Hi, I was wondering if the buffer in an i2c_msg, passed to i2c_transfer must be dma-able i.e. dynamically allocated, like for USB?
The reason why I'm asking is because the e.g. the i2c_robotfuzz_osif usb-to- i2c adapter passes the incoming data directly to a usb_control_msg which of course expects the buffer to be dma-able. So the question is - does the user of i2c_transfer have to provide a dma-able buffer, or is the bus driver (like the robotfuzz one) expected to convert incoming buffer into a dma-able buffer?
