The `mrvl,i2c-fast-mode` should be IMO completely removed and whether it is enabled should be decided by the value of `clock-frequency`. BTW there are clock generating registers in A3720 I2C controller that can generate 100 kHz even in fast-mode. The driver does not use them, though, it leaves them to their default values, which for normal mode generate ~96 kHz and for fast mode ~258 kHz. Maybe we should implement configuring these registers and make the driver choose normal-mode / fast-mode / high-speed mode depending on `clock-frequency` ? Marek
