As promised here is my RFC to improve address spaces for I2C. This should give i2c seperate address spaces for standard clients, 10 bit clients, and our own slave clients. So, you can now have a 7 bit slave at 0x50 and a 10 bit slave at 0x050. Or, you can have a slave driver listening at some address and at the same time have a client driver talking to this address. Note that this is only the core support for that separation, I am still not sure if there is hardware being able talking to its own slave address, but we will see. This RFC and while I did some quick tests, it is not thoroughly tested. But I wanted to push it out before I leave the computer for the weekend. It still shows what path I chose to solve the problem. So, comments on that and further testing are more than welcome! BTW Andrey, I did not modify your patch and couldn't get the i2c-slave-eeprom driver to work with my Jetson TK1. Does this work for you?
