* ASoC: qcom: Fix NULL Dereference in asoc_qcom_lpass_cpu_platform_probe()Zichen Xie2024-10-071-0/+2
| | | | | | | | | | | | | A devm_kzalloc() in asoc_qcom_lpass_cpu_platform_probe() could possibly return NULL pointer. NULL Pointer Dereference may be triggerred without addtional check. Add a NULL check for the returned pointer.

* ASoC: qcom: Adjust issues in case of DT error in ↵Aleksandr Mishin2024-06-261-0/+4
| | | | | | | | | | | | | | | | | | | | asoc_qcom_lpass_cpu_platform_probe() If IORESOURCE_MEM "lpass-rxtx-cdc-dma-lpm" or "lpass-va-cdc-dma-lpm" resources is not provided in Device Tree due to any error, platform_get_resource_byname() will return NULL which is later dereferenced. According to sound/qcom,lpass-cpu.yaml, these resources are provided, but DT can be broken due to any error. In such cases driver must be able to protect itself, since the DT is external data for the driver. Adjust this issues by adding NULL return check.

* ASoC: qcom: lpass: Make asoc_qcom_lpass_cpu_platform_remove() return voidUwe Kleine-König2023-10-231-4/+1
| | | | | | | | | | | | | | | | | | The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. asoc_qcom_lpass_cpu_platform_remove() returned zero unconditionally. Make it return void instead and convert all users to struct platform_device::remove_new().

* ASoC: DT matching and header cleanupsMark Brown2023-10-101-24/+19
|\ | | | | | | | | | | | | | | | | | | | | Merge series from Rob Herring <robh@kernel.org>: This is a series is part of ongoing clean-ups related to device matching and DT related implicit includes. Essentially of_device.h has a bunch of implicit includes and generally isn't needed any nore except for of_match_device(). As we also generally want to get rid of of_match_device() as well, I've done that so we're not updating the includes twice.

* ASoC: Refactor non_legacy_dai_naming flagMark Brown2022-06-291-0/+1
|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Merge series from Charles Keepax <ckeepax@opensource.cirrus.com>: Historically, the legacy DAI naming scheme was applied to platform drivers and the newer scheme to CODEC drivers. During componentisation the core lost the knowledge of if a driver was a CODEC or platform, they were all now components. To continue to support the legacy naming on older platform drivers a flag was added to the snd_soc_component_driver structure, non_legacy_dai_naming, to indicate to use the new scheme and this was applied to all CODECs as part of the migration. However, a slight issue appears to be developing with respect to this flag being opt in for the non-legacy scheme, which presumably we want to be the primary scheme used. Many codec drivers appear to forget to include this flag: grep -l -r "snd_soc_component_driver" sound/soc/codecs/*.c | xargs grep -L "non_legacy_dai_naming" | wc 48 48 556 Whilst in many cases the configuration of the DAIs themselves will cause the core to apply the new scheme anyway, it would seem more sensible to change the flag to legacy_dai_naming making the new scheme opt out. This patch series migrates across to such a scheme.

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>

I noticed that it casts away const from the driver data from DT. That's not great but fixing it is a little more involved. I'll get to it later. There's also some questionable clk_get() usage that should probably be clk_get_optional(). For now this should help a little.

* ASoC: qcom: lpass-cpu: Make I2S SD lines configurableStephan Gerhold2020-05-051-46/+150
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The LPASS hardware allows configuring the MI2S SD lines to use when playing/recording audio. However, at the moment the lpass-cpu driver has SD0 hard-coded for mono/stereo (or additional fixed SD lines for more channels). For weird reasons there seems to be hardware that uses one of the other SD lines for mono/stereo. For example, some Samsung devices use an external Speaker amplifier connected to Quaternary MI2S. For some reason, the SD line for audio playback was connected to SD1 rather than SD0. (I have no idea why...) At the moment, the lpass-cpu driver cannot be configured to work for the Speaker on these devices. The q6afe driver already allows configuring the MI2S SD lines through the "qcom,sd-lines" device tree property, but this works only when routing audio through the ADSP. This commit adds a very similar configuration for the lpass-cpu driver. It is now possible to add additional subnodes to the lpass device in the device tree, to configure the SD lines for playback and/or capture. E.g. for the Samsung devices mentioned above: &lpass { dai@3 { reg = <MI2S_QUATERNARY>; qcom,playback-sd-lines = <1>; }; }; qcom,playback/capture-sd-lines takes a list of SD lines (0-3) in the same format as the q6afe driver. (The difference here is that q6afe has separate DAIs for playback/capture, while lpass-cpu has one for both...) For backwards compatibility with older device trees, the lpass-cpu driver defaults to LPAIF_I2SCTL_MODE_8CH if the subnode for a DAI is missing. This is equivalent to the previous behavior: Up to 8 channels can be configured, and SD0/QUAT01 will be chosen when setting up a stream with fewer channels. This allows the speaker to work on Samsung MSM8916 devices that use an external speaker amplifier.
