by Liam Girdwood 14 Jun '17

14 Jun '17

The alsa-lib topology parser is missing some fields for certain objects that are part of the ABI. This patch adds the missing fields to the parser.

[alsa-devel] [PATCH 0/2] ALSA: pcm: remove unused local commands
by Takashi Sakamoto 14 Jun '17

14 Jun '17

Hi, A callback of 'struct snd_pcm_ops.ioctl' is internally used for ALSA pcm core to communicate to each drivers for some purposes; e.g. ask the size of FIFO in handled devices. However, in 'include/sound/pcm.h', there're some commands for the callback, which has never been used. This commit removes the unused commands to prevent developers from undocumented and unreferenced features.

[alsa-devel] [PATCH v4] ASoC: sgtl5000: add avc support
by Richard Leitner 14 Jun '17

14 Jun '17

The sgtl5000 features an automatic volume control block (AVC), which reduces loud signals and amplifies low level signals for easier listening. This patch adds support for this AVC block to the driver. Apart from the "AVC Switch" control which enables the block following controls for the configuration of AVC are added: + AVC Threshold Volume: threshold where audio is compressed when the measured level is above or expanded when below + AVC Max Gain Volume: maximum gain which can be applied when the measured audio level is below threshold + AVC Hard Limiter Switch: when enabled the signal is limited to the programmed threshold. + AVC Integrator Response: response time of the integrator The AVC block is enabled and configured using the DAP_AVC_CTRL and DAP_AVC_THRESHOLD registers.

[alsa-devel] [PATCH] ASoC: rsnd: reduce confusable macro parameter magic
by Kuninori Morimoto 14 Jun '17

14 Jun '17

From: Kuninori Morimoto <kuninori.morimoto.gx(a)renesas.com> rsnd_dai_call() macro is using "priv" inside. Thus, if caller function doesn't have "priv" related operation, strange phenomenon occur which code is using "priv", but compiler indicates "unused variable 'priv'". From code point of view, it is not problem, but it is very confusable. This patch removes "priv" from rsnd_dai_call() macro, and adds "priv" on caller function.

[alsa-devel] [PATCH 0/5] ASoC: simple/graph card: use asoc_simple_card_of_parse_tdm()
by Kuninori Morimoto 14 Jun '17

Hi Mark These are not a big deal, but current simple/graph card drivers are using asoc_simple_dai's tx_slot_mask, rx_slot_mask, slots, slot_width directly to parse TDM. Encapsulation is one of simple card util's purpose. These are cleanup for it. Kuninori Morimoto (5): ASoC: simple-card-utils: add asoc_simple_card_of_parse_tdm() ASoC: simple-card: use asoc_simple_card_of_parse_tdm() ASoC: simple-scu-card: use asoc_simple_card_of_parse_tdm() ASoC: audio-graph-card: use asoc_simple_card_of_parse_tdm() ASoC: audio-graph-scu-card: use asoc_simple_card_of_parse_tdm() include/sound/simple_card_utils.h | 6 ++++++ sound/soc/generic/audio-graph-card.c | 12 ++---------- sound/soc/generic/audio-graph-scu-card.c | 6 +----- sound/soc/generic/simple-card.c | 10 ++-------- sound/soc/generic/simple-scu-card.c | 6 +----- 5 files changed, 12 insertions(+), 28 deletions(-) -- 1.9.1
