Glad my understanding is OK. :)

OK, great.
So just to summarize for Addy, I think you're being asked to spin one more time.
1. Update the patch description as per Uwe. Fix other typos pointed out by him.
2. Since you're spinning anyway, adjust "i2c" capitalization to "I2C".
3. If you agree with Uwe, rename spec_max_data_hold_ns to
spec_data_valid_ns. If not, we should debate in a followup patch.
4. If you think spec_data_hold_buffer_ns could be better represented
in another way (should this be i2c-sda-falling-time-ns"?), please do
so. If not, we should debate in a followup patch.
