From 47583154767886a97a82452c8aca63bf0336337a Mon Sep 17 00:00:00 2001 From: =?utf8?q?G=C3=A1bor=20Stefanik?= Date: Tue, 11 Aug 2009 22:24:22 +0200 Subject: [PATCH] b43: LP-PHY: Refactor TX gain table I/O MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Make it possible to write individual gain table entries. Allow gain table entries to be written outside gain table init. Add version-agnostic helpers for writing gain tables. Use the new TX gain table helpers during table init.
