From 3237a31ae2775b0546a37a369df667075d7f6d87 Mon Sep 17 00:00:00 2001 From: Tim Harvey Date: Fri, 29 Mar 2024 08:09:40 -0700 Subject: [PATCH] arm64: dts: imx8mp-venice-gw73xx: add mac addr for eth1 The SoM used on this board does not bring down the pins for the QOS ethernet and instead offers the 2nd ethernet as a PCI GbE device. Set the alias as such and add the PCI bus topology for eth1 so that boot firmware can set the local-mac-address property. The eth1 device is behind a PCI switch: # lspci -n 00:00.0 0604: 16c3:abcd (rev 01) 01:00.0 0604: 12d8:2608 02:01.0 0604: 12d8:2608 02:02.0 0604: 12d8:2608 02:03.0 0604: 12d8:2608 02:04.0 0604: 12d8:2608 c0:00.0 0200: 1055:7430 (rev 11) # lspci -t -[0000:00]---00.0-[01-ff]----00.0-[02-fe]--+-01.0-[03-41]-- +-02.0-[42-80]-- +-03.0-[81-bf]-- \-04.0-[c0-fe]----00.0 Signed-off-by: Tim Harvey Signed-off-by: Shawn Guo --- .../dts/freescale/imx8mp-venice-gw73xx.dtsi | 36 +++++++++++++++++++ 1 file changed, 36 insertions(+) diff --git a/arch/arm64/boot/dts/freescale/imx8mp-venice-gw73xx.dtsi b/arch/arm64/boot/dts/freescale/imx8mp-venice-gw73xx.dtsi index d5c400b355af5..e63811b38c64f 100644 --- a/arch/arm64/boot/dts/freescale/imx8mp-venice-gw73xx.dtsi +++ b/arch/arm64/boot/dts/freescale/imx8mp-venice-gw73xx.dtsi @@ -8,6 +8,10 @@ #include / { + aliases { + ethernet1 = ð1; + }; + connector { compatible = "gpio-usb-b-connector", "usb-b-connector"; pinctrl-names = "default"; @@ -163,6 +167,38 @@ pinctrl-0 = <&pinctrl_pcie0>; reset-gpio = <&gpio4 29 GPIO_ACTIVE_LOW>; status = "okay"; + + pcie@0,0 { + reg = <0x0000 0 0 0 0>; + device_type = "pci"; + #address-cells = <3>; + #size-cells = <2>; + ranges; + + pcie@0,0 { + reg = <0x0000 0 0 0 0>; + device_type = "pci"; + #address-cells = <3>; + #size-cells = <2>; + ranges; + + pcie@4,0 { + reg = <0x2000 0 0 0 0>; + device_type = "pci"; + #address-cells = <3>; + #size-cells = <2>; + ranges; + + eth1: ethernet@0,0 { + reg = <0x0000 0 0 0 0>; + #address-cells = <3>; + #size-cells = <2>; + ranges; + local-mac-address = [00 00 00 00 00 00]; + }; + }; + }; + }; }; /* GPS */ -- 2.30.2
