Subject: [PATCH RFT 0/2] i2c: rcar: improve Gen3 support

Here is the second series paving the way for Gen4 support. This time we
properly apply the Gen3 specific features. See the patch comments for
further information. This has been tested on a Renesas Falcon board with
a R-Car V3U SoC at various bus speeds. Because the calculation formulas
are crucial, testing on board farms would be much appreciated!

Thanks and happy hacking!
