[alsa-devel] [PATCH 0/5] ALSA: oxfw: code refactoring for model-dependent quirks
Hi,
ALSA oxfw driver has got some patches to expand its functionalities. As a result, current code includes some inefficiencies and confusions.
This patchset is a code refactoring about model-dependent quirks. This patchset is a part of my previous RFCv2 (patch 01-05) and a preparation for the rest of patches:
[alsa-devel] [RFC][PATCH 00/17 v2] ALSA: oxfw: refactoring and merging scs1x module http://mailman.alsa-project.org/pipermail/alsa-devel/2015-December/101558.ht...
Takashi Sakamoto (5): ALSA: oxfw: rename a file for control elements so that it's for model-specific ALSA: oxfw: rename local functions for control elements so that they represent as local ALSA: oxfw: change function prototype for AV/C Audio Subunit command ALSA: oxfw: reuse driver entry to detect quirk ALSA: oxfw: gather model-dependent conditions to a function
sound/firewire/oxfw/Makefile | 4 +- .../firewire/oxfw/{oxfw-control.c => oxfw-spkr.c} | 80 ++++++++++++---------- sound/firewire/oxfw/oxfw.c | 59 +++++++++------- sound/firewire/oxfw/oxfw.h | 6 +- 4 files changed, 86 insertions(+), 63 deletions(-) rename sound/firewire/oxfw/{oxfw-control.c => oxfw-spkr.c} (71%)
In ALSA firewire stack, drivers basically has no control elements. This is due to the fact that each model has own functionality even if they use the same communication chipset. Implementing all of the functionalities in kernel space unreasonably increases our efforts to maintain the stack. In most case, these functionalities can be implemented in userspace via Linux fw character devices.
However, ALSA OXFW driver has control elements comes from old firewire-speakers driver. Adding the elements is in a file names as 'oxfw-control.c', while the elements are really model-specific. The name is confusing because it gives an idea to handle control elements for all of OXFW-based models.
This commit renames the file so that it's just for models supported by old firewire-speakers driver.

ALSA OXFW driver uses AV/C Audio Subunit commands to control some models. The commands get/set the state of Feature function block of the subunit. The commands are not specific to OXFW, thus there's a possibility to use them in the other drivers.
Currently, helper functions for the commands require 'struct snd_oxfw', although, it's not necessarily required. It's better to change prototype of the functions without the structure for future use.
This commit changes the prototype.

Currently, assignment to model-dependent quirk is corresponding to asynchronous transactions on IEEE 1394 bus. This is also achieved with device entry.
This commit changes the processing of model-dependent quirk with the entry. As a result, the transactions are sent only for Loud models.

Hi,
ALSA oxfw driver has got some patches to expand its functionalities. As a result, current code includes some inefficiencies and confusions.
This patchset is a code refactoring about model-dependent quirks. This patchset is a part of my previous RFCv2 (patch 01-05) and a preparation for the rest of patches:
[alsa-devel] [RFC][PATCH 00/17 v2] ALSA: oxfw: refactoring and merging scs1x module http://mailman.alsa-project.org/pipermail/alsa-devel/2015-December/101558.ht...
Takashi Sakamoto (5): ALSA: oxfw: rename a file for control elements so that it's for model-specific ALSA: oxfw: rename local functions for control elements so that they represent as local ALSA: oxfw: change function prototype for AV/C Audio Subunit command ALSA: oxfw: reuse driver entry to detect quirk ALSA: oxfw: gather model-dependent conditions to a function
Applied all five patches. Thanks.

If possible, would you please apply fireworks patches on 'topic/firewire-update' to 'for-next' branch, too?
