Request for help: How to upgrade a sound driver from kernel 4.14 to 6.6
by Steve Broshar 10 Jun '25

10 Jun '25

I have an audio driver/module that builds for kernel 4.14, but not for 6.6 due to changes in the kernel API.I find that API types (structs) and functions have been removed or changed, but IDK how to modify my code to use the updated API. Further, some of the changes seem less than clean. For example, in a couple places struct fields have been removed, but comments that used to precede the fields are still there such the comments are clearly no longer relevant and are therefore confusing. I have to wonder how many comments are out-of-date. My ask is for help fixing my code. I don't expect you to fix directly, but I need to know how to go about figuring out how to fix it. What changed in the API? Is there an upgrade guide/info? I am going to include more than a little info. I realize that it might be overwhelming. But, I fear that I try to reduce the info too much it will not convey the relevant context. I'll start with my analysis of my compiler errors that I get. Seems that the struct snd_soc_codec and struct snd_soc_codec_driver were removed. Seems that snd_soc_register_codec() and snd_soc_unregister_codec() were removed. What replaces these things? What do I need to change to accommodate the removal of these? FYI, here are my compiler errors: <build-errors> $ make -C ../../..

Many of these devices support SPI interface as well. So I thought I will make library and I2C interface file. But currently SPI support is not added in the driver.

But, in our case, codec chip has some GPIO pins which are specific to the codec. We do not intend to expose to the other kernel subsystem. It is more of codec chip configuration to use these GPIO pins as - for e.g. daisy-chain input, audio data output, PLL input clock source, interrupt, digital audio input(PDM) etc. Depending on the hardware connection, we need to configure some registers so that the pin can function as any one of the features which mentioned in the data sheet. More info in section "5 Pin Configuration and Functions" & "Table 7-70. Multifunction Pin Assignments" in the data sheet. https://www.ti.com/lit/ds/symlink/tac5212.pdf If it feels right, I can make this also as part of the dts configuration. Please suggest if I still need to expose this as gpiolib. > > > +static const char *const tac5x1x_slot_select_text[] = { > > + "Slot 0", "Slot 1", "Slot 2", "Slot 3", > > + "Slot 4", "Slot 5", "Slot 6", "Slot 7", > > + "Slot 8", "Slot 9", "Slot 10", "Slot 11", > > + "Slot 12", "Slot 13", "Slot 14", "Slot 15", > > + "Slot 16", "Slot 17", "Slot 18", "Slot 19", > > + "Slot 20", "Slot 21", "Slot 22", "Slot 23", > > + "Slot 24", "Slot 25", "Slot 26", "Slot 27", > > + "Slot 28", "Slot 29", "Slot 30", "Slot 31", > > +}; > > TDM slot control would usually be done via set_tdm_slot().

[PATCH v4 0/5] Add DisplayPort sound support for Fairphone 5 smartphone
by Luca Weiss 10 Jun '25

10 Jun '25

Add the necessary sound card bits and some dts additions to enable sound over DisplayPort-over-USB-C, e.g. to a connected TV or monitor. The UCM files can be found here: https://gitlab.postmarketos.org/postmarketOS/pmaports/-/tree/master/device/… This series - in spirit - depends on the series enabling DisplayPort in the first place, but can land pretty independently, especially the ASoC bits: https://lore.kernel.org/linux-arm-msm/20250312-fp5-pmic-glink-dp-v2-0-a5592… The ASoC bits depend on the patches for USB audio offloading merged through Greg's tree so this cannot easily be applied for v6.16 through the sound tree. Either it waits for v6.17 or also goes through Greg's tree. Signed-off-by: Luca Weiss <luca.weiss(a)fairphone.com> --- Changes in v4: - Use "sm4250" for qcom,qrb4210-rb2-sndcard (Srinivas) - Expand cover letter to mention dependencies for ASoC patches - Pick up tags - Link to v3: https://lore.kernel.org/r/20250425-fp5-dp-sound-v3-0-7cb45180091b@fairphone… Changes in v3: - Simplify return qcom_snd_wcd_jack_setup in machine driver - Pick up tags - Link to v2: https://lore.kernel.org/r/20250418-fp5-dp-sound-v2-0-05d65f084b05@fairphone… Changes in v2: - Revamp series based on comments on v1, doesn't have much too much in common anymore - Use sm8250 instead of sc8280xp sndcard file, so port other required changes from sc8280xp.c to sm8250.c - This also changes the sound card compatible to from qcom,qcm6490-sndcard to fairphone,fp5-sndcard - Link to v1: https://lore.kernel.org/r/20240809-fp5-dp-sound-v1-0-d7ba2c24f6b9@fairphone… --- Luca Weiss (5): ASoC: dt-bindings: qcom,sm8250: Add Fairphone 5 sound card ASoC: qcom: sm8250: set card driver name from match data ASoC: qcom: sm8250: add DisplayPort Jack support ASoC: qcom: sm8250: Add Fairphone 5 soundcard compatible arm64: dts: qcom: qcm6490-fairphone-fp5: Add DisplayPort sound support .../devicetree/bindings/sound/qcom,sm8250.yaml | 1 + arch/arm64/boot/dts/qcom/qcm6490-fairphone-fp5.dts | 31 ++++++++++++++++++++++ sound/soc/qcom/sm8250.c | 27 ++++++++++--------- 3 files changed, 47 insertions(+), 12 deletions(-) --- base-commit: f819a667fa466d3b96b542b147053b6873f18ea1 change-id: 20240809-fp5-dp-sound-b3768f3019bd Best regards, -- Luca Weiss <luca.weiss(a)fairphone.com>
