dtbs_check w/ W=1 complains: Warning (unit_address_vs_reg): /soc/ethernet@11c20000/ethernet-phy@7: node has a unit name, but no reg or ranges property Warning (avoid_unnecessary_addr_size): /soc/ethernet@11c20000: unnecessary #address-cells/#size-cells without "ranges" or child "reg" property The ethernet@11c20000 node is guarded by an `#if (!SW_ET0_EN_N)` in rzg2ul-smarc-som.dtsi, where the phy child node is added. In rzfive-smarc-som.dtsi, the ethernet node is marked disabled & the interrupt properties are deleted from the phy child node. As a result, the produced dts looks like: ethernet@11c20000 { compatible = "renesas,r9a07g043-gbeth\0renesas,rzg2l-gbeth"; /* snip */ #address-cells = <0x01>; #size-cells = <0x00>; status = "disabled"; ethernet-phy@7 { }; }; Adding a corresponding `#if (!SW_ET0_EN_N)` around the node in rzfive-smarc-som.dtsi avoids the complaint, as the empty child node is not added: ethernet@11c20000 { compatible = "renesas,r9a07g043-gbeth\0renesas,rzg2l-gbeth"; /* snip */ #address-cells = <0x01>; #size-cells = <0x00>; status = "disabled"; }; Signed-off-by: Conor Dooley <conor.dooley@microchip.com> --- CC: Geert Uytterhoeven <geert+renesas@glider.be> CC: Magnus Damm <magnus.damm@gmail.com> CC: Prabhakar Mahadev Lad <prabhakar.mahadev-lad.rj@bp.renesas.com> CC: Rob Herring <robh+dt@kernel.org> CC: Krzysztof Kozlowski <krzysztof.kozlowski+dt@linaro.org> CC: Conor Dooley <conor+dt@kernel.org> CC: linux-renesas-soc@vger.kernel.org CC: devicetree@vger.kernel.org CC: linux-riscv@lists.infradead.org CC: linux-kernel@vger.kernel.org --- arch/riscv/boot/dts/renesas/rzfive-smarc-som.dtsi | 2 ++ 1 file changed, 2 insertions(+)
