From: Denis Kalashnikov <denis281089 at gmail.com>
This board has been supported in the ar71xx.
Links:
* https://mikrotik.com/product/RB912UAG-2HPnD
* https://openwrt.org/toh/hwdata/mikrotik/mikrotik_rb912uag-2hpnd
Hardware:
* SoC: Atheros AR9342,
* RAM: DDR 64MB,
* SPI NOR: 64KB,
* NAND: 128MB,
* Ethernet: x1 10/100/1000 port with passive POE in,
* Wi-Fi: 802.11 b/g/n,
* 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.
Flashing:
* Use the RouterBOARD Reset button to enable TFTP netboot,
boot kernel and initramfs and then perform sysupgrade.
* From ar71xx OpenWrt firmware run:
$ sysupgrade -F /tmp/<sysupgrade.bin>

Changelog:
RFC v1 --> RFC 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.
RFC v2 --> v1
- Add led aliases -- now OpenWrt controls power led,
- Remove disabled nodes (reset key and gpio-beeper),
- Fix gpio-export node,
- Fix model name,
- Move gpio_nand and gpio_latch nodes from ahb node to the root node.
