Let soc_dapm_mux_update_power() accept NULL as 'e' enum. It makes the code a bit more robust and, more importantly, let the calling mux force a disconnect of the output path if necessary. This is useful if the dapm elements following the mux must be off while updating the mux, to avoid glitches or force a (re)configuration.

So far the link names of the axg sound card was derived from the cpu name of the link. Since the dai link must be unique, it works as long as a device does not provide more than one cpu dai. However, the 'tohdmitx' does provide 2 dais used as cpu on codec-to-codec links Instead of cpu name, use the node name of the dai link. DT already enforce the uniqueness of this name Signed-off-by: Jerome Brunet <jbrunet@baylibre.com> Tested-by: Neil Armstrong <narmstrong@baylibre.com> Tested-by: Kevin Hilman <khilman@baylibre.com> Signed-off-by: Mark Brown <broonie@kernel.org>

soc-pcm.c has soc_pcm_components_close() but not have its open() side function. This kind of unbalance function is very unreadable. And, current error handling is not correct. Because it is using for_each_rtdcom() loop, we need to call soc_pcm_components_close() anyway even though CPU DAI .startup() failed. This patch adds soc_pcm_components_open(), and fixup error handling issue. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>

Current soc_bind_dai_link() is substituting rtd->codec_dais to codec_dais, and sets found DAI into it. But, it is a little bit un-readable / un-understandable to know detail of rtd, and it will make difficult to understand rtd->cpu_dais if Multi CPU was supported.

This file is implicitly relying on an instance of including module.h from <linux/acpi.h>. Ideally, header files under include/linux shouldn't be adding includes of other headers, in anticipation of their consumers, but just the headers needed for the header itself to pass parsing with CPP. The module.h is particularly bad in this sense, as it itself does include a whole bunch of other headers, due to the complexity of module support. Here, we make the include explicit, in order to allow the future removal of module.h from linux/acpi.h without causing build breakage.

Keeping the a pointer to the dai drivers is not necessary. It is not used by the hdmi_codec after the probe. Even if it was used, the 'struct snd_soc_dai_driver' can accessed through the 'struct snd_soc_dai' so keeping the pointer in the private data structure is not useful.

If the hdmi-codec is on a codec-to-codec link, the substream pointer it receives is completely made up by snd_soc_dai_link_event(). The pointer will be different between startup() and shutdown(). The hdmi-codec complains when this happens even if it is not really a problem. The current_substream pointer is not used for anything useful apart from getting the exclusive ownership of the device. Remove current_substream pointer and replace the exclusive locking mechanism with a simple variable and some atomic operations.

amplifier feedback is not modeled as being dependent on any active output. Even when there is no playback happening, parts of the graph, specifically the IV sense->speaker protection->output remains active and this prevents the DSP from entering low-power states. This patch suggest a machine driver level approach where the speaker pins are enabled/disabled dynamically depending on stream start/stop events. DPAM graph representations show the feedback loop is indeed disabled and low-power states can be reached.

For Spreadtrum audio platform driver, it need allocate a larger DMA buffer dynamically to copy audio data between userspace and kernel space, but that will increase the risk of memory allocation failure especially the system is under heavy load situation. To make sure the audio can work in this scenario, we usually reserve one region of memory to be used as a shared pool of DMA buffers for the platform component. So add of_reserved_mem_device_init_by_idx() function to initialize the shared pool of DMA buffers to be used by the platform component.
