[alsa-devel] [PATCH v2] ASoC: Intel: Skylake: Disable clock and power gating during FW/LIB download
by Guneshwor Singh 13 Mar '18

13 Mar '18

From: Sanyog Kale <sanyog.r.kale(a)intel.com> In order to achieve better DMA performance and reduce download time for firmware and library, it is recommended to disable dynamic clock and power gating. In some scenarios, DMA may wait to accumulate more data and last chunk of data never gets completed if dynamic clock and power gating is kept enabled. This patch adds support to disable/enable dynamic clock and power gating and use it during firmware and library download.

[alsa-devel] [PATCH v2 0/6] ASoC: sun4i-i2s: Updates to the driver
by codekipper＠gmail.com 13 Mar '18

13 Mar '18

From: Marcus Cooper <codekipper(a)gmail.com> Hi All, here is a patch series to add some improvements to the sun4i-i2s driver found whilst getting slave clocking and hdmi audio working on the newer SoCs. The original attempt had some changes related to the slave work but I've left them out for this release as I would still like to do some more investigations. The functionality included with the new patch set has been extended to cover more sample resolutions, multi-lane data output for HDMI audio and loopback so block testing can be made without an external codec. I've also moved away from using tdm to set the slot width and now use a dedicated property. This has been tested on a Pine64 using the ES9023 audio POT board (https://github.com/codekipper/linux-sunxi/commits/upstream) and HDMI audio (https://github.com/codekipper/linux-sunxi/commits/sunxi-wip-a64) BR, CK --- v2 changes compared to v1 are: - removed slave mode changes which didn't set mclk and bclk div. - removed use of tdm and now use a dedicated property. - fix commit message to better explain reason for sign extending - add divider calculations for newer SoCs. - add support for multi-lane i2s data output. - add support for 20, 24 and 32 bit samples. - add loopback property so blocks can be tested without a codec. --- Marcus Cooper (6): ASoC: sun4i-i2s: Add slot width override ASoC: sun4i-i2s: Add regmap field to sign extend sample ASoC: sun4i-i2s: Correct divider calculations ASoC: sun4i-i2s: Add multi-lane functionality ASoc: sun4i-i2s: Add 20, 24 and 32 bit support ASoC: sun4i-i2s: Add support for loopback .../devicetree/bindings/sound/sun4i-i2s.txt | 11 ++ sound/soc/sunxi/sun4i-i2s.c | 199 ++++++++++++++++----- 2 files changed, 170 insertions(+), 40 deletions(-) -- 2.16.2

[alsa-devel] [PATCH] ALSA: pcm: Remove VLA usage
by Takashi Iwai 13 Mar '18

A helper function used by snd_pcm_hw_refine() still keeps using VLA for timestamps of hw constraint rules that are non-fixed size. Let's replace the VLA with a simple kmalloc() array.

[alsa-devel] [PATCH v3 00/22] ASoC: rt5651: jack-detect fixes and improvements
by Hans de Goede 13 Mar '18

13 Mar '18

Hi All, Here is v3 of my rt5651 codec and Intel machine-driver series which mainly consists of various jack-detect related fixes and improvements. Changes in v3: -Drop patches of which the v2 version has been merged (Thanks Mark) -Split out dt-bindings documentation into a separate patch -Rework how we deal with the machine-driver adding properties, so that there no longer is a need for calling the ugly private rt5651_apply_properties function from the machine-driver -Split the patch for moving the configuration of the jack-detect source to device-properties into separate codec and machine-driver patches -Split the patch making the OVCD threshold-current and scale-factor configurable into 2 separate patches Changes in v2; -Get rid of platform_data and use device-properties instead -Split up a couple of the micbias / OVCD / jack-detect patches into smaller patches, as they were doing too much in a single patch -Improved commit messages -Concentrate the knowledge that SSP0 is 16 bits on BYTCR in the fixup function and extract the sample-format from the hw_params in other places Regards, Hans
