The following build warning is seen with W=1: Warning (unit_address_vs_reg): Node /soc/aips@60000000/ethernet@63fec000/ethernet-phy@0 has a unit name, but no reg property Fix this warning by adding reg property from such node and, consequently, includes a mdio node into the fec node, with the 'address-cells' and 'size-cells' to avoid these other following warnings: Warning (reg_format): "reg" property in /soc/aips@60000000/ethernet@63fec000/ethernet-phy@0 has invalid length (4 bytes) (#address-cells == 2, #size-cells == 1) Warning (avoid_default_addr_size): Relying on default #address-cells value for /soc/aips@60000000/ethernet@63fec000/ethernet-phy@0 Warning (avoid_default_addr_size): Relying on default #size-cells value for /soc/aips@60000000/ethernet@63fec000/ethernet-phy@0 Signed-off-by: Marco Franchi <marco.franchi@xxxxxxx> --- Change since v4: -pass the 'address-cells' and 'size-cells' values using a mdio node -change message log arch/arm/boot/dts/imx53-tx53.dtsi | 14 ++++++++++---- 1 file changed, 10 insertions(+), 4 deletions(-) diff --git a/arch/arm/boot/dts/imx53-tx53.dtsi b/arch/arm/boot/dts/imx53-tx53.dtsi index 71b58b6..a22e461 100644 --- a/arch/arm/boot/dts/imx53-tx53.dtsi +++ b/arch/arm/boot/dts/imx53-tx53.dtsi @@ -225,10 +225,16 @@ mac-address = [000000000000]; /* placeholder; will be overwritten by bootloader */ status = "okay"; - phy0: ethernet-phy@0 { - interrupt-parent = <&gpio2>; - interrupts = <4 IRQ_TYPE_EDGE_FALLING>; - device_type = "ethernet-phy"; + mdio { + #address-cells = <1>; + #size-cells = <0>; + + phy0: ethernet-phy@0 { + reg = <0>; + interrupt-parent = <&gpio2>; + interrupts = <4 IRQ_TYPE_EDGE_FALLING>; + device_type = "ethernet-phy"; + }; }; }; -- 2.7.4 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
