This board has been supported in the ar71xx. Links: * https://mikrotik.com/product/RB912UAG-2HPnD * https://mikrotik.com/product/RB912UAG-5HPnD * https://openwrt.org/toh/hwdata/mikrotik/mikrotik_rb912uag-2hpnd * https://openwrt.org/toh/hwdata/mikrotik/mikrotik_rb912uag-5hpnd
Hardware: * SoC: Atheros AR9342, * RAM: DDR 64MB, * SPI NOR: 64KB, * NAND: 128MB, * Ethernet: x1 10/100/1000 port with passive POE in, * Wi-Fi: 802.11bgn, * PCIe, * USB: 2.0 EHCI controller, connected to mPCIe slot and a Type-A port -- both can be used for LTE modem. But only one can be used. * LEDs: 5 general purpose LEDs (led1..led5), power LED, user LED, Ethernet phy LED, * Button, * Beeper. Not working: * Button: it shares gpio line 15 with NAND ALE and NAND IO7, and current drivers doesn't easily support this configuration, * Beeper: it is connected to bit 5 of a serial shift register (tested with sysfs led trigger timer). But kmod-gpio-beeper doesn't work -- we left this as is for now. You can flash image by sysupgrade utility or load it by net (by DHCP/TFTP, hold the button while booting). Co-Developed-by: Koen Vandeputte <[email protected]> Signed-off-by: Denis Kalashnikov <[email protected]> --- Changelog: v1->v2: - Delete uneeded comments from DTS, - Delete ascii-art of board scheme near NAND latch from DTS, - Rewrite gpio_latch and nand_gpio nodes to be consistent with the new versions of drivers, - Fix SPI NOR flash and SPI serial shift register maximum speeds (thanks to Koen Vandeputte), - Add UART, PCIe, USB support and gpio exports (thanks to Koen Vandeputte), - Fix Ethernet node (thanks to Koen Vandeputte), - Add key and beeper nodes in disabled state just to be documented. --- .../dts/ar9342_mikrotik_routerboard-912g.dts | 233 ++++++++++++++++++ target/linux/ath79/image/mikrotik.mk | 9 + .../base-files/etc/board.d/02_network | 2 + .../etc/hotplug.d/firmware/10-ath9k-eeprom | 1 + .../base-files/lib/upgrade/platform.sh | 1 + 5 files changed, 246 insertions(+) create mode 100644 target/linux/ath79/dts/ar9342_mikrotik_routerboard-912g.dts diff --git a/target/linux/ath79/dts/ar9342_mikrotik_routerboard-912g.dts b/target/linux/ath79/dts/ar9342_mikrotik_routerboard-912g.dts new file mode 100644 index 0000000000..a23fc04a99 --- /dev/null +++ b/target/linux/ath79/dts/ar9342_mikrotik_routerboard-912g.dts @@ -0,0 +1,233 @@ +// SPDX-License-Identifier: GPL-2.0-or-later + +#include "ar9344.dtsi" + +#include <dt-bindings/gpio/gpio.h> +#include <dt-bindings/input/input.h> + +/ { + compatible = "mikrotik,routerboard-912g", "qca,ar9342";
