This code tends to use unsigned variables by default and it causes signedness bugs when we use negative variables for error handling. The "i" and "j" variables are used to iterated over small positive values and so they should be type "int". The "len" variable doesn't *need* to be signed but it should be signed to make the code easier to read and audit. Signed-off-by:

This commit adds MIDI functionality with an assumption of 'if the device has MIDI comformant data channels in its stream formation, the device has one MIDI port'. When no streams have already started, MIDI functionality starts stream with current sampling rate. When MIDI functionality has already starts some streams and PCM functionality is going to start streams at different sampling rate, this driver stops streams once and changes sampling rate, then restarts streams for both PCM/MIDI substreams.

In previous commit, a support for transmitted packets is added. This commit add a support for capturing PCM samples. When any streams are already started, this driver should not change sampling rate of the device, thus this commit also adds a restriction of sampling rate in this situation. Signed-off-by:

Previous commit adds support for some devices which can capture PCM samples. These devices transmit AMDTP stream in non-blocking mode. This commit adds functionality to handle AMDTP incoming stream. OXFW seems to have two quirks: - Transmits packets with non-zero dbc in its beginning - Transmits packets with wrong values in syt field For the first quirk, this commit adds CIP_SKIP_INIT_DBC_CHECK flag for incoming stream to skip first check of dbc. For the second quirk, this commit doesn't add duplex stream which Fireworks/BeBoB drivers use. So OXFW driver generates syt value for outgoing stream. Here are examples of a sequence of packets transmitted by Behringer F-Control Audio 202. There are differences between sequences of syt value when OXFW driver transfers outgoing stream or not. When driver gives no outgoing stream: Index Payload CIP_Header_0 CIP_Header_1 38 14 00020092 900103D1 39 12 00020098 900102FF 40 12 0002009D 9001027F 41 14 000200A2 90010396 42 14 000200A8 900102E8 43 12 000200AE 90010219 44 14 000200B3 90010331 45 12 000200B9 9001025F 46 14 000200BE 90010376 47 12 000200C4 900102A1 00 12 000200C9 9001023E 01 14 000200CE 90010358 02 12 000200D4 90010289 03 16 000200D9 900103A3 04 12 000200E0 900102DD 05 14 000200E5 900103F1 06 12 000200EB 90010335 07 12 000200F0 90010263 08 14 000200F5 9001037C 09 12 000200FB 900102AE When driver gives outgoing stream: Index Payload CIP_Header_0 CIP_Header_1 38 12 000200BD 900104A8 39 14 000200C2 900104A8 40 12 000200C8 900104AC 41 14 000200CD 900104A9 42 12 000200D3 900104B1 43 14 000200D8 900104A8 44 12 000200DE 900104AA 45 14 000200E3 900104A9 46 14 000200E9 900104AE 47 12 000200EF 900104A8 00 14 000200F4 900104AD 01 12 000200FA 900104A7 02 14 000200FF 900104A9 03 12 00020005 900104A9 04 14 0002000A 900104B1 05 12 00020010 900104AA 06 14 00020015 900104AD 07 12 0002001B 900104A7 08 14 00020020 900104AC 09 12 00020026 900104A7 Signed-off-by:

Some devices produced by Behringer/Mackie are based on OXFW970/971. This commit adds support for them. Additionally, this commit changes the way to name card with some information in config rom. Ids of some Mackie(Loud) models are not identified, therefore this commit applies name detection for these models. The devices support capture/playback of PCM-samples and some of them supports capture/playback of MIDI messages. These functionalities are implemented by followed commits. Signed-off-by:

In past commit, this driver can keep stream formations for each sampling rate. So its stream functionality can decide stream formations with given some parameters. This commit moves related codes from PCM functionality to stream functionality. Furthermore, to set stream format correctly, this commit uses AV/C Stream Format Information command instead of AV/C Input/Output Plug Signal Format command. Signed-off-by:

In previous commit, this driver can get to know stream formations at each supported sampling rates. This commit uses it to make PCM rules/constraints and obsoletes hard-coded rules/constraints. For this purpose, this commit adds 'struct snd_oxfw_stream_formation' and snd_oxfw_stream_parse_format() to parse data channel formation of data block. According to datasheet of OXFW970/971, they support 32.0kHz to 196.0kHz. As long as developers investigate, some devices are confirmed to have several formats for the same sampling rate.

