Thank you for your information.
We want to test 10-bit mode using the device.
So let me know the device information ?
Anyway, Now, kernel i2c-core is EXPERIMENTAL stage for 10-bit mode like
below.
(Documentation/i2c/ten-bit-addresses)
WARNING! The current 10 bit address support is EXPERIMENTAL. There
are several places in the code that will cause SEVERE PROBLEMS with
10 bit addresses, even though there is some basic handling and
hooks. Also,
almost no supported adapter handles the 10 bit addresses correctly.
As soon as a real 10 bit address device is spotted 'in the wild', we
can and will add proper support. Right now, 10 bit address devices
are defined by the I2C protocol, but we have never seen a single
device which supports them.
After kernel supports 10bit-mode formally, we will add the function to
i2c-eg20t again.
Thanks,
tomoya
