| Subject: [PATCH 0436/1795] dt-bindings: net: renesas-ravb: Make stream buffer |
| optional |
| |
| The Stream Buffer for EtherAVB-IF (STBE) is an optional component, and |
| is not present on all SoCs. |
| |
| Document this in the DT bindings, including a list of SoCs that do have |
| it. |

| Fixes: 785ec87483d1e24a ("ravb: document R8A77970 bindings") |
| Fixes: f231c4178a655b09 ("dt-bindings: net: renesas-ravb: Add support for R8A77995 RAVB") |
