Why? The specs do not say anything about a minimum freq and fastest speed mentioned in the docs is 5Mhz (Ultra fast mode). * new binding "i2c-scl-clk-low-timeout-us" has a description which I do not understand. What is a waiting state? * new binding "no-detect" is broken. At the least, it should be named something like "bus-fully-described" and then the OS can decide to leave out auto-detection mechanisms. If you are interested in the latter, you can simply disable class based instantiation on the host controller. No need to describe this in DT. > Wolfram, you can take it or I can. Once we are done, I guess it is better if you take it.
