Add bindings for Renesas R-Car Ethernet TSN End-station IP. The RTSN device provides Ethernet network. Signed-off-by: Niklas Söderlund <niklas.soderlund+renesas@ragnatech.se> --- * Changes since v1 - Update patch subject, was "dt-bindings: net: renesas,ethertsn: Add bindings for Ethernet TSN". - Add top-level $ref to ethernet-controller.yaml. - Rework compatible node to have a fallback, renesas,rcar-gen4-ethertsn. - Change compatible value to match renesas style, was renesas,ethertsn-r8a779g0. - Change interrupt names from "tx_data", "rx_data" to "tx", "rx". - Add missing unevaluatedProperties. - Use the generic properties for internal delay tx-internal-delay-ps and rx-internal-delay-ps instead of vendor specific ones. --- .../bindings/net/renesas,ethertsn.yaml | 133 ++++++++++++++++++ 1 file changed, 133 insertions(+) create mode 100644 Documentation/devicetree/bindings/net/renesas,ethertsn.yaml
