Zyxel EX3510-B is a WiFi 6 capable home gateway (family) based on the
BCM4906 SoC, with 512MiB of RAM and 512MiB of NAND flash. WiFi support
consists of a BCM6710 and a BCM6715 attached to separate PCIe buses.
Add an initial devicetree for this system, with support for:
- Onboard UART (per base dtsi)
- USB (2.0 only; superspeed devices are treated as high-speed due to an
unknown cause)
- Both buttons (rear reset, front WPS)
- Almost all LEDs:
- Power (red/green)
- Internet (red/green)
- WAN (green)
- LAN (green; anode is connected to GPIO 13 so currently
nonfunctioning)
- USB (green)
- WPS button (red/green)
- Absent in DT: There are 2.4GHz/5.0GHz WiFi status LEDs connected to
the WiFi chips instead of the SoC.
- NAND flash
- Embedded Ethernet switch
- Factory-programmed Ethernet MAC address
WiFi cannot be enabled at this time due to Linux lacking drivers for
both the PCIe controllers and the PCIe WiFi peripherals.
