Re: Linux I2C driver support for intel QM57 chipset
Intel has usually been pretty good at adding support for their products to the Linux kernel prior to them releasing their product. Since QM57 was released back in January, it should be fully supported by Linux, especially by any kernel that's been released since.
I2C (or SMBus) support in Linux is divided up into two portions. First being the I2C controller, and then second by each device that is connected to the I2C network.
