From 68081fc1c8c7814b1c064431eb2e364f9226801a Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Sat, 9 Nov 2013 19:29:46 +0000 Subject: [PATCH] brcm47xx: register ADM6996L switch This patch makes it possible to use adm6996.c on first generation BCM47XX devices with ADM switches. This was tested on a WRT54GS version 1.0, thank you Dirk Neukirchen for the device.
