Here is a series to support the I2C core of the r7s72100 natively. It has been tested with a genmai board where an eeprom is connected. The series can be found here: git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux.git renesas/riic It is based on the latest r7s72100 topic branch from Simon and the latest patch series from Magnus. Note there is one issue with the current PFC driver which needs to be sorted out. Check patch 1/5 for details. I've addressed all comments from V1. See patches for details. Comments welcome.
