ASoC: topology: Move v4 manifest header data structures to uapi

2018-06-01T17:09:13+00:00

Topology manifest v4 is still part of the ABI. Move its data structures
into the uapi header file.

No functional change.

ASoC: topology: Add definitions for mclk_direction values

2018-04-16T16:52:31+00:00

Current comment makes not clear the direction of mclk. Previously, similar
description caused a misunderstanding for bclk_master and fsync_master.

This commit solves the potential confusion the same way it is solved for
bclk_master and fsync_master.

ASoC: topology: Add missing clock gating parameter when parsing hw_configs

2018-04-16T16:52:26+00:00

Clock gating parameter is a part of `dai_fmt`. It is supported by
`alsa-lib` when creating a topology binary file, but ignored by kernel
when loading this topology file.

After applying this commit, the clock gating parameter is not ignored any
more. This solution is backwards compatible. The existing behaviour is
not broken, because by default the parameter value is 0 and is ignored.

snd_soc_tplg_hw_config.clock_gated = 0 => no effect
snd_soc_tplg_hw_config.clock_gated = 1 => SND_SOC_DAIFMT_GATED
snd_soc_tplg_hw_config.clock_gated = 2 => SND_SOC_DAIFMT_CONT

For example, the following config, based on
alsa-lib/src/conf/topology/broadwell/broadwell.conf, is now supported:

~~~~
SectionHWConfig."CodecHWConfig" {
        id "1"
        format "I2S"            # physical audio format.
        pm_gate_clocks "true"   # clock can be gated
}

SectionLink."Codec" {

        # used for binding to the physical link
        id "0"

        hw_configs [
                "CodecHWConfig"
        ]

        default_hw_conf_id "1"
}
~~~~

ASoC: topology: Fix bclk and fsync inversion in set_link_hw_format()

2018-04-16T16:52:16+00:00

The values of bclk and fsync are inverted WRT the codec. But the existing
solution already works for Broadwell, see the alsa-lib config:

`alsa-lib/src/conf/topology/broadwell/broadwell.conf`

This commit provides the backwards-compatible solution to fix this misuse.

License cleanup: add SPDX license identifier to uapi header files with a license

2017-11-02T10:20:11+00:00

Many user space API headers have licensing information, which is either
incomplete, badly formatted or just a shorthand for referring to the
license under which the file is supposed to be.  This makes it hard for
compliance tools to determine the correct license.

Update these files with an SPDX license identifier.  The identifier was
chosen based on the license information in the file.

GPL/LGPL licensed headers get the matching GPL/LGPL SPDX license
identifier with the added 'WITH Linux-syscall-note' exception, which is
the officially assigned exception identifier for the kernel syscall
exception:

   NOTE! This copyright does *not* cover user programs that use kernel
   services by normal system calls - this is merely considered normal use
   of the kernel, and does *not* fall under the heading of "derived work".

This exception makes it possible to include GPL headers into non GPL
code, without confusing license compliance tools.

Headers which have either explicit dual licensing or are just licensed
under a non GPL license are updated with the corresponding SPDX
identifier and the GPLv2 with syscall exception identifier.  The format
is:
        ((GPL-2.0 WITH Linux-syscall-note) OR SPDX-ID-OF-OTHER-LICENSE)

SPDX license identifiers are a legally binding shorthand, which can be
used instead of the full boiler plate text.  The update does not remove
existing license information as this has to be done on a case by case
basis and the copyright holders might have to be consulted. This will
happen in a separate step.

This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.  See the previous patch in this series for the
methodology of how this patch was researched.

ASoC: topology: ABI - Rename be_dai_elems to dai_elems in manifest

2016-11-09T14:46:09+00:00

User space uses this field to count physical DAIs, not only BE DAIs since
users may not use DPCM. So we rename this field from be_dai_elems to
dai_elems.

This change is backward compatible, because it does not change the layout
of the struct or data type.

ASoC: topology: ABI - Add voice wake up flag for DAI links

2016-11-04T17:36:39+00:00

Add a new flag bit SND_SOC_TPLG_LNK_FLGBIT_VOICE_WAKEUP to link flags.
If a link is used for voice wake up, users can set this flag bit and
topology will set the link's 'ignore_suspend' to true.

This ABI update is backward compatible.

ASoC: topology: ABI - Rename struct and type for physical DAIs

2016-11-04T17:26:42+00:00

Rename the ABI struct and type because they are for configuring physical
DAIs, not only backend DAIs since users may not need DPCM:
- Rename struct snd_soc_tplg_be_dai to snd_soc_tplg_dai.
- Rename type SND_SOC_TPLG_TYPE_BE_DAI to SND_SOC_TPLG_TYPE_DAI.

This code refactoring is backward compatible because:
- Both layout of the struct and type value has no change. Kernel can
  find the same type value and map to same data layout.
- This struct is not in ABI v4 at all. Now the user space uses ABI v4.
