[PATCH v3 3/4] ARM: dts: NSP: Add DT files for Meraki MX65 series

From: Matthew Hagan
Date: Sun Jun 13 2021 - 06:19:24 EST


MX65 & MX65W Hardware info:
- CPU: Broadcom BCM58625 Cortex A9 @ 1200Mhz
- RAM: 2 GB (4 x 4Gb SK Hynix H5TC4G83CFR)
- Storage: 1 GB (Micron MT29F8G08ABACA)
- Networking: BCM58625 switch (2x 1GbE ports)
2x Qualcomm QCA8337 switches (10x 1GbE ports total)
- PSE: Broadcom BCM59111KMLG connected to LAN ports 11 & 12
- USB: 1x USB2.0
- Serial: Internal header
- WLAN(MX65W Only): 2x Broadcom BCM43520KMLG on the PCI bus.

Note that a driver and firmware image for the BCM59111 PSE has been
released under GPL, but this is not present in the kernel.
