Merge series "ASoC: soc-component: add snd_soc_component_xxx()" from Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>: Hi Mark These are v2 of snd_soc_component_compr_xxx() function patches. I think component related function should be implemented at soc-component.c, otherwise it is confusable to read. These are for it. v1 -> v2 - fixup function return timing on snd_soc_component_compr_get_params() snd_soc_component_compr_get_metadata() - use mutex at compr side on snd_soc_component_compr_get_caps() snd_soc_component_compr_get_codec_caps() snd_soc_component_compr_copy() Link: https://lore.kernel.org/r/878sb78ac4.wl-kuninori.morimoto.gx@renesas.com Kuninori Morimoto (12): ASoC: soc-component: add snd_soc_component_compr_open() ASoC: soc-component: add snd_soc_component_compr_free() ASoC: soc-component: add snd_soc_component_compr_trigger() ASoC: soc-component: add snd_soc_component_compr_set_params() ASoC: soc-component: add snd_soc_component_compr_get_params() ASoC: soc-component: add snd_soc_component_compr_get_caps() ASoC: soc-component: add snd_soc_component_compr_get_codec_caps() ASoC: soc-component: add snd_soc_component_compr_ack() ASoC: soc-component: add snd_soc_component_compr_pointer() ASoC: soc-component: add snd_soc_component_compr_copy() ASoC: soc-component: add snd_soc_component_compr_set_metadata() ASoC: soc-component: add snd_soc_component_compr_get_metadata() include/sound/soc-component.h | 22 +++ sound/soc/soc-component.c | 255 ++++++++++++++++++++++++++++++++ sound/soc/soc-compress.c | 263 ++++------------------------------ 3 files changed, 303 insertions(+), 237 deletions(-) -- 2.25.1

This series updates Sameer's patch to repartition the graph card binding schema and incorporate the OF graph schema. The schema was also mixing card node and DAI node properties, so I've split the DAI part (the 'port' node) into a separate schema. There's another problem that 'frame-master' and 'bitclock-master' have inconsistent types of boolean and phandle. Having the properties just point to the local or remote endpoint within an endpoint node is kind of pointless. We should have gone with just boolean, but looks like we already have several users. MMP OLPC is the one platform using boolean, but it happens to work because the properties are effectively ignored and CPU DAI as the master is the default.

The transmit phase register value is never cleared during hw params.

Sameer Pujar authored
There can be customized sound cards which are based on generic audio graph. In such cases most of the stuff is reused from generic audio graph. To facilitate this, refactor audio graph schema into multiple files and the base schema can be reused for specific sound cards. The graph card nodes and port nodes are separate entities, so they should be separate schemas.

Merge series "ASoC: Intel: catpt: Offload fixes and code optimization" from Cezary Rojewski <cezary.rojewski@intel.com>: First two of the series address bugs connected mainly to offload streams: - scenarios with very low buffer sizes: RESET_STREAM IPC timeouts - fix lp clock selection when switching between PAUSE <-> RESUME states: glitches on first offload when no additional stream is opened simultaneously Follow ups are: code reduction and optimization oriented patches. This has been foretold in: [PATCH v10 00/14] ASoC: Intel: Catpt - Lynx and Wildcat point https://www.spinics.net/lists/alsa-devel/msg116440.html Note: LPT power up/down sequences might get aligned with WPT once enough testing is done as capabilities are shared for both DSPs. First, optimize applying of user settings - prevent redundand calls from happening - and then as mentioned above, streamline power on/off sequence for LPT and WPT.

When compiled with CONFIG_HAVE_CLK, the kernel need to get provider for the clock API. This is usually selected by the platform and the sound drivers should not really care about this. However COMPILE_TEST is special and the platform required may not have been selected, leading to this type of error: > aiu-encoder-spdif.c:(.text+0x3a0): undefined reference to `clk_set_parent' Since we need a sane provider of the API with COMPILE_TEST, depends on COMMON_CLK.

Currently high-clock is selected on start of second stream onwards while low-clock is re-selected before stream actually leaves RESUME state i.e. PAUSE_STREAM call.

Playing with very low period sizes may lead to timeouts when awaiting RESET_STREAM reply for offload streams. This is caused by NOTIFY_POSITION appearing in the middle of trigger(stop). Stream is unprepared during trigger(stop) where PAUSE_STREAM IPC gets invoked. However, all data that is already mixed in DSP firmware's mixer stream will still be played regardless of the pause. For offload streams, this means possibility for another NOTIFY_POSITION to process. Keep these notifications in check by only handling them when stream is in prepared state.

Currently, pcm512x driver supports only I2S data format. This commit adds RJ, LJ, DSP_A and DSP_B as well. I don't expect regression WRT existing sound cards, because: * default value in corresponding register of pcm512x codec is 0 == I2S * existing in-tree sound cards with pcm512x codec are configured for I2S * i don't see how existing off-tree sound cards with pcm512x codec could be configured differently - it would not work * tested explicitly, that there is no regression with Raspberry Pi + sound card `sound/soc/bcm/hifiberry_dacplus.c` Signed-off-by: Kirill Marinushkin <kmarinushkin@birdec.com> Cc: Mark Brown <broonie@kernel.org> Cc: Takashi Iwai <tiwai@suse.com> Cc: Liam Girdwood <lgirdwood@gmail.com> Cc: Matthias Reichl <hias@horus.com> Cc: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Cc: Peter Ujfalusi <peter.ujfalusi@ti.com> Cc: alsa-devel@alsa-project.org Cc: linux-kernel@vger.kernel.org Reviewed-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Link: https://lore.kernel.org/r/20201115122306.18164-5-kmarinushkin@birdec.comSigned-off-by: Mark Brown <broonie@kernel.org>

I would like to describe the reasoning by quoting Peter Ujfalusi <peter.ujfalusi@ti.com> from his review of this patch series v1 [1]: > When you bind a link you will use set_fmt for the two sides to see if > they can agree, that both can support what has been asked. > > The pcm512x driver just saves the fmt and say back to that card: > whatever, I'm fine with it. But runtime during hw_params it can fail due > to unsupported bus format, which it actually acked to be ok. > > This is the difference. > > Sure, some device have constraint based on the fmt towards the hw_params > and it is perfectly OK to do such a checks and rejections or build > rules/constraints based on fmt, but failing hw_params just because > set_fmt did not checked that the bus format is not even supported is not > a nice thing to do.
