* ASoC: audio-graph: respawn Platform SupportKuninori Morimoto2021-09-011-0/+6
| | | | | | | | | | | | | | | | | | | commit 63f2f9cceb09f8 ("ASoC: audio-graph: remove Platform support") removed Platform support from audio-graph, because it doesn't have "plat" support on DT (simple-card has). But, Platform support is needed if user is using snd_dmaengine_pcm_register() which adds generic DMA as Platform. And this Platform dev is using CPU dev. Without this patch, at least STM32MP15 audio sound card is no more functional (v5.13 or later). This patch respawn Platform Support on audio-graph again.

* ASoC: simple-card-utils: Avoid over-allocating DLCsSamuel Holland2021-08-051-2/+2
| | | | | | | | | | | | | | The allocation of the DAI link components (DLCs) passed the wrong pointer to sizeof.

* ASoC: audio-graph: remove Platform supportKuninori Morimoto2021-04-201-6/+0
| | | | | | | | | | | | | | | | | | | | | Platform was one of mandatory component on ASoC before, and audio-graph-card was assuming that CPU and Platform were same driver. But it is no longer mandatory on ASoC. Current ASoC will just ignore if Platform and CPU were same or doplicated component. Of course ASoC is supporting Platform, but current audio-graph-card doesn't support detecting it from DT. This means current audio-graph-card operation for Platform so far is 100% useless. This patch removes it. We can respawn it when we need it.

| | | | | | | | | | | | | | | | | | The DAI counting code doesn't propagate errors when the number of maximum links is exceeded, which causes subsequent initialization code to continue to run and that eventually leads to memory corruption with the code trying to access memory that is out of bounds. Fix this by propagating errors when the maximum number of links is reached, which ensures that the driver fails to load and prevents the memory corruption.

* ASoC: simple-card: fix possible uninitialized single_cpu local variableKrzysztof Kozlowski2021-04-072-2/+2
| | | | | | | | | | | | | | | | The 'single_cpu' local variable is assigned by asoc_simple_parse_dai() and later used in a asoc_simple_canonicalize_cpu() call, assuming the entire function did not exit on errors. However the first function returns 0 if passed device_node is NULL, thus leaving the variable uninitialized and reporting success.

A new control layer registration is introduced which allows to run additional operations on top of the elementary ALSA sound controls. A new control access group (three bits in the access flags) was introduced to carry the LED group information for the sound controls. The low-level sound drivers can just mark those controls using this access group. This information is not exported to the user space, but user space can manage the LED sound control associations through sysfs (last patch) per Mark's request. It makes things fully configurable in the kernel and user space (UCM). The actual state ('route') evaluation is really easy (the minimal value check for all channels / controls / cards). If there's more complicated logic for a given hardware, the card driver may eventually export a new read-only sound control for the LED group and do the logic itself. The new LED trigger control code is completely separated and possibly optional (there's no symbol dependency). The full code separation allows eventually to move this LED trigger control to the user space in future. Actually it replaces the already present functionality in the kernel space (HDA drivers) and allows a quick adoption for the recent hardware (ASoC codecs including SoundWire). snd_ctl_led 24576 0 The sound driver implementation is really easy: 1) call snd_ctl_led_request() when control LED layer should be automatically activated / it calls module_request("snd-ctl-led") on demand / 2) mark all related kcontrols with SNDRV_CTL_ELEM_ACCESS_SPK_LED or SNDRV_CTL_ELEM_ACCESS_MIC_LED Link: https://lore.kernel.org/r/20210317172945.842280-1-perex@perex.cz Signed-off-by: Takashi Iwai <tiwai@suse.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit 1e30f642cf29 ("ASoC: simple-card-utils: Fix device module clock"). The original patch ended up breaking following platform, which depends on set_sysclk() to configure internal PLL on wm8904 codec and expects simple-card-utils to not update the MCLK rate. - "arch/arm64/boot/dts/freescale/fsl-ls1028a-kontron-sl28-var3-ads2.dts" It would be best if codec takes care of setting MCLK clock via DAI set_sysclk() callback.

| | | | | | | | | | | | | | | | If "clocks = <&xxx>" is specified from the CPU or Codec component device node, the clock is not getting enabled. Thus audio playback or capture fails. Fix this by populating "simple_dai->clk" field when clocks property is specified from device node as well. Also tidy up by re-organising conditional statements of parsing logic.
