Measurements on i.MX1 and i.MX53 have shown that the divider values
in the datasheets are wrong. the values from first, third and fourth
column were all measured to be 8 higher than in the datasheet. It
should be safe to assume that the SoCs between i.MX1 and i.MX53 behave
the same as the i2c unit is unchanged since the i.MX1.

We may need to check with IC guys? Or you've done?

I don't have contact to the IC guys. Could you do this? I'd be
interested in the results.

Sure, but it may be slow, as you know, many people are in summer break.

Thanks. It can take longer, the resulting frequencies are all too low,
so we are on the safe side.

You mean safe before the patch is applied, not after. Right?
