Recently I've been working on I2C device drivers for a number of devices on an embedded platform (specifically the Microchip line of A2Ds), and I'm planning to submit patches with my changes. However, my development is on an older system running Linux 3.10, and I'd really like to test my drivers with a more recent kernel. Getting a PC running a recent kernel release is straightforward, but I've found that there aren't a lot of great options for pluggable I2C busses on the PC (the USB Tiny is about the only one). That leads to my question - FTDI makes a number of USB interface chips with their Multi-Protocol Synchronous Serial Engine (MPSSE) component, which supports I2C. Kernel support for using the MPSSE as an I2C bus seems like it would provide a really convenient way to test I2C drivers on a PC, especially since the FTDI chips are easily available in multiple form factors from multiple vendors. Has anyone explored this? Are there obvious obstacles that I'm not thinking of? Would this be useful to anyone else? Thanks!
