ASoC: mediatek: mt8195: Add platform entry for ETDM1_OUT_BE dai link

2024-07-05T07:37:54Z

[ Upstream commit 282a4482e198e03781c152c88aac8aa382ef9a55 ] Commit e70b8dd26711 ("ASoC: mediatek: mt8195: Remove afe-dai component and rework codec link") removed the codec entry for the ETDM1_OUT_BE dai link entirely instead of replacing it with COMP_EMPTY(). This worked by accident as the remaining COMP_EMPTY() platform entry became the codec entry, and the platform entry became completely empty, effectively the same as COMP_DUMMY() since snd_soc_fill_dummy_dai() doesn't do anything for platform entries. This causes a KASAN out-of-bounds warning in mtk_soundcard_common_probe() in sound/soc/mediatek/common/mtk-soundcard-driver.c: for_each_card_prelinks(card, i, dai_link) { if (adsp_node && !strncmp(dai_link->name, "AFE_SOF", strlen("AFE_SOF"))) dai_link->platforms->of_node = adsp_node; else if (!dai_link->platforms->name && !dai_link->platforms->of_node) dai_link->platforms->of_node = platform_node; } where the code expects the platforms array to have space for at least one entry. Add an COMP_EMPTY() entry so that dai_link->platforms has space.

ASoC: mediatek: mt8183-da7219-max98357: Fix kcontrol name collision

2024-07-05T07:37:49Z

[ Upstream commit 97d8613679eb53bd0c07d0fbd3d8471e46ba46c1 ] Since "Headphone Switch" kcontrol name has already been used by da7219, rename the control name from "Headphone" to "Headphones" to prevent the colision. Also, this change makes kcontrol name align with the one in mt8186-mt6366-da7219-max98357.c.

ASoC: mediatek: Assign dummy when codec not specified for a DAI link

2024-05-30T07:44:44Z

[ Upstream commit 5f39231888c63f0a7708abc86b51b847476379d8 ] MediaTek sound card drivers are checking whether a DAI link is present and used on a board to assign the correct parameters and this is done by checking the codec DAI names at probe time. If no real codec is present, assign the dummy codec to the DAI link to avoid NULL pointer during string comparison.

Merge tag 'asoc-fix-v6.8-merge-window' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus

2024-01-16T16:37:17Z

ASoC: Fixes for v6.8 A bunch of small fixes that come in during the merge window, mainly fixing issues from some core refactoring around dummy components that weren't detected until things reached mainline. The TAS driver changes are a little larger than normal for a device ID addition due to some shuffling around of where things are registered and DT updates but aren't really any more substantial than normal.

ASoC: mediatek: sof-common: Add NULL check for normal_link string

2024-01-11T15:42:09Z

It's not granted that all entries of struct sof_conn_stream declare a `normal_link` (a non-SOF, direct link) string, and this is the case for SoCs that support only SOF paths (hence do not support both direct and SOF usecases). For example, in the case of MT8188 there is no normal_link string in any of the sof_conn_stream entries and there will be more drivers doing that in the future. To avoid possible NULL pointer KPs, add a NULL check for `normal_link`.

ASoC: mediatek: mt8195: Remove afe-dai component and rework codec link

2024-01-10T13:31:56Z

Remove the extra 'mt8195-afe-pcm-dai' component, register the DAI drivers to the main AFE component, and rework the DAI linking between the headset codec (RT5682/RT5682S) and the TDM interface in the probe function to stop assigning name, relying on the of_node of the codec. Also replace the COMP_DUMMY codec entry with a COMP_EMPTY for the ETDM2_IN and remove it entirely from ETDM1_OUT to fix the registration flow for this sound card. While at it, since we also need to swap the codec init function from ETDM2_IN to ETDM1_OUT, remove the static assignment of both `ops` and `init` for both, as we now assign these dynamically during probe.

ASoC: mediatek: mt8192: Check existence of dai_name before dereferencing

2024-01-08T20:58:28Z

Following commit 13f58267cda3 ("ASoC: soc.h: don't create dummy Component via COMP_DUMMY()"), the dai_name field is only populated for dummy components after the card is registered. This causes a null pointer dereference in the mt8192-mt6359 sound card driver's probe function when searching for a dai_name among all the card's dai links. Verify that the dai_name is non-null before passing it to strcmp. While at it, also check that there's at least one codec.

Merge tag 'asoc-v6.8' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus

2024-01-08T07:18:02Z

ASoC: Updates for v6.8 This is a relatively quiet release, there's a lot of driver specific changes and the usual high level of activity in the SOF core but the one big core change was Mormioto-san's work to support more N:M CPU:CODEC mapping cases. Highlights include: - Enhanced support for N:M CPU:CODEC mappings in the core and in audio-graph-card2. - Support for falling back to older SOF IPC versions where firmware for new versions is not available. - Support for notification of control changes generated by SOF firmware with IPC4. - Device tree support for describing parts of the card which can be active over suspend (for very low power playback or wake word use cases). - ACPI parsing support for the ES83xx driver, reducing the number of quirks neede for x86 systems. - Support for more AMD and Intel systems, NXP i.MX8m MICFIL, Qualcomm SM8250, SM8550, SM8650 and X1E80100. - Removal of Freescale MPC8610 support, the SoC is no longer supported by Linux.

ASoC: mediatek: mt8186: fix AUD_PAD_TOP register and offset

2023-12-29T17:08:18Z

AUD_PAD_TOP widget's correct register is AFE_AUD_PAD_TOP , and not zero. Having a zero as register, it would mean that the `snd_soc_dapm_new_widgets` would try to read the register at offset zero when trying to get the power status of this widget, which is incorrect.
