Re: [PATCH v2 10/11] staging: typec: fusb302: Hook up mux support using tcpc_gen_mux support

2017-09-25 Thread Peter Rosin
straction of what USB C muxes provide somewhere outside of the mux subsystem, and a bunch of implementations of that abstraction. One of those implementations could be to use "raw" muxes from the mux subsystem. Of course, this is not what this series is doing. Also, muxes that are not general purpose such as the ones added to the mux subsystem by this series could perhaps be repurposed for some other application, but since the interface implemented does not really obey the rules (the provided mux controller interacts with different sets of signals depending on the state) this will not be possible. These issues are what has caused me to do a lot of thinking and to sit silent, sorry about that, but I would like input from someone more experienced. If possible. But I'm not sure where to turn? As a crazy example, why is it not possible to hook up one signal pair from the USB C mux, not to DP, but instead to some I2C controller? Then, if done right, i2c-mux-gpmux could be hooked up with the relevant mux controller and use the signal pair for I2C, with the mux controller acting as a gate. So, maybe a bit crazy, but something like that is how I think it should work from the mux subsystem point of view. And while maybe crazy and while it might not be technically possible to do I2C over a USB C connector for some reason, I do think that whatever abstraction you come up with for USB C muxes, it has to deal with and broker requests from both the USB subsystem and whatever other subsystems deals with the alt pairs. Be it graphics for DP signals, or whatever. IIUC, the alt signals need not be graphics, and it would be sad to implement the USB C mux it in a way that makes it hard to use the alt pairs for something else. [maybe my understanding of USB C is just wrong] Cheers, Peter ___ devel mailing list de...@linuxdriverproject.org http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
