From afe0320ffc212b405e068281d636626df754261e Mon Sep 17 00:00:00 2001 From: INAGAKI Hiroshi Date: Wed, 16 May 2018 21:42:48 +0900 Subject: ramips: add support for I-O DATA WN-GX300GR I-O DATA WN-GX300GR is a 2.4 GHz band 11n router, based on MediaTek MT7621S. Specification: - MT7621S (1-Core, 2-Threads) - 64 MB of RAM - 8 MB of Flash (SPI) - 2T2R 2.4 GHz - 5x 10/100/1000 Mbps Ethernet - 2x LEDs, 4x keys (2x buttons, 1x slide switch) - UART header on PCB - Vcc, GND, TX, RX from ethernet port side - baudrate: 115200 bps (U-Boot, OpenWrt) Flash instruction using initramfs image: 1. Connect serial cable to UART header 2. Rename OpenWrt initramfs image for WN-GX300GR to "uImageWN-GX300GR" and place it in the TFTP directory 3. Set the IP address of the computer to 192.168.99.8, connect to the LAN port of WN-GX300GR, and start the TFTP server on the computer 4. Connect power cable to WN-GX300GR and turn on the router 5. Press "1" key on the serial console to interrupt boot process on U-Boot, press Enter key 3 times and start firmware download via TFTP 6. WN-GX300GR downloads initramfs image and boot with it 7. On the initramfs image, execute "mtd erase firmware" to erase stock firmware and execute sysupgrade with sysupgrade image for WN-GX300GR 8. Wait ~150 seconds to complete flasing Signed-off-by: INAGAKI Hiroshi --- target/linux/ramips/dts/WN-GX300GR.dts | 156 +++++++++++++++++++++++++++++++++ 1 file changed, 156 insertions(+) create mode 100644 target/linux/ramips/dts/WN-GX300GR.dts (limited to 'target/linux/ramips/dts') diff --git a/target/linux/ramips/dts/WN-GX300GR.dts b/target/linux/ramips/dts/WN-GX300GR.dts new file mode 100644 index 0000000000..aa89f05555 --- /dev/null +++ b/target/linux/ramips/dts/WN-GX300GR.dts @@ -0,0 +1,156 @@ +/dts-v1/; + +#include "mt7621.dtsi" + +#include +#include + +/ { + compatible = "iodata,wn-gx300gr", "mediatek,mt7621-soc"; + model = "I-O DATA WN-GX300GR"; + + memory@0 { + device_type = "memory"; + reg = <0x0 0x4000000>; + }; + + chosen { + bootargs = "console=ttyS0,115200"; + }; + + gpio-leds { + compatible = "gpio-leds"; + + power { + label = "wn-gx300gr:green:power"; + gpios = <&gpio0 7 GPIO_ACTIVE_LOW>; + }; + + wps { + label = "wn-gx300gr:green:wps"; + gpios = <&gpio0 17 GPIO_ACTIVE_LOW>; + }; + }; + + gpio-keys-polled { + compatible = "gpio-keys-polled"; + #address-cells = <1>; + #size-cells = <0>; + poll-interval = <20>; + + reset { + label = "reset"; + gpios = <&gpio0 10 GPIO_ACTIVE_LOW>; + linux,code = ; + }; + + wps { + label = "wps"; + gpios = <&gpio0 14 GPIO_ACTIVE_LOW>; + linux,code = ; + }; + + auto { + label = "auto"; + gpios = <&gpio0 15 GPIO_ACTIVE_LOW>; + linux,code = ; + linux,input-type = ; + }; + + custom { + label = "custom"; + gpios = <&gpio0 16 GPIO_ACTIVE_LOW>; + linux,code = ; + linux,input-type = ; + }; + }; +}; + +&spi0 { + status = "okay"; + + m25p80@0 { + #address-cells = <1>; + #size-cells = <1>; + compatible = "jedec,spi-nor"; + reg = <0>; + spi-max-frequency = <10000000>; + m25p,chunked-io = <32>; + + partition@0 { + label = "Bootloader"; + reg = <0x0 0x30000>; + read-only; + }; + + partition@30000 { + label = "Config"; + reg = <0x30000 0x10000>; + read-only; + }; + + Factory: partition@40000 { + label = "Factory"; + reg = <0x40000 0x10000>; + read-only; + }; + + partition@50000 { + label = "iNIC_rf"; + reg = <0x50000 0x10000>; + read-only; + }; + + partition@60000 { + label = "firmware"; + reg = <0x60000 0x770000>; + }; + + partition@7d0000 { + label = "Key"; + reg = <0x7d0000 0x10000>; + read-only; + }; + + partition@7e0000 { + label = "backup"; + reg = <0x7e0000 0x10000>; + read-only; + }; + + partition@7f0000 { + label = "storage"; + reg = <0x7f0000 0x10000>; + read-only; + }; + }; +}; + +ðernet { + mtd-mac-address = <&Factory 0x4>; +}; + +&pinctrl { + state_default: pinctrl0 { + gpio { + ralink,group = "uart2", "uart3", "jtag"; + ralink,function = "gpio"; + }; + }; +}; + +&pcie { + status = "okay"; + + pcie0 { + mt76@0,0 { + reg = <0x0000 0 0 0 0>; + device_type = "pci"; + mediatek,mtd-eeprom = <&Factory 0x0>; + }; + }; +}; + +&xhci { + status = "disabled"; +}; -- cgit v1.2.3
