From mboxrd@z Thu Jan 1 00:00:00 1970 From: Takashi Sakamoto Subject: [PATCH 41/44] bebob: Add support for M-Audio special Firewire series Date: Fri, 21 Mar 2014 20:10:26 +0900 Message-ID: <1395400229-22957-42-git-send-email-o-takashi@sakamocchi.jp> References: <1395400229-22957-1-git-send-email-o-takashi@sakamocchi.jp> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Return-path: In-Reply-To: <1395400229-22957-1-git-send-email-o-takashi@sakamocchi.jp> List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: linux1394-devel-bounces@lists.sourceforge.net To: clemens@ladisch.de, tiwai@suse.de, perex@perex.cz Cc: alsa-devel@alsa-project.org, linux1394-devel@lists.sourceforge.net, ffado-devel@lists.sf.net List-Id: alsa-devel@alsa-project.org This commit allows this driver to support some models which M-Audio produces with DM1000 but its firmware is special. They are: - Firewire 1814 - ProjectMix I/O They have heavily customized firmware. The usual operations can't be applied to them. For this reason, this commit adds a model specific member in 'struct snd_bebob' and some model specific functions. Some parameters are write-only so this commit also adds control interface for applications to set them. M-Audio special firmware quirks: - Just after powering on, they wait to download firmware. This state is changed when receiving cue. Then bus reset is generated and the device is recognized as a different model with the uploaded firmware. - They don't respond against BridgeCo AV/C extension commands. So drivers can't get their stream formations and so on. - They do not start to transmit packets only by establishing connection but also by receiving SIGNAL FORMAT command. - After booting up, they often fail to send response against driver's request due to mismatch of gap_count. This module don't support to upload firmware.
