[RFC PATCH 0/7] i2c: sh_mobile: support per-SoC frequency calculation

The current calculation for I2C bus speeds does not match the datasheet and is, in deed, a little too fast for 100kHz settings (~107kHz have been measured). This series implements a second calculation according to the datasheet. In order to not cause regressions on the various old SoCs, using
