Hi Dave,

If the pxa loses arbitration and switches into slave-receive mode or
if it is sitting on the line in slave-receive mode, the linux driver
has to read the data on the sda line.  Do you know if this is already
implemented in the driver?  I was under the impression that the
interface for master-receive would only receive data requested by the
command, not the data received while it was waiting to gain
arbitration.

Thanks,
Chander
