Subject: [PATCH 3/4] dt-bindings: net: can: Document transceiver implementation as phy

From: Faiz Abbas <faiz_abbas@...com>

Some transceivers need a configuration step (for example, pulling the
standby or enable lines) for them to start sending messages. The
transceiver can be implemented as a phy with the configuration done in the
phy driver. The bit rate limitation can the be obtained by the driver using
the phy node.

Document the above implementation in the bosch mcan bindings
