Re: [U-Boot-Users] Proposal to add "ispeed" (I2C speed) command

This 'could' be usefull to speed up the i2c communication if there are more than one i2c devices with significant differences between the clock timing; ex. 27C32 (100kHz@3.3V) and LM75 (400kHz). Tolunay has spoken about like this. But right I see now reason to do so, too. U-Boot has to be a boot loader not a performant operator...

Do you think it is legal to clock the I2C bus at 400 kHz when there are devices on the bus that are spec'ed only for 100 kHz? I may be wrong, but such an idea sounds awfully risky to me.
