Hi Laxman, Stephen and me were discussing about the possible configuration of the i2c slave controller. The question here is if the slave and the master controller of the same port (or instance) can act in parallel. This is of particular interest when it comes to device tree representation. The Tegra3 TRM mentions a that the master can address its own slave for testing purposes. Also the i2c block diagram suggests that there are two controllers (for master and slave) connected to the same bus. If this is the case, master and slave mode is not exclusive, or in other words, the i2c master and slave need to share their resources. Another question is (because this would add a lot of code complexity) if we want to allow such a configuration at all.
