Subject: Driver for pca9541 bus master selector
Date: Tue, 28 Sep 2010 07:33:02 -0700 [thread overview]
Message-ID: <20100928143302.GA7593@ericsson.com> (raw)
Hi all,
I am in the process of writing a driver for the pca9541 bus master selector.
I using the i2c multiplexer framework, which fits the requirements quite nicely.
If anyone happens to know about an existing driver for this chip, please let me know.
I would love to get some input for the arbitration mechanism needed to determine
if and when to switch bus ownership from one master to the other.
Thanks,
Guenter
