This commit renames 'firewire-speakers' to 'oxfw' to enhance support for devices which based on OXFW970/971. A line for MODULE_ALIAS is added. Additionally, to help for works in followed paches, some members in private structure are renamed. Signed-off-by:

This commit adds a new functions and some arrangement for PCM restriction. This arrangement is due to the number of channels which each Dice device has. I note that minimum number for period becomes 2, instead of 1 because its PCM functionality has SNDRV_PCM_INFO_BATCH, this means that the driver uses double (or more) buffering so the minimum number for period should be 2.

This commit adds a file and move some codes related to hwdep functionality. This interface is designed for mixer/control application. By using hwdep interface, the application can get information about firewire node, can lock/unlock kernel streaming and can get notification at starting/stopping kernel streaming. Additionally, this interface give a way to read Dice notification. Signed-off-by:

This commit adds a file with some helper functions for streaming, and move some codes into the file with some arrangements. Well-known CMP is not used to start/stop streams for Dice chipset. It's achieved by writing to specific address. We call this way as 'enable'. When devices are 'enabled', streaming starts in registered isochronous channel. Some helper functions are already implemented in previous commit. Basically, the stream is compliant to IEC 61883-6, so-called as AMDTP. But Dice has a specific quirk, so called-as 'Dual Wire'. This quirk is applied at 176.4/192.0kHz. In this mode, each packet includes double number of events than number in the specification, and stream runs at a half of sampling rate. There is another quirk at bus reset. Dice chipset handles drivers' request but don't re-enable streaming. So stream should be stopped. Signed-off-by:

This commit adds a file with some helper functions for transaction, and move some codes into the file with some arrangements. For Dice chipset, well-known FCP or AV/C commands are not used to control devices. It's achieved by read/write transactions into specific addresses. Dice's address area is split into 5 areas. Each area has its own role. The offset for each area can be got by reading head of the address area. By reading these areas, drivers can get to know device status. By writing these areas, drivers can change device status. Dice has a specific mechanism called as 'notification'. When device status is changed, Dice devices tells the event by sending transaction. This notification is sent to an address which drivers register in advance. But this causes an issue to drivers. To handle the notification, drivers need to allocate its own callback function to the address region in host controller. This region is exclusive. For the other applications, drivers must give a mechanism to read the received notification. For this purpose, Dice driver already implements hwdep interface. Dice chipset doesn't allow drivers to register several addresses. In this reason, when this driver is applied to a device, the other drivers should _not_ try to register its own address to the device. Signed-off-by:

Currently, dice driver supports AMDTP out-stream. In followed commits, AMDTP in-stream will be supported but current name of members in dice structure are not propper. This commit renames these members to proper name. Additionally, for easily distinguishing local symbols from structure tag, rename dice tag into snd_dice. Signed-off-by:

The commit [7a2e9ddc: ALSA: usb-audio: Add native DSD support for Denon/Marantz DACs] requires the new format definition that has landed only in for-next branch.

Jurgen Kramer authored
Denon/Marantz USB DACs need a specific vendor command to switch between PCM and DSD mode. This patch adds a new quirk function to switch between the two modes using the specific USB vendor command. This patch applies to the following devices: - Marantz SA-14S1 - Marantz HD-DAC1 Signed-off-by:

User can pass snoop option to enable/disable the snoop behavior, but currently azx_check_snoop_available() always turns it off for some devices. For better debuggability, change the parameter as bint, and allow user to enable/disable forcibly the snoop when specified via the module option. Signed-off-by: -
Takashi Iwai authored
Add a new driver_caps bit, AZX_DCAPS_SNOOP_OFF, to set the snoop off as default. This new bit is used for the checks in azx_check_snoop_available(). Most of case-switches are replaced with the new dcaps in each entry. While working on it, for avoiding to spend more bits, combine three bits AZX_DCAPS_SNOOP_SCH, AZX_DCAPS_SNOOP_ATI and AZX_DCAPS_SNOOP_NVIDIA bits into a flat type of two bits. This reduces the bits usages, and assign AZX_DCAPS_OFF to this empty bit now. Signed-off-by:

In olden times the snd_hda_param_read() function always set "*start_id" but in 2007 we introduced a new return and it causes uninitialized data bugs in a couple of the callers: print_codec_info() and hdmi_parse_codec().

Some cards have a so-called low-latency mode, in which they present a single multichannel stream with no mixing or samplerate conversion. In this mode the card can generate an interrupt per internal processing block (typically 32 or 64 frames) Signed-off-by:

"devc" can't be NULL here so there is no need to check. Also I removed the "devc = NULL" assignment because devc is stored on stack so it's a no-op. Signed-off-by:

The functions release_and_free_resource() and snd_util_memhdr_free() test whether their argument is NULL and then return immediately. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software. Signed-off-by:

Like the previous fixes, the mixer accessors are converted to use usb_mixer_elem_list objects. In addition, the proper shutdown check are put in get and put callbacks. Signed-off-by: -

A few FTU mixer controls have the own value handling, so they have to be rewritten to follow the support for resume callbacks. This ended up in a fair amount of refactoring. Its own struct is now removed, instead the values are embedded in kctl private_value totally. Signed-off-by: -

The changes at this time are a bit more wider than previous ones. Firstly, the NI controls didn't cache the values, so I had to implement the caching. It's stored in bit 24 of private_value. In addition to that, the initial values have to be read from registers. Signed-off-by: -
