Thanks again for responding. I don't have a clear idea about proper code organization concering this bus. The total number of possible bus devices is quite large, around 30. Half of them would take less than 10 extra lines to get support. The rest is more complicated. LP-8x4x has several features that would require a misc device anyway. It has a rotary switch which isn't an input device, because it produces no interrupts. The device also has a similar DIP switch. In addition, it acts as a kind of RS-485-port-to-multi-RS-232-ports logical bridge. It has a multiplexer which allows to talk to several serial modules which support a custom protocol designed for RS-485 using a RS-232 port. -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
