This series enables the driver to use it. It is based on the series "i2c: clock calculation cleanups for Renesas devices" and "i2c: rcar: improve Gen3 support". A branch for testing can be found here: git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux.git renesas/i2c/fmplus-experimental Shimoda-san: Maybe the BSP team and/or the test team might want to try this branch? Looking forward to comments and test reports etc. Happy hacking!
