alsa-project/alsa-utils pull request #220 was edited from brentlu: Current alsatplg supports only cardinal clock source without m/n divider. Code in SOF ssp driver is ported here to implement the divider function. I tested the code on ADL brya device with following setting: MCLK: 19.2MHz BCLK: 3.072Mz (m 24 n 25) Request URL : https://github.com/alsa-project/alsa-utils/pull/220 Patch URL : https://github.com/alsa-project/alsa-utils/pull/220.patch Repository URL: https://github.com/alsa-project/alsa-utils

[PATCH v2 1/1] ASoC: dt-bindings: tlv320aic32x4: convert to DT schema format

Convert the binding to DT schema format. Since commit 514b044cba667 ("ASoC: tlv320aic32x4: Model PLL in CCF") clocks & clock-names = "mclk" is mandatory, it has been added to required properties as well. '#sound-dai-cells' is added for reference from simple-audio-card. Signed-off-by: Alexander Stein <alexander.stein(a)ew.tq-group.com> --- Changes in v2: * Rebased onto for-next of [1] * Add vendor prefix 'ti' to file name * Simplify 'reg' property * Removed description from 'reset-gpios' * Added reference to dai-common.yaml * Fixed node name in example There is no in-tree user for aic32x4-gpio-func, so I just converted the bindings to YAML and skipped introducing a dt-binding header for defining the constants.

[PATCH v4 00/13] Add support for IIO devices in ASoC
by Herve Codina 16 Jun '23

16 Jun '23

Several weeks ago, I sent a series [1] for adding a potentiometer as an auxiliary device in ASoC. The feedback was that the potentiometer should be directly handled in IIO (as other potentiometers) and something more generic should be present in ASoC in order to have a binding to import some IIO devices into sound cards. The series related to the IIO potentiometer device is already applied. This series introduces audio-iio-aux. Its goal is to offer the binding between IIO and ASoC. It exposes attached IIO devices as ASoC auxiliary devices and allows to control them through mixer controls. On my system, the IIO device is a potentiometer and it is present in an amplifier design present in the audio path. Compare to the previous iteration https://lore.kernel.org/linux-kernel/20230612122926.107333-1-herve.codina@b… This v4 series mainly: - Fixes headers inclusion - Removes unneeded variable initialization - Adds a missing error check - Fixes typos Best regards, Hervé [1] https://lore.kernel.org/linux-kernel/20230203111422.142479-1-herve.codina@b… [2] https://lore.kernel.org/linux-kernel/20230421085245.302169-1-herve.codina@b… Changes v3 -> v4 - Patches 1, 2 No changes. - Patches 3, 4, 5 Add 'Reviewed-by: Andy Shevchenko <andy.shevchenko(a)gmail.com>'. - Patch 6 (new in v4) Fix headers inclusion order. - Patch 7 (patch 6 in v3) Add a comment related to __must_be_array() Use __array[0] of *__array - Patch 8 (patch 7 in v3) Fix minmax.h inclusion order.
