[alsa-devel] [PATCH 00/16] Support U8500/AB8500 ASoC - patch-set 2
by Ola Lilja 13 Mar '12

13 Mar '12

OK, we have done some serious rewriting of the patch-set. And it now consists of several patches, one for each platform-driver and a few more. Generic code is put in specific generic-patches. All code outside the ASoC-driver has been moved to seperate patches and are upstreamed by Linus Walleij. I will reply to the last mail with answers to your comments. PS. These are the full patch-set to be able to build. The following patches has already been upstreamed by Linus Walleij: ARM: ux500: Add DMA-channels for MSP arm: ux500: Add audio-regulators BR, Ola Kristoffer KARLSSON (7): ASoC: core: Add multi reg control struct & macros ASoC: core: Add 8bit multi reg control accessors ASoC: core: Add range of reg control accessors ASoC: core: Add info accessor for mreg control ASoC: core: Add strobe control ASoC: core: Add macros for 8bit hwdep multi reg cntrl ASoC: core: Add macro for hwdep range of regs control Ola Lilja (9): ARM: ux500: Add DMA-channels for MSP arm: ux500: Add audio-regulators arm: ux500: Add support for MSP I2S-devices ARM: ux500: Add placeholder for clk_set_parent ASoC: Ux500: Add MSP I2S-driver ASoC: codecs: Add AB8500 codec-driver ASoC: Ux500: Add platform-driver ASoC: Ux500: Activate the Ux500 ASoC-driver ASoC: Ux500: Add machine-driver arch/arm/mach-ux500/Makefile | 3 +- arch/arm/mach-ux500/board-mop500-msp.c | 194 ++ arch/arm/mach-ux500/board-mop500-regulators.c | 28 + arch/arm/mach-ux500/board-mop500.c | 7 +- arch/arm/mach-ux500/board-mop500.h | 1 + arch/arm/mach-ux500/clock.c | 15 +- arch/arm/mach-ux500/clock.h | 1 + arch/arm/mach-ux500/devices-common.h | 4 +- arch/arm/mach-ux500/devices-db8500.c | 6 + arch/arm/mach-ux500/include/mach/hardware.h | 2 + arch/arm/mach-ux500/include/mach/msp.h | 29 + include/sound/soc.h | 86 + sound/soc/Kconfig | 1 + sound/soc/Makefile | 3 + sound/soc/codecs/Kconfig | 4 + sound/soc/codecs/Makefile | 7 + sound/soc/codecs/ab8500_audio.c | 2508 +++++++++++++++++++++++++ sound/soc/codecs/ab8500_audio.h | 622 ++++++ sound/soc/soc-core.c | 239 +++ sound/soc/ux500/Kconfig | 41 + sound/soc/ux500/Makefile | 30 + sound/soc/ux500/u8500.c | 150 ++ sound/soc/ux500/ux500_ab8500.c | 828 ++++++++ sound/soc/ux500/ux500_ab8500.h | 25 + sound/soc/ux500/ux500_msp.h | 936 +++++++++ sound/soc/ux500/ux500_msp_dai.c | 899 +++++++++ sound/soc/ux500/ux500_msp_dai.h | 74 + sound/soc/ux500/ux500_msp_i2s.c | 815 ++++++++ sound/soc/ux500/ux500_msp_i2s.h | 41 + sound/soc/ux500/ux500_pcm.c | 537 ++++++ sound/soc/ux500/ux500_pcm.h | 52 + 31 files changed, 8179 insertions(+), 9 deletions(-) create mode 100644 arch/arm/mach-ux500/board-mop500-msp.c create mode 100644 arch/arm/mach-ux500/include/mach/msp.h create mode 100644 sound/soc/codecs/ab8500_audio.c create mode 100644 sound/soc/codecs/ab8500_audio.h create mode 100644 sound/soc/ux500/Kconfig create mode 100644 sound/soc/ux500/Makefile create mode 100644 sound/soc/ux500/u8500.c create mode 100644 sound/soc/ux500/ux500_ab8500.c create mode 100644 sound/soc/ux500/ux500_ab8500.h create mode 100644 sound/soc/ux500/ux500_msp.h create mode 100644 sound/soc/ux500/ux500_msp_dai.c create mode 100644 sound/soc/ux500/ux500_msp_dai.h create mode 100644 sound/soc/ux500/ux500_msp_i2s.c create mode 100644 sound/soc/ux500/ux500_msp_i2s.h create mode 100644 sound/soc/ux500/ux500_pcm.c create mode 100644 sound/soc/ux500/ux500_pcm.h -- 1.7.8.3

[alsa-devel] [PATCH 3.4 1/2] ASoC: wm8994: Prevent ABBA deadlock with CODEC and accdet mutexes
by Mark Brown 12 Mar '12

12 Mar '12

Currently we can the accdet mutex from within DAPM when updating the device state which means we take accdet then the CODEC mutex but we also do the locking the other way around when responding to the jackdet IRQ. Move all the jackdet use of the CODEC mutex out of the accdet lock to avoid this. Since all the DAPM interactions depend only on a single threaded IRQ this is still serialised. The locking improvements in 3.5 allow a better solution there.

Hi, please integrate the two attached patches in ALSA. The first one fixes get_volume_array of the Python bindings for mono channels (also reported as bug 5546). The second just updates one of the pyalsa tests (apparently function names changed some time ago).

ABE has certain requirements towards the FIFO configuration in McBSP. Make it posssible to configure the McBSP FIFO threshold from outside of the McBSP driver stack.
