From 96909e97716de1d86e6e24d6aabce09980372771 Mon Sep 17 00:00:00 2001 From: =?utf8?q?G=C3=A1bor=20Stefanik?= Date: Sun, 16 Aug 2009 01:15:49 +0200 Subject: [PATCH] b43: LP-PHY: Update baseband init for recent spec changes MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The spec had some nasty typos, and a large part of the rev0/1 BB init procedure was also missing. Fix these. Also make the init-time channel switch debuggable. (The change from -EINVAL to -EIO is simply to make it possible to distinguish the PLL charge pump error from a channel-not-found error.)
