2013-02-10i2c: Adding support for Intel iSMT SMBus 2.0 host controllerNeil Horman
The iSMT (Intel SMBus Message Transport) supports multi-master I2C/SMBus, as well as IPMI. It's operation is DMA-based and utilizes descriptors to initiate transactions on the bus. The iSMT hardware can act as both a master and a target, although this driver only supports being a master.
