[PATCH] ASoC: ops: Shift tested values in snd_soc_put_volsw() by +min
by Marek Vasut 19 May '22

While the $val/$val2 values passed in from userspace are always >= 0 integers, the limits of the control can be signed integers and the $min can be non-zero and less than zero. To correctly validate $val/$val2 against platform_max, add the $min offset to val first.

[PATCH] ALSA: usb-audio: Always apply the hw constraints for implicit fb sync
by Takashi Iwai 22 Apr '22

22 Apr '22

Since the commit 5a6c3e11c9c9 ("ALSA: usb-audio: Add hw constraint for implicit fb sync"), we apply the hw constraints for the implicit feedback sync to make the secondary open aligned with the already opened stream setup. This change assumed that the secondary open is performed after the first stream has been already set up, and adds the hw constraints to sync with the first stream's parameters only when the EP setup for the first stream was confirmed at the open time. However, most of applications handling the full-duplex operations do open both playback and capture streams at first, then set up both streams. This results in skipping the additional hw constraints since the counter-part stream hasn't been set up yet at the open of the second stream, and it eventually leads to "incompatible EP" error in the end. This patch corrects the behavior by always applying the hw constraints for the implicit fb sync. The hw constraint rules are defined so that they check the sync EP dynamically at each invocation, instead. This covers the concurrent stream setups better and lets the hw refine calls resolving to the right configuration. Also this patch corrects a minor error that has existed in the debug print that isn't built as default. Fixes: 5a6c3e11c9c9 ("ALSA: usb-audio: Add hw constraint for implicit fb sync") Signed-off-by: Takashi Iwai <tiwai(a)suse.de> --- This patched was developed primarily as an attemp for the regression of Pioneer devices.

[PATCH v4] ASoC: codecs: wsa881x: add runtime pm support
by Srinivas Kandagatla 21 Apr '22

21 Apr '22

WSA SoundWire Controller does not support Clock stop and performs a soft reset on suspend resume path. Its recommended that WSA881x codecs connected to this are also reset using a hard reset during suspend resume. So this codec driver performs a hard reset during suspend resume cycle.

[PATCH v3 0/3] soundwire: qcom: add pm runtime support
by Srinivas Kandagatla 20 Apr '22

20 Apr '22

This patchset adds pm runtime support to Qualcomm SounWire Controller using SoundWire Clock Stop and Wake up using Headset events on supported instances and instances like WSA which do not support clock stop a soft reset of controller along with full rest of slaves is done to resume from a low power state. Tested it on SM8250 MTP and Dragon Board DB845c Changes since v2: - update log as suggested by Pierre - removing handling clk stop for cases where the controller is soft reset. - add more error checks when calling sdw_bus_prep_clk_stop - update dt-bindings with wakeup-source and interrupt-names properties. --srini Srinivas Kandagatla (3): soundwire: qcom: add runtime pm support dt-bindings: soundwire: qcom: document optional wake irq soundwire: qcom: add in-band wake up interrupt support .../bindings/soundwire/qcom,sdw.txt | 14 +- drivers/soundwire/qcom.c | 206 +++++++++++++++++- 2 files changed, 218 insertions(+), 2 deletions(-) -- 2.21.0

[alsa-devel] [PATCH 00/46] ARM: pxa: towards multiplatform support
by Arnd Bergmann 19 Apr '22

19 Apr '22

Hi PXA maintainers, I'm in the process of getting the old ARM platforms to all build in a single kernel. The largest part of that work is changing all the device drivers to no longer require mach/*.h header files. This series does it for arch/pxa/. As with the omap1 and s3c24xx series I sent before, I don't expect this all to be correct in the first version, though a lot of the patches are fairly simple and I did exhaustive compile-time testing on them. Please test if you have the hardware, or review!

[PATCH v1 0/4] ASoC: ops: Fix stereo change notifications
by Mark Brown 19 Apr '22

19 Apr '22

The event generation coverage I just wrote shows that the generic ASoC ops fail to generate events for stereo controls when only the first channel is changed, we just return the status for the second channel and discard that for the first.

[PATCH] slimbus: qcom: Fix IRQ check in qcom_slim_probe
by Miaoqian Lin 12 Apr '22

12 Apr '22

platform_get_irq() returns negative error number instead 0 on failure. And the doc of platform_get_irq() provides a usage example: int irq = platform_get_irq(pdev, 0); if (irq < 0) return irq; Fix the check of return value to catch errors correctly.
