Subject: [PATCH v2 0/4] can: Add new binding to limit bit rate used
Date: Mon, 24 Jul 2017 18:05:17 -0500 [thread overview]
Message-ID: <20170724230521.1436-1-fcooper@ti.com> (raw)
Add a new generic binding that CAN drivers can use to specify the max
arbitration and data bit rate supported by a transceiver. This is
useful since in some instances the maximum speeds may be limited by
the transceiver used. However, transceivers may not provide a means
to determine this limitation at runtime. Therefore, create a new binding
that mimics "fixed-link" that allows a user to hardcode the max speeds
that can be used.
Also add support for this new binding in the MCAN driver.
Note this is an optional subnode so even if a driver adds support for
parsing fixed-transceiver the user does not have to define it in their
device tree.
Version 2 changes:
Rename function
Define proper variable default
Drop unit address
Move check to changelink function
Reword commit message
Reword documentation
