* staging: most: remove multiple blank linesChristian Gromm2015-10-251-1/+0Star
| | | | | | | This patch removes the usage of multiple blank lines from driver modules. Signed-off-by: Christian Gromm <christian.gromm@microchip.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* Staging: most: Remove exceptional & on function nameShraddha Barke2015-10-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | In this file, function names are otherwise used as pointers without &. A simplified version of the Coccinelle semantic patch that makes this change is as follows: // <smpl> @r@ identifier f; @@ f(...) { ... } @@ identifier r.f; @@ - &f + f // </smpl> Signed-off-by: Shraddha Barke <shraddha.6596@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* staging: most: fix pcm_write input/output errorChristian Gromm2015-09-291-6/+11
| | | | | | | | | This patch keeps the process from sleeping after the PCM middle layer has stopped playback by calling the pcm trigger callback. The patch is needed to prevent aplay from causing a pcm_write Input/Output error.

* staging: most: remove audio resolution format checkChristian Gromm2015-09-291-2/+1Star
| | | | | | | | This patch removes the audio format cross-check, because the definitions are not compatible. Signed-off-by: Christian Gromm <christian.gromm@microchip.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* staging: most: fix style problemsChristian Gromm2015-09-291-3/+3
| | | | | | | This patch simply corrects style violations. Signed-off-by: Christian Gromm <christian.gromm@microchip.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* staging: most: move initialization codeChristian Gromm2015-09-291-18/+10Star
| | | | | | | | This pathch moves the initialization of the PCM middle layer hardware parameters to function audio_set_hw_params(). Signed-off-by: Christian Gromm <christian.gromm@microchip.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* staging: most: rename functionChristian Gromm2015-09-291-2/+2
| | | | | | | | | This patch renames the function audio_set_pcm_format(). Since the function doesn't only set the PCM format anymore and to guard against misunderstandings, its name needs to be changed. Signed-off-by: Christian Gromm <christian.gromm@microchip.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* staging: most: add missing channel initializationChristian Gromm2015-09-291-0/+2
| | | | | | | | This patch adds missing initialization of channel count for 8-bit mono audio resolution. Signed-off-by: Christian Gromm <christian.gromm@microchip.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* staging: most: purge unecessary variableChristian Gromm2015-09-291-4/+1Star
| | | | | | | | This patch purges a temp. variable to store the functions return value. Since the content is never being evaluated, it can safely be removed. Signed-off-by: Christian Gromm <christian.gromm@microchip.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* staging: most: squash AIM soundChristian Gromm2015-09-291-14/+0Star
| | | | | | | | This patch removes debug messages and prevents the sound AIM from being noisy in kernel log. Signed-off-by: Christian Gromm <christian.gromm@microchip.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* staging: most: make hardware parameters channel exclusiveChristian Gromm2015-09-291-32/+36
| | | | | | | | | Since the PCM interface's hardware parameters are channel/substream exclusive, the struct snd_pcm_hardware needs to be embedded in the channel structure. Signed-off-by: Christian Gromm <christian.gromm@microchip.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* staging: most: include vendor in audio card's shortnameChristian Gromm2015-09-291-1/+1
| | | | | | | | This patch adds Microchip as vendor to the audio card's shortname to be displayed, when playback and capture devices are queried. Signed-off-by: Christian Gromm <christian.gromm@microchip.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* staging: most: add multi channel support to sound AIMChristian Gromm2015-09-291-2/+25
| | | | | | | | | This patch adds 5.1 surround configuration with subbuffer cross-check, when establishing a link to the core. For the sake of simplicity, only one specific channel configuration is allowed. Signed-off-by: Christian Gromm <christian.gromm@microchip.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* staging: most: add fair buffer distributionChristian Gromm2015-09-291-1/+2
| | | | | | | | | | | This patch ensures a fair distribution of buffers, when two AIMs share a single channel. The AIMs then won't be able to use more than half of all pre-allocated buffers of the linked channel. However, in case the channel is not shared, the AIM can exclusively use all available buffers.

* staging: most: fix channel operation in multi-aim contextChristian Gromm2015-09-291-2/+3
| | | | | | | | | This patch fixes the opening and closing process of a physical channel when used by different AIMs. Signed-off-by: Andrey Shvetsov <andrey.shvetsov@k2l.de> Signed-off-by: Christian Gromm <christian.gromm@microchip.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* staging: most: make functions staticSudip Mukherjee2015-09-131-2/+3
| | | | | | | | split_arg_list() and audio_set_pcm_format() are being called from the same file and is not referenced from outside, so make them as static. Signed-off-by: Sudip Mukherjee <sudip@vectorindia.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

* Staging: most: add MOST driver's aim-sound moduleChristian Gromm2015-07-243-0/+774
This patch adds the aim-sound module of the MOST driver to the kernel's driver staging area. This module is part of the MOST driver and handles user space interaction by means of ALSA devices. This patch is needed in order to have access to MOST synchronous data through ALSA devices.
