In the current DSA switch driver API, only the udevice of the switch (belonging to UCLASS_DSA) is exposed, as well as an "int port" argument. So drivers do not have access to the udevice of individual ports (belonging to UCLASS_ETH), one of the reasons being that not all ports have an associated UCLASS_ETH udevice. However, all DSA ports have an OF node, and in some cases the driver needs a handle to it, for all ports including the CPU port. Example: the following Linux per-port device tree property: managed = "in-band-status"; states whether a port should operate with clause 37 in-band autoneg enabled or not. This patch exposes a function which can be called by individual drivers as needed. Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Reviewed-by: Ramon Fried <rfried.dev@gmail.com>
