If you are in this * situation, you should either update your bootloader (preferred * solution) or the below Device Tree should be adjusted. */ /dts-v1/; #include #include #include "armada-370.dtsi" / { model = "Marvell Armada 370 Reference Design"; compatible = "marvell,a370-rd", "marvell,armada370", "marvell,armada-370-xp"; chosen { stdout-path = "serial0:115200n8"; }; memory@0 { device_type = "memory"; reg = <0x00000000 0x20000000>; /* 512 MB */ }; soc { ranges = ; internal-regs { serial@12000 { status = "okay"; }; sata@a0000 { nr-ports = <2>; status = "okay"; }; ethernet@70000 { status = "okay"; phy = <&phy0>; phy-mode = "sgmii"; }; ethernet@74000 { pinctrl-0 = <&ge1_rgmii_pins>; pinctrl-names = "default"; status = "okay"; phy-mode = "rgmii-id"; fixed-link { speed = <1000>; full-duplex; }; }; mvsdio@d4000 { pinctrl-0 = <&sdio_pins1>; pinctrl-names = "default"; status = "okay"; /* No CD or WP GPIOs */ broken-cd; }; usb@50000 { status = "okay"; }; usb@51000 { status = "okay"; }; gpio-keys { compatible = "gpio-keys"; #address-cells = <1>; #size-cells = <0>; button { label = "Software Button"; linux,code = ; gpios = <&gpio0 6 GPIO_ACTIVE_LOW>; }; }; gpio-fan { compatible = "gpio-fan"; gpios = <&gpio0 8 GPIO_ACTIVE_HIGH>; gpio-fan,speed-map = <0 0 3000 1>; pinctrl-0 = <&fan_pins>; pinctrl-names = "default"; }; gpio_leds { compatible = "gpio-leds"; pinctrl-names = "default"; pinctrl-0 = <&led_pins>; sw_led { label = "370rd:green:sw"; gpios = <&gpio1 0 GPIO_ACTIVE_LOW>; default-state = "keep"; }; }; nand@d0000 { status = "okay"; num-cs = <1>; marvell,nand-keep-config; marvell,nand-enable-arbiter; nand-on-flash-bbt; partition@0 { label = "U-Boot"; reg = <0 0x800000>; }; partition@800000 { label = "Linux"; reg = <0x800000 0x800000>; }; partition@1000000 { label = "Filesystem"; reg = <0x1000000 0x3f000000>; }; }; }; }; dsa { status = "disabled"; compatible = "marvell,dsa"; #address-cells = <2>; #size-cells = <0>; dsa,ethernet = <ð1>; dsa,mii-bus = <&mdio>; switch@0 { #address-cells = <1>; #size-cells = <0>; reg = <0x10 0>; /* MDIO address 16, switch 0 in tree */ port@0 { reg = <0>; label = "lan0"; }; port@1 { reg = <1>; label = "lan1"; }; port@2 { reg = <2>; label = "lan2"; }; port@3 { reg = <3>; label = "lan3"; }; port@5 { reg = <5>; label = "cpu"; }; }; }; }; &pciec { status = "okay"; /* Internal mini-PCIe connector */ pcie@1,0 { /* Port 0, Lane 0 */ status = "okay"; }; /* Internal mini-PCIe connector */ pcie@2,0 { /* Port 1, Lane 0 */ status = "okay"; }; }; &mdio { pinctrl-0 = <&mdio_pins>; pinctrl-names = "default"; phy0: ethernet-phy@0 { reg = <0>; }; switch: switch@10 { compatible = "marvell,mv88e6085"; #address-cells = <1>; #size-cells = <0>; reg = <0x10>; ports { #address-cells = <1>; #size-cells = <0>; port@0 { reg = <0>; label = "lan0"; }; port@1 { reg = <1>; label = "lan1"; }; port@2 { reg = <2>; label = "lan2"; }; port@3 { reg = <3>; label = "lan3"; }; port@5 { reg = <5>; label = "cpu"; ethernet = <ð1>; fixed-link { speed = <1000>; full-duplex; }; }; }; }; }; &pinctrl { fan_pins: fan-pins { marvell,pins = "mpp8"; marvell,function = "gpio"; }; led_pins: led-pins { marvell,pins = "mpp32"; marvell,function = "gpio"; }; };
