[alsa-devel] [PATCH -next 0/3] mop500_ab8500 fixes
by Fabio Baltieri 03 May '13

03 May '13

Hi, these are small fixes to the mop500_ab8500 asoc driver, developed on top of today's ASoC-next. The first patch is actually non ab8500 specific, but as ab8500 seems to be the only codec to use the SND_SOC_DAPM_CLOCK_SUPPLY widget I'm posting it here anyway. The other two patches sort out a mixup of card and codec controls in mop500_ab8500. Thanks, Fabio Fabio Baltieri (3): ASoC: dapm: use clk_prepare_enable and clk_disable_unprepare ASoC: ux500: move clock controls to ab8500-codec ASoC: ux500: register controls to card instead of codec sound/soc/codecs/ab8500-codec.c | 10 ++++++++++ sound/soc/soc-dapm.c | 4 ++-- sound/soc/ux500/mop500_ab8500.c | 20 +++++--------------- 3 files changed, 17 insertions(+), 17 deletions(-) -- 1.8.2

[alsa-devel] [PATCH] ASoC: Added the condition for the channels_min of cpu_dai
by JongHo Kim 02 May '13

02 May '13

Only playback device, the pcm substream for capture does not need to be generated. If codec dai driver has both playback.channels_min and capture.channels_min, and cpu dai driver has only playback.channels_min, soc_new_pcm() will make the pcm substream for capture although DataIN is not connected. So added the condition for the channels_min of cpu_dai in soc_new_pcm().

[alsa-devel] [PATCH] MAINTAINERS: Add linux-samsung-soc list to all related entries
by Tomasz Figa 01 May '13

01 May '13

Several entries in MAINTAINERS file related to Samsung SoCs do not point to linux-samsung-soc mailing list, which is supposed to collect all Samsung SoC-related threads, to ease following of Samsung SoC-related work. This leads to a problem with people skipping this mailing list in their posts, even though they are related to Samsung SoCs. This patch adds pointers to linux-samsung-soc mailing list to affected entries of MAINTAINERS file.

If a 24-bit sample with the value 0x123456 is stored in memory, it looks like this: SNDRV_PCM_FORMAT_S24_LE: 56 34 12 00 SNDRV_PCM_FORMAT_S32_LE: 00 56 34 12 Regards, Clemens

[alsa-devel] [PATCH, for-next] ALSA: usb-audio: caiaq: fix endianness bug in snd_usb_caiaq_maschine_dispatch
by Eldad Zack 30 Apr '13

30 Apr '13

Current code does this: be16_to_cpu(buf[i * 2] << 8 | buf[(i * 2) + 1]) Which is effectively (neglecting the index): be16_to_cpu(be16_to_cpu(*((u16 *) buf))) This means the int16 in the buffer is not converted at all. Daniel Mack confirmed that the driver works on little endian CPUs, leading to the conclusion that the device-side structure is actually little endian. This changes the code to use le16_to_cpu().
