[alsa-devel] [PATCH v3 0/9] Add support for the audio codec on Allwinner V3s
by Icenowy Zheng 06 Jun '17

06 Jun '17

Allwinner V3s features a audio codec with dedicated digital and analog parts, like the ones on A23/H3, but much simpler (lack of MIC2, LINE IN and MBIAS). Add support for it. In order to make the codec usable, DMA support is also added in this series. Patch 1 split out MBIAS in analog codec driver. Patch 2 prepared a set of objects that have MIC2 and LINEIN stripped out for V3s. Patch 3/4 adds support for V3s in analog/digital codec. Patch 5 add the gate bit as a common quirk of sun6i-dma driver, as V3s also needs it. Patch 6 really adds support for V3s in DMA engine. Patch 7/8/9 adds three parts of device tree: DMA engine, codec support and enable the codec for Lichee Pi Zero dock.

[alsa-devel] [PATCH] ASoC: rsnd: Document optional reset properties
by Geert Uytterhoeven 06 Jun '17

Document the optional properties for describing module resets, to support resetting these modules on R-Car Gen2 and Gen3. Note that the audio module has resets for the Serial Sound Interfaces only.

[alsa-devel] [PATCH] ASoC: atmel: tse850: fix off-by-one in the "ANA" enumeration count
by Peter Rosin 06 Jun '17

At some point I added the "Low" entry at the beginning of the array without bumping the enumeration count from 9 to 10. Fix this.

[alsa-devel] [PATCH] ASoC: cs35l35: Add additional delay for reset
by Charles Keepax 06 Jun '17

06 Jun '17

Very fast systems may violate the minimum constraints for time the reset line needs to remain low, or communicate with the device too soon after releasing the reset. Fix this by adding some delays in to allow the chip to properly reset, also factor out the reset into a function as it is likely it will be re-used in later additions to the driver.

[alsa-devel] [RFC PATCH v2] ASoC: Intel: sst: Delete sst_shim_regs64; saved regs are never used
by Douglas Anderson 06 Jun '17

06 Jun '17

In commit 9a075265c6dc ("ASoC: Intel: sst: Remove unused function sst_restore_shim64()"), we deleted the sst_restore_shim64() since it was never used. ...but a quick look at the code shows that we should also be able to remove the sst_save_shim64() function and the structure members we were storing data in. Once we delete sst_save_shim64() there are no longer any users of the 'sst_shim_regs64' structure. That means we can delete it completely and also avoid allocating memory for it. This saves a whopping 136 bytes of devm allocated memory. We also get the nice benefit of avoiding an error path in the init code. Note that the saving code that we're removing (and the comments talking about how important it is to do the save) has been around since commit 336cfbb05edf ("ASoC: Intel: mrfld- add ACPI module"). Signed-off-by: Douglas Anderson <dianders(a)chromium.org> --- This problem was found only by code inspection and only compile tested. Hence, RFC.

[alsa-devel] [PATCH 0/4] Yet another fixes for ALSA timer info leaks
by Takashi Iwai 06 Jun '17

06 Jun '17

Hi, this is a patchset to paper over a bug in ALSA timer core code about the race between read and ioctl. As a side-effect of the race, it may allow to read some uninitialized kmalloced memory. The first two patches cover the issue, so marked as stable, while the rest two patches are rather cleanups and more hardening. I'm going to queue the first to for-linus for 4.12-rc, and the latter two to for-next, for 4.13. thanks, Takashi === Takashi Iwai (4): ALSA: timer: Fix race between read and ioctl ALSA: timer: Fix missing queue indices reset at SNDRV_TIMER_IOCTL_SELECT ALSA: timer: Improve user queue reallocation ALSA: timer: Wrap with spinlock for queue access sound/core/timer.c | 103 ++++++++++++++++++++++++++--------------------------- 1 file changed, 51 insertions(+), 52 deletions(-) -- 2.13.0
