H A D | rzfive-smarc-som.dtsi | 7a98d75c Wed Jul 12 03:14:44 CDT 2023 Conor Dooley <conor.dooley@microchip.com> riscv: dts: renesas: Clean up dtbs_check W=1 warning due to empty phy node
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", "renesas,rzg2l-gbeth"; /* snip */ #address-cells = <1>; #size-cells = <0>; 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", "renesas,rzg2l-gbeth"; /* snip */ #address-cells = <1>; #size-cells = <0>; status = "disabled"; };
