From 72ef5945508193228544bcd7fcfe81b32e8dc042 Mon Sep 17 00:00:00 2001 From: Sven Eckelmann Date: Mon, 23 Nov 2020 13:41:34 +0100 Subject: ath79: Add support for OpenMesh OM5P-AN Device specifications: ====================== * Qualcomm/Atheros AR9344 rev 2 * 560/450/225 MHz (CPU/DDR/AHB) * 64 MB of RAM * 16 MB of SPI NOR flash - 2x 7 MB available; but one of the 7 MB regions is the recovery image * 1T1R 2.4 GHz Wi-Fi * 2T2R 5 GHz Wi-Fi * 6x GPIO-LEDs (3x wifi, 2x ethernet, 1x power) * 1x GPIO-button (reset) * external h/w watchdog (enabled by default) * TTL pins are on board (arrow points to VCC, then follows: GND, TX, RX) * TI tmp423 (package kmod-hwmon-tmp421) for temperature monitoring * 2x ethernet - eth0 + AR8035 ethernet PHY + 10/100/1000 Mbps Ethernet + 802.3af POE + used as LAN interface - eth1 + 10/100 Mbps Ethernet + builtin switch port 1 + 18-24V passive POE (mode B) + used as WAN interface * 12-24V 1A DC * internal antennas Flashing instructions: ====================== Various methods can be used to install the actual image on the flash. Two easy ones are: ap51-flash ---------- The tool ap51-flash (https://github.com/ap51-flash/ap51-flash) should be used to transfer the image to the u-boot when the device boots up. initramfs from TFTP ------------------- The serial console must be used to access the u-boot shell during bootup. It can then be used to first boot up the initramfs image from a TFTP server (here with the IP 192.168.1.21): setenv serverip 192.168.1.21 setenv ipaddr 192.168.1.1 tftpboot 0c00000 .bin && bootm $fileaddr The actual sysupgrade image can then be transferred (on the LAN port) to the device via scp .bin root@192.168.1.1:/tmp/ On the device, the sysupgrade must then be started using sysupgrade -n /tmp/.bin Signed-off-by: Sven Eckelmann --- target/linux/ath79/dts/ar9344_openmesh_om5p-an.dts | 230 +++++++++++++++++++++ 1 file changed, 230 insertions(+) create mode 100644 target/linux/ath79/dts/ar9344_openmesh_om5p-an.dts (limited to 'target/linux/ath79/dts') diff --git a/target/linux/ath79/dts/ar9344_openmesh_om5p-an.dts b/target/linux/ath79/dts/ar9344_openmesh_om5p-an.dts new file mode 100644 index 0000000000..e15e296f82 --- /dev/null +++ b/target/linux/ath79/dts/ar9344_openmesh_om5p-an.dts @@ -0,0 +1,230 @@ +// SPDX-License-Identifier: GPL-2.0-or-later OR MIT + +#include "ar9344.dtsi" + +#include +#include + +/ { + compatible = "openmesh,om5p-an", "qca,ar9344"; + model = "OpenMesh OM5P-AN"; + + chosen { + /delete-property/ bootargs; + }; + + aliases { + led-boot = &led_power_blue; + led-failsafe = &led_power_blue; + led-running = &led_power_blue; + led-upgrade = &led_power_blue; + label-mac-device = ð0; + }; + + keys { + compatible = "gpio-keys"; + + reset { + label = "reset"; + linux,code = ; + gpios = <&gpio 4 GPIO_ACTIVE_LOW>; + }; + }; + + leds { + compatible = "gpio-leds"; + + pinctrl-names = "default"; + pinctrl-0 = <&led_lan_wan_blue_pin>; + + led_power_blue: power_blue { + label = "blue:power"; + gpios = <&gpio 13 GPIO_ACTIVE_LOW>; + default-state = "on"; + }; + + wan_blue { + label = "blue:wan"; + gpios = <&gpio 14 GPIO_ACTIVE_LOW>; + }; + + lan_blue { + label = "blue:lan"; + gpios = <&gpio 15 GPIO_ACTIVE_LOW>; + }; + + wifi_green { + label = "green:wifi"; + gpios = <&gpio 16 GPIO_ACTIVE_LOW>; + linux,default-trigger = "phy0tpt"; + }; + + wifi_yellow { + label = "yellow:wifi"; + gpios = <&gpio 17 GPIO_ACTIVE_LOW>; + }; + + wifi_red { + label = "red:wifi"; + gpios = <&gpio 19 GPIO_ACTIVE_LOW>; + }; + }; + + i2c { + compatible = "i2c-gpio"; + gpios = <&gpio 21 GPIO_ACTIVE_HIGH /* sda */ + &gpio 20 GPIO_ACTIVE_HIGH /* scl */ + >; + #address-cells = <1>; + #size-cells = <0>; + + i2c-gpio,scl-open-drain; + i2c-gpio,sda-open-drain; + + tmp423a@4c { + compatible = "ti,tmp423"; + reg = <0x4c>; + }; + }; + + watchdog { + compatible = "linux,wdt-gpio"; + gpios = <&gpio 11 GPIO_ACTIVE_LOW>; + hw_algo = "toggle"; + /* hw_margin_ms is actually 300s but driver limits it to 60s */ + hw_margin_ms = <60000>; + always-running; + }; +}; + +&ref { + clock-frequency = <40000000>; +}; + +&pinmux { + led_lan_wan_blue_pin: pinmux_lan_wan_blue_pin { + pinctrl-single,bits = <0xc 0x0 0xffff0000>; + }; +}; + +&spi { + status = "okay"; + + flash@0 { + compatible = "jedec,spi-nor"; + reg = <0>; + spi-max-frequency = <40000000>; + + /* partitions are passed via bootloader */ + partitions { + compatible = "fixed-partitions"; + #address-cells = <1>; + #size-cells = <1>; + + partition@0 { + label = "u-boot"; + reg = <0x000000 0x040000>; + read-only; + }; + + partition@40000 { + label = "u-boot-env"; + reg = <0x040000 0x010000>; + }; + + partition@50000 { + label = "custom"; + reg = <0x050000 0x060000>; + read-only; + }; + + partition@b0000 { + label = "inactive"; + reg = <0x0b0000 0x7a0000>; + }; + + partition@850000 { + label = "inactive2"; + reg = <0x850000 0x7a0000>; + }; + + art: partition@ff0000 { + label = "ART"; + reg = <0xff0000 0x010000>; + read-only; + }; + }; + }; +}; + +&mdio0 { + status = "okay"; + + phy-mask = <0x80>; + + phy7: ethernet-phy@7 { + reg = <7>; + eee-broken-100tx; + eee-broken-1000t; + }; +}; + +ð0 { + status = "okay"; + + pll-data = <0x02000000 0x00000101 0x00001313>; + + nvmem-cells = <&macaddr_art_0>; + nvmem-cell-names = "mac-address"; + + phy-mode = "rgmii-id"; + phy-handle = <&phy7>; + + gmac-config { + device = <&gmac>; + rgmii-gmac0 = <1>; + rxd-delay = <2>; + rxdv-delay = <2>; + switch-phy-swap = <1>; + }; +}; + +ð1 { + status = "okay"; + + nvmem-cells = <&macaddr_art_0>; + nvmem-cell-names = "mac-address"; + mac-address-increment = <1>; +}; + +&wmac { + status = "okay"; + + mtd-cal-data = <&art 0x1000>; + nvmem-cells = <&macaddr_art_0>; + nvmem-cell-names = "mac-address"; + mac-address-increment = <2>; +}; + +&pcie { + status = "okay"; + + wifi@0,0 { + compatible = "pci168c,0030"; + reg = <0x0000 0 0 0 0>; + qca,no-eeprom; + nvmem-cells = <&macaddr_art_0>; + nvmem-cell-names = "mac-address"; + mac-address-increment = <16>; + }; +}; + +&art { + compatible = "nvmem-cells"; + #address-cells = <1>; + #size-cells = <1>; + + macaddr_art_0: macaddr@0 { + reg = <0x0 0x6>; + }; +}; -- cgit v1.2.3
