Subject[PATCH net v3 4/5] dt: cpsw: phy-handle, phy_id, and fixed-link are mutually exclusive
From: David Rivshin <>

The phy-handle, phy_id, and fixed-link properties are mutually exclusive,
and only one need be specified. Make this clear in the binding doc.

Also mark the phy_id property as deprecated, as phy-handle should be
used instead.

Signed-off-by: David Rivshin <>

Changes since v2 [1]:
- split from previous patch 2
- marked the phy_id property as deprecated [3]
- removed Rob Herring's Acked-by due to above change

Changes since v1 [2]:
- Rebased (no conflicts)
- Added Tested-by from Nicolas Chauvet
