[alsa-devel] [PATCH v3 0/3] ASoc: TAS6424: Add support for mute, standby, and faster power on
by Jean-Jacques Hiblot 01 May '18

01 May '18

mute and standby pins are available on the codec. If they are connected, they should be managed by the driver, instead of relying on gpio hogs or on the initial state of the GPIOs. This series also includes a patch to improve the start-up time of the channels by disabling built-in DC diagnostics. Those diagnosdtics basically serve to detect : - wires shorted together - wire shorted to ground or vbat - wire disconnected This is not useful for all platforms and the addition to the startup time is quite noticeable (230ms). The diagnostics can be enabled/disabled using a dedicated ALSA control. Changes in v3: - use SOC_SINGLE_STROBE() to register the "auto diagniostics switch" control Changes in v2: - use a ALSA control to enable/disable the auto diagnostics instead of relying on a DTS property. - fixed typos - use gpios (plural) instead of gpio in the documentation of the bindings Jean-Jacques Hiblot (3): ASoC: tas6424: Add support for the standby pin ASoC: tas6424: Add support for the mute pin ASoC: tas6424: Allow disabling auto diagnostics for faster power-on .../devicetree/bindings/sound/ti,tas6424.txt | 2 + sound/soc/codecs/tas6424.c | 72 +++++++++++++++++++++- sound/soc/codecs/tas6424.h | 4 ++ 3 files changed, 75 insertions(+), 3 deletions(-) -- 2.7.4

[alsa-devel] [PATCH v2 0/6] ARM/ASoC: omap: n810 audio support
by Peter Ujfalusi 01 May '18

01 May '18

Hi, Changes since v1: - Fixed up the aic33 dts patch with missing entries needed for capture - Added comment and new widget for the non working HS Mic The verification of the sdma-pcm on OMAP2 got delayed by non working audio on n810. With the following patches audio works on n810 (both with the old omap-pcm and the new sdma-pcm). I believe the DTS and ASoC patches are fine to go via different tree, but I wanted to keep the patches together for easier testing. The series does not have any dependencies, I will rebase the sdma-pcm series on top of this and resend. Playback to Speaker, Headset is working. Capture from DMIC is working. Capture from HS mic is not working due to missing mic bias (from Retu/Vilma).

[alsa-devel] [PATCH v2 00/13] ALSA: dice: use cache of stream formats to generate PCM rules/constraints
by Takashi Sakamoto 01 May '18

01 May '18

Hi, This patchset updates my previous one: [alsa-devel] [PATCH 00/11] ALSA: dice: use cache of stream formats to generate PCM rules/constraints http://mailman.alsa-project.org/pipermail/alsa-devel/2018-April/134983.html Once, ALSA dice driver cached stream formats to generate PCM constraints/rules. The cache is created by changing current sampling transmission frequency step by step directly at unit probing process. This feature was dropped because it changes state of clock on target device thus it's against users' expectation[1]. However this is not necessarily convenient because reconfiguration of sampling rate is not available. TC Applied Technologies (TCAT) has extended protocol for DICE interface, a.k.a EAP (Extended Application Protocol). In this extension, drivers can retrieve information of stream formats without changing state of target unit. Fortunately, this protocol is supported widely by many models. This patchset regain the cache to generate PCM constraints/rules by using this protocol. Userspace applications can reconfigure sampling rate via ALSA PCM interface. For units which doesn't support the extension, available set of sampling rate is still restricted at current sampling transmission frequency. This is also inconvenient and this patchset introduces a solution. Structure for unit entry (struct ieee1394_device_id) has a member for unit-specific data. This patchset uses it for callback function to handle hard-coded stream format. In this time, I adopt this way for some known models produced by TC Electronic and Alesis. If users find their models still have restrictions in a point of available sampling transmission frequency, it's preferable to work for this way. Changes from v1: - rename members for the channel cache. - add minor refactoring. - fix a bug that sampling transmission frequency is not changed via ALSA PCM interface. - fix a bug that current stream formats are reused after changing sampling transmission frequency.

preallocate pages should use platform device, since we set dma mask for platform device.
