Is it correct? Oh, I see, fair enough. I'm sorry, it was my English skill error. Best regards --- Kuninori Morimoto

[alsa-devel] [PATCH] ASoC: audio-graph-card: add hp and mic detect gpios same as simple-card
by Katsuhiro Suzuki 11 Jun '18

11 Jun '18

This patch adds headphone and microphone jack detection gpios as same as simple-card driver. This feature move into simple-card-utils from simple-card to avoid the duplicating code.

[alsa-devel] [PATCH v2 1/3] ASoC: topology: Improve backwards compatibility with v4 topology files
by Guenter Roeck 06 Jun '18

06 Jun '18

From: Guenter Roeck <groeck(a)chromium.org> Commit dc31e741db49 ("ASoC: topology: ABI - Add the types for BE DAI") introduced sound topology files version 5. Initially, this change made the topology code incompatible with v4 topology files. Backwards compatibility with v4 configuration files was subsequently added with commit 288b8da7e992 ("ASoC: topology: Support topology file of ABI v4"). Unfortunately, backwards compatibility was never fully implemented. First, the manifest size in (Skylake) v4 configuration files is set to 0, which causes manifest_new_ver() to bail out with error messages similar to the following. snd_soc_skl 0000:00:1f.3: ASoC: invalid manifest size snd_soc_skl 0000:00:1f.3: tplg component load failed-22 snd_soc_skl 0000:00:1f.3: Failed to init topology! snd_soc_skl 0000:00:1f.3: ASoC: failed to probe component -22 skl_n88l25_m98357a skl_n88l25_m98357a: ASoC: failed to instantiate card -22 skl_n88l25_m98357a: probe of skl_n88l25_m98357a failed with error -22 After this problem is fixed, the following error message is seen instead. snd_soc_skl 0000:00:1f.3: ASoC: old version of manifest snd_soc_skl 0000:00:1f.3: Invalid descriptor token 1093938482 snd_soc_skl 0000:00:1f.3: ASoC: failed to load widget media0_in cpr 0 snd_soc_skl 0000:00:1f.3: tPlg component load failed-22 This message is seen because backwards compatibility for loading widgets was never implemented. The lack of audio support when running the upstream kernel on recent Chromebooks has been reported in various forums, and can be traced back to this problem. Attempts to fix the problem, usually by providing v5 configuration files, were only partially successful. Let's implement backward compatibility properly to solve the problem for good. Signed-off-by: Guenter Roeck <groeck(a)chromium.org> --- Tested on Caroline (Samsung Chromebook Pro) and Chell (HP Chromebook 13 G1) running v4.17-rc6 plus this patch, with original (v4) configuration files. Also tested on several other Chromebooks with this patch on top of chromeos-4.14. v2: - Move on from RFC/RFT to real patch - Move v4 structure definitions into header file - Add support for copying private capabilities - Declare skl_dfw_v4_module_caps as __packed - Drop duplicate assignment of mconfig->pipe->state sound/soc/intel/skylake/skl-topology.c | 169 +++++++++++++++++++ sound/soc/intel/skylake/skl-tplg-interface.h | 74 ++++++++ sound/soc/soc-topology.c | 7 +- 3 files changed, 248 insertions(+), 2 deletions(-) diff --git a/sound/soc/intel/skylake/skl-topology.c b/sound/soc/intel/skylake/skl-topology.c index 3b1dca419883..9e4c2cb88dea 100644 --- a/sound/soc/intel/skylake/skl-topology.c +++ b/sound/soc/intel/skylake/skl-topology.c @@ -19,6 +19,7 @@ #include <linux/slab.h> #include <linux/types.h> #include <linux/firmware.h> +#include <linux/uuid.h> #include <sound/soc.h> #include <sound/soc-topology.h> #include <uapi/sound/snd_sst_tokens.h> @@ -2724,6 +2725,167 @@ static int skl_tplg_get_desc_blocks(struct device *dev, return -EINVAL;

[alsa-devel] [RFC PATCH] ASoC: pcm512x: enable set_sysclk callback
by Pierre-Louis Bossart 06 Jun '18

06 Jun '18

For codec master mode, the current pcm512x code relies on the clock API. Simple boards such as Hifiberry DAC+ PRO rely on 2 local oscillators to generate 44.1 or 48kHz multiples, with the clock selection being handled by the machine driver toggling GPIOS. The RaspberryPi kernel exposes a "hifiberry,dacpro-clk" clock driver which does nothing but tell the codec driver what rate is set by the machine driver [1][2] This patch suggests an alternate fallback solution to let the codec driver know what the sysclk is based on the existing .set_sysclk callback.

[alsa-devel] unnecessary test?
by Julia Lawall 06 Jun '18

06 Jun '18

In the file sound/pci/ctxfi/cthw20k1.c, the function daio_mgr_dao_init contains: set_field(&ctl->spoctl, SPOCTL_OS << (idx*8), ((conf >> 3) & 0x1) ? 2 : 2); /* Raw */ Could the second argument just be 2? It's true that the preceeding call contains conf >> ..., but in a more useful way, so perhaps it could be useful for uniformity? thanks, julia

[alsa-devel] [PATCH 0/6] soundwire: Add multi link support
by Shreyas NC 06 Jun '18

06 Jun '18

Currently, in the SoundWire subsystem, the concept of stream is limited to a Master and one or more Slaves(Codecs). This series aims to add support for multiple Master(s) sharing the same reference clock and synchronized in the hardware. This patch series adds: - Helpers to lock bus instances part of the stream - Boiler plate conversion of code to support a list of Master runtime - Support multi link bank switch to support synchronization between multiple masters - Add Intel platform ops for pre/post bank switch Sanyog Kale (2): Documentation: soundwire: Add documentation for Multi link soundwire: Add support to lock across bus instances Shreyas NC (3): soundwire: Initialize completion for defer messages soundwire: Add support for multilink bank switch soundwire: intel: Add pre/post bank switch ops Vinod Koul (1): soundwire: Handle multiple master instances in a stream Documentation/driver-api/soundwire/stream.rst | 30 +- drivers/soundwire/bus.c | 1 + drivers/soundwire/bus.h | 4 + drivers/soundwire/intel.c | 54 ++++ drivers/soundwire/stream.c | 429 ++++++++++++++++++-------- include/linux/soundwire/sdw.h | 6 +- 6 files changed, 390 insertions(+), 134 deletions(-) -- 2.7.4