OXFW970/971 may supports AV/C Stream Format Information Specification 1.1 Working Draft (Apr 2005, 1394TA). By using this command, drivers can get to know stream formations which device supports. This commit adds 'EXTENDED STREAM FORMAT INFORMATION' command. This command has two subfunctions, 'SINGLE' and 'LIST'. Drivers can use 'SINGLE' subfunction to know/set current formation of AMDTP stream, Drivers can use 'LIST' subfunction to know an available formation of AMDTP stream in a certain sampling rate. But some devices don't implement the 'LIST' subfunction. So this commit uses an assumption that 'if they don't implement it, they don't change stream formation depending on current each sampling rate'. With this assumption, this driver generates formations for such devices by: 1.getting current formation by SINGLE subfunction 2.getting supported sampling rates 3.applying current formation for all of supported sampling rates Followed commit implements a parser of this format information.

This is a preparation for more models. In following commit, members of 'struct snd_card' related to name becomes to consists of vendor and model strings in device's config-rom. Current supported devices also has strings in their config rom, but the strings are too long to name sound card, thus this driver still keep hard-coded vendor and model names for them. Signed-off-by:

This commit allows this driver to handle devices with non SYT-Match sampling clock source. When sampling clock source is SYT-Match mode, devices handle 'presentation timestamp' in received packets and generates sampling clock according to the information. In this case, driver is synchronization master and must transfer correct value in SYT field of each packets in outgoing stream, then the outgoing stream is a master stream. On the other hand, non SYT-Match mode, devices do this. So drivers must pick up the value in SYT field of incoming packets and use the value for outgoing stream. Currently firewire-lib module achieve this work. Furthermore, without SYT-Match and internal clock source, the sampling rate should be fixed for the other devices connected to the handled device. This commit add a restriction of sampling rate at this situation. With these implementations, this driver has no need to set clock source. This commit remove set function. Signed-off-by:

This commit adds support for AMDTP in-stream. As a result, Dice driver supports full duplex streams with synchronization. AMDTP can transfer timestamps in its packets. By handling the timestamp, devices can synchronize to the other devices or drivers on the same bus. When Dice chipset is 'enabled', it starts streams with correct settings. This 'enable' register is global, thus, when a stream is started to run, an opposite stream can't start unless turning off 'enable'. Therefore a pair of streams must be running. This causes a loss of CPU usage when single stream is needed for neither playbacking or capturing. This commit assumes that playback-only models also have a functionality to transmit stream for delivering timestamps. Currently, sampling clock source is restricted to SYT-Match mode. This is improved in followed commit. I note that at SYT-Match mode, Dice can select from 4 streams for synchronization but this driver uses the 1st stream only for simplicity. Signed-off-by:

Merge tag 'asoc-v3.19' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Updates for v3.19 Lots and lots of changes this time around, the usual set of driver updates and a huge bulk of cleanups from Lars-Peter. Probably the most interesting thing for most users is the Intel driver updates which will (with some more machine integration work) enable support for newer x86 laptops. - Conversion of AC'97 drivers to use regmap, bringing us closer to the removal of the ASoC level I/O code. - Clean up a lot of old drivers that were open coding things that have subsequently been implemented in the core. - Some DAPM performance improvements. - Removal of the now seldom used CODEC mutex. - Lots of updates for the newer Intel SoC support, including support for the DSP and some Cherrytrail and Braswell machine drivers. - Support for Samsung boards using rt5631 as the CODEC. - Removal of the obsolete AFEB9260 machine driver. - Driver support for the TI TS3A227E headset driver used in some Chrombeooks.
