Cudy WR1300 v4 is a MT7621 based dual-band router.
Hardware:
- SoC: MediaTek MT7621
- RAM: 128 MiB
- Flash: 16 MiB SPI NOR
- WiFi 2.4 GHz: MediaTek MT7603E
- WiFi 5 GHz: MediaTek MT7663E
- Ethernet: 5x 10/100/1000 Mbps
- Buttons: Reset, WPS
- LEDs: System, Internet, WAN, LAN1-4, WiFi 2.4 GHz, WiFi 5 GHz
The v4 hardware differs from v3 in GPIO assignments for LEDs and
buttons. WiFi LEDs are connected to MT7621 GPIO5/GPIO6 and require
the uart3 pin group to be muxed as GPIO.
All HW versions are quite similar. Wouldn't it make sense to write a
single .dtsi file with all variations in #ifdef ... #endif?
Then you simply write:
wr1300_v1.dts:
#define WR1300_V1
#include "wr1300.dtsi"
(and so on).
Tested on retail Cudy WR1300 v4:
- sysupgrade image boots
- WAN and LAN1-4
- 2.4 GHz and 5 GHz WiFi
- Reset and WPS button events
- System, Internet, WAN, LAN1-4 and WiFi LEDs

(as alternative) wouldn't it be better to rename this file to
mt7621_cudy_wr1300-v2v3v4.dtsi (or ...v2-v4...) or even better just
mt7621_cudy_wr1300-common.dtsi?
