From 8a4dc6f48c0a4503b655195846ae1bff9a691a40 Mon Sep 17 00:00:00 2001 From: Christian Mauderer Date: Fri, 15 Mar 2019 21:02:54 +0100 Subject: ath79: add support for Ubiquiti airCube ISP MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The Ubiquiti Network airCube ISP is a cube shaped 2.4 GHz with internal 2x2 MIMO antennas. It can be supplied via a USB connector or via PoE. There are for 10/100 Mbps ports (1 * WAN + 3 * LAN). There is an optional PoE passthrough from the first LAN port to the WAN port. SoC: Qualcomm / Atheros QCA9533-BL3A RAM: 64 MB DDR2 Flash: 16 MB SPI NOR Ethernet: 4x 10/100 Mbps (1 WAN + 3 LAN) LEDS: 1x via a SPI controller (not yet supported) Buttons: 1x Reset Serial: 1x (only RX and TX); 115200 baud, 8N1 Missing points: - LED not yet supported - Factory upgrade via web IF or TFTP recovery not yet supported (Needs RSA signed images, for details see PR#1958) The serial port is on a four pin connextor labeled J1 and located between Ethernet and USB connector. The pinout is: 1. 3V3 (out) 2. Rx (in) 3. Tx (out) 4. GND Upgrading via serial port / U-Boot: - Connect the serial port via a level converter - Power the system and stop U-Boot with pressing any key when `Hit any key to stop autoboot` is displayed. Note: Pressing space multiple times untill U-Boot reaches that location works well. - Connect a PC with the IP 192.168.1.100 (or some other in that net) running a TFTP-Server to one of the LAN ports. Copy the sysupgrade image to the server. - Set the U-Boot server IP with setenv serverip 192.168.1.100 - Load the flash image to RAM with tftpboot 0x81000000 sysupgrade.bin - Erase the flash with erase 0x9f050000 0x9ffaffff - Write the new flash content with cp 0x81000000 0x9f050000 ${filesize} - Reset the device with reset Signed-off-by: Christian Mauderer [removed full stop in subject and added lockdown note to commit message] Signed-off-by: Petr Štetiar --- target/linux/ath79/dts/qca9533_ubnt_acb-isp.dts | 95 +++++++++++++++++++++++++ 1 file changed, 95 insertions(+) create mode 100644 target/linux/ath79/dts/qca9533_ubnt_acb-isp.dts (limited to 'target/linux/ath79/dts/qca9533_ubnt_acb-isp.dts') diff --git a/target/linux/ath79/dts/qca9533_ubnt_acb-isp.dts b/target/linux/ath79/dts/qca9533_ubnt_acb-isp.dts new file mode 100644 index 0000000000..3bdaa8ba9b --- /dev/null +++ b/target/linux/ath79/dts/qca9533_ubnt_acb-isp.dts @@ -0,0 +1,95 @@ +// SPDX-License-Identifier: GPL-2.0-or-later OR MIT +/dts-v1/; + +#include +#include + +#include "qca953x.dtsi" + +/ { + compatible = "ubnt,acb-isp", "qca,qca9533"; + model = "Ubiquiti airCube ISP"; + + keys { + compatible = "gpio-keys"; + + reset { + label = "reset"; + linux,code = ; + gpios = <&gpio 17 GPIO_ACTIVE_LOW>; + debounce-interval = <60>; + }; + }; +}; + +&spi { + status = "okay"; + num-cs = <1>; + + flash@0 { + compatible = "jedec,spi-nor"; + reg = <0>; + spi-max-frequency = <25000000>; + + 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>; + read-only; + }; + + partition@50000 { + compatible = "denx,uimage"; + label = "firmware"; + reg = <0x050000 0xf60000>; + }; + + partition@fb0000 { + label = "cfg"; + reg = <0xfb0000 0x040000>; + read-only; + }; + + eeprom: partition@ff0000 { + label = "EEPROM"; + reg = <0xff0000 0x010000>; + read-only; + }; + }; + }; +}; + +&uart { + status = "okay"; +}; + +ð0 { + status = "okay"; + mtd-mac-address = <&eeprom 0x0>; + phy-handle = <&swphy4>; +}; + +ð1 { + status = "okay"; + mtd-mac-address = <&eeprom 0x6>; + + gmac-config { + device = <&gmac>; + }; +}; + +&wmac { + status = "okay"; + mtd-cal-data = <&eeprom 0x1000>; + mtd-mac-address = <&eeprom 0x1002>; +}; -- cgit v1.2.3
