[LEDE-DEV] [PATCH] brcm63xx: Add Observa VH4032N support

Wed Nov 30 11:51:43 PST 2016


Add support for the Observa Telecom VH4032N router.

This is another BCM6368 router, 128 MB RAM, 32MB flash and 3 USB
host ports. It has an onboard USB hub that needs to be pulled out of
reset via GPIO27. 

The 4 LAN switch LEDs should be controlled via hardware but they don't 
work as with all BCM6368 based boards (known bug, GPIO LAN-LED mux 
is lost at boot time).

The wifi chip is an onboard Broadcom BCM43222.
