Subject: [net-next,v4 0/2] ravb: Support describing the MDIO bus
Date: Mon, 25 Mar 2024 16:34:49 +0100	[thread overview]
Message-ID: <20240325153451.2366083-1-niklas.soderlund+renesas@ragnatech.se> (raw)

Hello,

This series adds support to the binding and driver of the Renesas
Ethernet AVB to described the MDIO bus. Currently the driver uses the OF
node of the device itself when registering the MDIO bus. This forces any
MDIO bus properties the MDIO core should react on to be set on the
device OF node. This is confusing and non of the MDIO bus properties are
described in the Ethernet AVB bindings.

Patch 1/2 extends the bindings with an optional mdio child-node to the
device that can be used to contain the MDIO bus settings. While patch
2/2 changes the driver to use this node (if present) when registering
the MDIO bus.

If the new optional mdio child-node is not present the driver fallback
to the old behavior and uses the device OF node like before. This change
is fully backward compatible with existing usage of the bindings.

For changelog see individual patches.
