From 20fe2176e5edbeb5957f113df1282a917ef87b5d Mon Sep 17 00:00:00 2001 From: Daniel Drake Date: Sat, 12 Aug 2006 17:59:42 +0100 Subject: [PATCH] [PATCH] zd1211rw: AL2230 ZD1211B vendor sync This patch synchronizes our code to some recent vendor driver modifications. A new PHY layout is supported, some values are tweaked, and the AL2230 is now programmed over a new interface which is many times faster. Signed-off-by: Daniel Drake Signed-off-by: John W.
