ramips: add support for Qding QC202
This is a smart door lock device equipped with OpenWrt 14.07 OEM modified version Qdwrt The OEM has closed down, This commit is intended to maximize the remaining value of these devices. It can flash OpenWrt to become an AP WARNING: The original firmware does not use the device tree. This device tree is written based on the content of /sys/devices/platform and has been tested WARNING: If flash device with breed-mt7688-reset38.bin, please reflash original bootloader after flash ROM. Breed will cause RTC 2082-year problem, and wrong GPIOs. Specification: - SoC: MediaTek MT7628NN - Flash: 8 MB - RAM: 64 MB - Power: DC 5V - 25V - Ethernet: 1 x RJ45 (10/100 Mbps) - Wireless radio: 802.11n 2.4g-only - On-Board LED: Ethernet: GPIO 43/555 active-low Wifi: GPIO 44/556 active-low Power: AlwaysOn - Button: WPS / RESET: GPIO 14/526 active-low - Bluetooth: CC2541 - RFID: MF RC522 on I2C@28 - RTC: DS1339 on I2C@68 - Matrix keypad LED: Green GPIO 3/515 active-high, Red GPIO 11/523 active-high, Yellow = Green + Red - UART: 1 x UART on PCB - 57600 8N1 - GPIO Relay: GPIO 42/554 active-high - GPIO Buzzer: GPIO 15/527 active-high Issue: - No drivers in mainline kernel for RFID. - Bluetooth not working. The bus is not known yet, and no driver in mainline kernel. - Matrix keypad not working. Flash with Breed (Verified): 1. Connect the board to the computer via RJ45 Ethernet 2. Login 10.10.10.1 with root password "szqdingnet123" (SSH Port 22, Telnet Port 9900) Backup bootloader (mtdblock1) and download to computer. It is best to backup the full original firmware. 3. Download breed-mt7688-reset38.bin and BreedEnter.zip from https://breed.hackpascal.net/ 4. Setup a http server on computer. And use wget download breed from computer 5. Use command "mtd write breed-mt7688-reset38.bin Bootloader" to flash breed 6. Open the Breed Enter and restart board. 7. Flash ROM and original uboot via Breed Web UI. It is best to backup the full flash and eeprom in Breed Web UI.
