[alsa-devel] dummy codec + simple card combination
by Belisko Marek 03 Apr '15

03 Apr '15

Hi, I'm trying to add audio support for gta04 (for gsm + bt and fm audio). All audio sources are clock masters so basically connection is dummy codecs -> cpu dai (mcbsp ports). For implementing such thing I can see 2 options: 1. simple card driver which can easily describe cpu dai interface but dummy codec cannot because there are no DT bindings (there was sever attempts to add DT bindings for dummy-codec but AFAIK none was accepted) This turns it to only solution to create gta04 soundcard which will get from DT cpu dai links and use in card driver dummy codecs directly. Is my assumption correct? I would like to get some feedback before wasting my time with implementing something which cannot be pushed mainline. Thanks for all suggestions.

[alsa-devel] [RFC 0/11] dw_hdmi cleanups, audio preparation, helpers and ahb audio support
by Russell King - ARM Linux 02 Apr '15

02 Apr '15

I'm sending this series for comments, and to allow people to update their code bases (for those who are using my AHB audio driver on iMX6). This is really several series, and I'm not expecting this to be ready for the upcoming merge window. That said, if anyone wants to say that they're happy with some of the initial four patches, I'm happy to queue those for David, if he's willing to take them. This series applies on top of my previous series, which finished with the patch "drm: bridge/dw_hdmi: adjust n/cts setting order". The first four patches are a few cleanups to the dw_hdmi driver. The next two patches introduce new interfaces to the dw_hdmi driver to support AHB audio, including the errata found on iMX6 which requires N to be programmed to zero when the audio FIFO is not full. I'm expecting some discussion with these last two as we try to work out how to deal with the two variants of audio support for this part (AHB audio vs I2S audio). The following three add various helpers to the DRM and ALSA subsystems for audio support which is non-specific to the AHB audio driver. For DRM, this is a helper macro to obtain the pointer into the short audio descriptors. For ALSA, it's a set of helpers to restrict an audio PCM device's capabilities according to the ELD, and to generate the IEC958 channel status data. If these helpers are acceptable, we can convert a number of drivers to them. The ELD helper isn't quite finished, but should be sufficient for initial testing. The last two patches add support for the dw_hdmi audio. This is an ALSA driver rather than an ASoC driver as it's a pretty simple affair. I couldn't find a suitable location in the sound/ subtree to place it, so I've placed it next to the bridge - yes, we probably need to find it a better home in the sound/ subtree, but it currently makes use of dw_hdmi.h in the directory it lives. drivers/gpu/drm/bridge/Kconfig | 11 + drivers/gpu/drm/bridge/Makefile | 1 + drivers/gpu/drm/bridge/dw_hdmi-ahb-audio.c | 566 +++++++++++++++++++++++++++++ drivers/gpu/drm/bridge/dw_hdmi-ahb-audio.h | 14 + drivers/gpu/drm/bridge/dw_hdmi.c | 250 ++++++++----- drivers/gpu/drm/bridge/dw_hdmi.h | 3 + include/drm/bridge/dw_hdmi.h | 7 + include/drm/drm_edid.h | 19 + include/sound/pcm_drm_eld.h | 6 + include/sound/pcm_iec958.h | 9 + sound/core/Kconfig | 6 + sound/core/Makefile | 3 + sound/core/pcm_drm_eld.c | 91 +++++ sound/core/pcm_iec958.c | 70 ++++ 14 files changed, 964 insertions(+), 92 deletions(-) -- FTTC broadband for 0.8mile line: currently at 10.5Mbps down 400kbps up according to speedtest.net.

[alsa-devel] [PATCH] ASoC: atmel-pcm-dma: increase buffer_bytes_max
by Alexandre Belloni 02 Apr '15

02 Apr '15

atmel-pcm-dma is not limited to a buffer size of 64kB like atmel-pcm-pdc. Increase buffer_bytes_max to 512kB to allow for higher bit rates (i.e. 32bps at 192kHz) to work correctly. By default, keep the prealloc at 64kB.

[alsa-devel] ASoC: cs4271: init/timing problem
by Pascal Huerst 02 Apr '15

02 Apr '15

Hey all, We have a custom built hw, based on am335x and from time to time we need to rmmod/modprobe the ASoC machine driver. Depending on the hw, the first call to regmap_update_bits(..) in cs4271_codec_probe(..) fails with -EREMOTEIO. The error is originated in: drivers/i2c/busses/i2c-omap.c and happens if no i2c package acknowledge is received by the host. I think this is a timing issue and on some devices, the codec is just not ready yet, for communication. What is the right way to fix that? My attempt would be something like this: const int retries = 5; while (retries) { ret = regmap_update_bits(cs4271->regmap, CS4271_MODE2, CS4271_MODE2_PDN | CS4271_MODE2_CPEN, CS4271_MODE2_PDN | CS4271_MODE2_CPEN); if (ret == -EREMOTEIO) { retries--; udelay(1); continue; } else if (ret) return ret; break; } But I might also just add a proper delay before the first call to regmap_update_bits(..) So what is the proper way to handle this? Thanks Pascal

A driver's device data should and can be const. This is a follow-up on commit 33187fb4a203 (ASoC: rsnd: constify of_device_id array) which marked the of_device_id as const. Signed-off-by: Uwe Kleine-König <u.kleine-koenig(a)pengutronix.de> --- This is also patch 4 of my series[1] which degraded to this hunk when rebasing to next because all the other changes were already addressed by Fabian.

[alsa-devel] [PATCH v2 0/4] ASoC: constification and random cleanups
by Uwe Kleine-König 01 Apr '15

01 Apr '15

Hello, this is the series sent on Sunday rebased on next. There was a conflict with commit c660c0a80586 (ASoC: fsi: constify of_device_id array) which did a part of my 2nd patch but already conflicted with the first one. Mark said he already took patch 3, but that should not be a problem. Patch 4 applied just fine to next, so this is just a resend. Best regards Uwe Uwe Kleine-König (4): ASoC: fsi: reorder code to make a forward declaration superfluous ASoC: fsi: mark several data structures as const ASoC: fsi: fix license specification ASoC: mark of_device_id and device data as constant sound/soc/sh/fsi.c | 71 ++++++++++++++++++++++++------------------------ sound/soc/sh/rcar/core.c | 4 +-- 2 files changed, 37 insertions(+), 38 deletions(-) -- 2.1.4
