. -- 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
