It's not immediately obvious to me how exactly the interaction between your hid-sensor-hub driver, MFD and IIO is going to look like. If I understand it correctly, hid-sensor-hub will have to bind to all the supported devices in any case, and the distribution to other drivers that will be doing the processing will be done through callbacks, right? -- Jiri Kosina SUSE Labs -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
