Cover letter [PATCH v2 0/2] New driver: i2c_imc (Intel LGA2011 iMC SMBUS)
Intel's LGA2011 chips (Core i7 Extreme and Xeon E5) have two SMBUS controllers per package, addressing up to 16 DIMM slots per package. This is a driver for those SMBUS channels.
The first patch is a minor change to the i2c core to make it work better with extremely limited hardware like this. The second patch is the driver.
Changes from the RFC / v1: Work around an erratum that gave random incorrect reads on multi-socket systems.
