From mboxrd@z Thu Jan 1 00:00:00 1970 From: Karsten Keil Subject: [PATCH 10/28] mISDN: Add interface for PCM only access Date: Sat, 17 Mar 2012 15:54:33 +0100 Message-ID: <20120423170550.194D19FB78@pingi6.linux-pingi.de> Cc: netdev@vger.kernel.org, isdn4linux@listserv.isdn4linux.de To: David Miller Return-path: Received: from moutng.kundenserver.de ([212.227.126.171]:59593 "EHLO moutng.kundenserver.de" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1752690Ab2DWRIW (ORCPT ); Mon, 23 Apr 2012 13:08:22 -0400 Sender: netdev-owner@vger.kernel.org List-ID: Sometimes the ISDN chip only control the D-channel and B-channel are only accessed via the PCM interface. Add infrastruckture for this mode.
