It is used in recent versions of * DSM software provided by Synology. Nonetheless, some earlier boards * were delivered with an older version of u-boot that left internal * registers mapped at 0xd0000000. If you have such a device you will * not be able to directly boot a kernel based on this Device Tree. In * that case, the preferred solution is to update your bootloader (e.g. * by upgrading to latest version of DSM, or building a new one and * installing it from u-boot prompt) or adjust the Devive Tree * (s/0xf1000000/0xd0000000/ in 'ranges' below). */ /dts-v1/; #include #include #include "armada-370.dtsi" / { model = "Synology DS213j"; compatible = "synology,ds213j", "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 { /* RTC provided by Seiko S-35390A I2C RTC chip below */ rtc@10300 { status = "disabled"; }; i2c@11000 { compatible = "marvell,mv64xxx-i2c"; pinctrl-0 = <&i2c0_pins>; pinctrl-names = "default"; clock-frequency = <400000>; status = "okay"; /* Main device RTC chip */ s35390a: s35390a@30 { compatible = "sii,s35390a"; reg = <0x30>; }; }; /* Connected to a header on device's PCB */ serial@12000 { status = "okay"; }; /* Connected to a TI MSP430F2111 for power control */ serial@12100 { status = "okay"; }; poweroff@12100 { compatible = "synology,power-off"; reg = <0x12100 0x100>; clocks = <&coreclk 0>; }; /* rear USB port, near reset button */ usb@50000 { status = "okay"; }; /* rear USB port, near RJ45 port */ usb@51000 { status = "okay"; }; ethernet@70000 { status = "okay"; phy = <&phy1>; phy-mode = "sgmii"; }; sata@a0000 { nr-ports = <2>; status = "okay"; }; }; }; gpio-fan-32-38 { status = "okay"; compatible = "gpio-fan"; pinctrl-0 = <&fan_ctrl_low_pin &fan_ctrl_mid_pin &fan_ctrl_high_pin &fan_alarm_pin>; pinctrl-names = "default"; gpios = <&gpio1 31 GPIO_ACTIVE_HIGH &gpio2 0 GPIO_ACTIVE_HIGH &gpio2 1 GPIO_ACTIVE_HIGH>; alarm-gpios = <&gpio1 6 GPIO_ACTIVE_HIGH>; gpio-fan,speed-map = < 0 0 1000 1 1150 2 1350 4 1500 3 1650 5 1750 6 1900 7 >; }; gpio-leds { compatible = "gpio-leds"; pinctrl-0 = <&disk1_led_pin &disk2_led_pin>; pinctrl-names = "default"; disk1-led-amber { label = "synology:amber:disk1"; gpios = <&gpio0 31 GPIO_ACTIVE_LOW>; default-state = "keep"; }; disk2-led-amber { label = "synology:amber:disk2"; gpios = <&gpio1 0 GPIO_ACTIVE_LOW>; default-state = "keep"; }; }; regulators { compatible = "simple-bus"; #address-cells = <1>; #size-cells = <0>; pinctrl-0 = <&sata1_pwr_pin &sata2_pwr_pin>; pinctrl-names = "default"; sata1_regulator: sata1-regulator { compatible = "regulator-fixed"; reg = <1>; regulator-name = "SATA1 Power"; regulator-min-microvolt = <5000000>; regulator-max-microvolt = <5000000>; startup-delay-us = <2000000>; enable-active-high; regulator-always-on; regulator-boot-on; gpio = <&gpio1 5 GPIO_ACTIVE_HIGH>; }; sata2_regulator: sata2-regulator { compatible = "regulator-fixed"; reg = <2>; regulator-name = "SATA2 Power"; regulator-min-microvolt = <5000000>; regulator-max-microvolt = <5000000>; startup-delay-us = <4000000>; enable-active-high; regulator-always-on; regulator-boot-on; gpio = <&gpio1 30 GPIO_ACTIVE_HIGH>; }; }; }; &mdio { phy1: ethernet-phy@1 { /* Marvell 88E1512 */ reg = <1>; }; }; &pinctrl { disk1_led_pin: disk1-led-pin { marvell,pins = "mpp31"; marvell,function = "gpio"; }; disk2_led_pin: disk2-led-pin { marvell,pins = "mpp32"; marvell,function = "gpio"; }; sata1_pwr_pin: sata1-pwr-pin { marvell,pins = "mpp37"; marvell,function = "gpio"; }; sata2_pwr_pin: sata2-pwr-pin { marvell,pins = "mpp62"; marvell,function = "gpio"; }; sata1_pres_pin: sata1-pres-pin { marvell,pins = "mpp60"; marvell,function = "gpio"; }; sata2_pres_pin: sata2-pres-pin { marvell,pins = "mpp48"; marvell,function = "gpio"; }; syno_id_bit0_pin: syno-id-bit0-pin { marvell,pins = "mpp55"; marvell,function = "gpio"; }; syno_id_bit1_pin: syno-id-bit1-pin { marvell,pins = "mpp56"; marvell,function = "gpio"; }; syno_id_bit2_pin: syno-id-bit2-pin { marvell,pins = "mpp57"; marvell,function = "gpio"; }; syno_id_bit3_pin: syno-id-bit3-pin { marvell,pins = "mpp58"; marvell,function = "gpio"; }; fan_ctrl_low_pin: fan-ctrl-low-pin { marvell,pins = "mpp65"; marvell,function = "gpio"; }; fan_ctrl_mid_pin: fan-ctrl-mid-pin { marvell,pins = "mpp64"; marvell,function = "gpio"; }; fan_ctrl_high_pin: fan-ctrl-high-pin { marvell,pins = "mpp63"; marvell,function = "gpio"; }; fan_alarm_pin: fan-alarm-pin { marvell,pins = "mpp38"; marvell,function = "gpio"; }; }; &spi0 { status = "okay"; spi-flash@0 { #address-cells = <1>; #size-cells = <1>; compatible = "micron,n25q064", "jedec,spi-nor"; reg = <0>; /* Chip select 0 */ spi-max-frequency = <20000000>; /* * Warning! * * Synology u-boot uses its compiled-in environment * and it seems Synology did not care to change u-boot * default configuration in order to allow saving a * modified environment at a sensible location.
