Sorry forgot to include Ben.
Ben, any ideas?

The original algorithm doesn't perform very well in some cases, e.g.
When the source clock of the I2C controller is 66MHz, and the
requested rate is 100KHz, it gives
one by comparing the rate distances calculated by
two adjacent dividers.

One other better and cleaner approach to such inconsistency issue is
to have a timeout_ms field, and having i2c-gpio.c driver to convert
this
to jiffies using msec_to_jiffies() at run-time.
With what benefit
Hi, Jean
Thanks for your instruction.
Here is patch to modify some comments of i2c_master_send
i2c_master_recv, is this OK.
Where's the screaming things, dude?
Thanks

How about return error in i2c_master_send i2c_master_recv when count
is bigger than 64K, as suggested by Ben.
I think that's more preferable. Making the count parameter as u16,
though is going to generate a warning, yet that's usually ignored
by careless programmer, screaming out when this
11 matches
