From d342b95dd735014a590f9051b1ba227eb54ca8f6 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Rafa=C5=82=20Mi=C5=82ecki?= Date: Thu, 31 Jul 2014 21:59:43 +0200 Subject: [PATCH] b43: don't duplicate common PHY read/write ops MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Most of the PHYs use the same way of accessing registers, so move that code to the shared place. An exception is G-PHY which sometimes access A-PHY regs and requires special handling. Signed-off-by: Rafał Miłecki Signed-off-by: John W.
