[alsa-devel] [PATCH 0/3] ALSA: hda - enable display audio for Intel Broadwell
by mengdong.lin＠intel.com 09 Jan '14

09 Jan '14

From: Mengdong Lin <mengdong.lin(a)intel.com> The following patches enable HDMI/DP audio for Intel Broadwell platform from audio driver side. Gfx driver just reuses Haswell audio enabling code. Mengdong Lin (3): ALSA: hda - add device ID for Broadwell display audio controller ALSA: hda - add codec ID for Broadwell display audio codec ALSA: hda/hdmi - apply all Haswell fix-ups to Broadwell display codec sound/pci/hda/hda_intel.c | 3 +++ sound/pci/hda/patch_hdmi.c | 17 +++++++++++------ 2 files changed, 14 insertions(+), 6 deletions(-) -- 1.8.1.2

[alsa-devel] [PATCH] ASoC: da9055: Partially fix device registration
by Mark Brown 08 Jan '14

08 Jan '14

From: Mark Brown <broonie(a)linaro.org> It has never been possible to even load the da9055 driver since both the MFD and CODEC drivers register the I2C device "da9055". Fix this by using the usual pattern for MFDs with multiple I2C addresses and having the CODEC driver reference an I2C dummy registered by the MFD. Since I don't know which I2C address to use for the CODEC a FIXME has been left in the MFD, this doesn't make anything any worse since the device has never been able to load in the first place.

[alsa-devel] [PATCH 00/11] ASoC/MFD: twl4030 codec local register cache removal
by Peter Ujfalusi 08 Jan '14

08 Jan '14

Hi, After the twl6040 codec, now it is time for the twl4030 codec driver to loose it's local reg cache and let the MFD core's regmap to take care of the caching. We have different functions behind of the 0x49 i2c address in twl (where the audio registers can be found between 0x01 - 0x49). I mark all non audio registers as volatile for now to avoid any side effect of the caching. Gradually other functionalities can also move their caching to regmap to simplify the code. I have included couple of clean up patches after the local regcache removal to the series to freshen up the code a bit. Regards, Peter --- Peter Ujfalusi (11): MFD: twl-core: Simplify IO wrapper functions by moving common code out MFD: twl-core: API to set the regcache bypass for a given regmap in twl MFD: twl-core: Enable regcache for audio registers ASoC: twl4030: Separate write condition checking from I/O function ASoC: twl4030: Remove check defaults functionality ASoC: twl4030: Remove reset registers functionality ASoC: twl4030: Introduce local ctl register cache ASoC: twl4030: Remove local reg cache ASoC: twl4030: Parameter alignment fixes (for code consistency) ASoC: twl4030: Move the ctl cache update local to twl4030_write() function ASoC: twl4030: Pass the twl4030_priv directly to twl4030_can_write_to_chip() drivers/mfd/twl-core.c | 190 +++++++++++++++++++---- include/linux/i2c/twl.h | 5 +- sound/soc/codecs/twl4030.c | 376 ++++++++++++++++----------------------------- 3 files changed, 300 insertions(+), 271 deletions(-) -- 1.8.5.2

[alsa-devel] [PATCH v3 0/5] ASoC: add CSR SiRFSoC sound drivers
by RongJun Ying 08 Jan '14

08 Jan '14

From: Rongjun Ying <rongjun.ying(a)csr.com> This patchset adds CSR SiRFSoC sound drivers including: 1. the platform DMA driver which will be shard by all DAI 2. the I2S CPU DAI driver 3. the USP-based PCM CPU DAI driver 4. CPU DAI and Codec driver for internal chip codec 5. the mach driver for EVB board using internal codec -v3: 1. Use devm_* API for driver 2. Remove the extcon stuff code 3. Calculated automatically the div vaule at runtime based on the sample rate 4. Automatically discovering the configuration of pcm hardware from the dmaengine driver 5. Add binding documents Rongjun Ying (5): ASoC: sirf: add sirf platform driver which provides DMA ASoC: sirf: add I2S CPU DAI driver ASoC: usp-pcm: add CPU DAI driver for PCM simulated from USP ASoC: sirf-soc-inner: add drivers for both CPU and Codec DAIs ASoC: sirf-inner: add mach driver for SiRFSoC internal codec .../bindings/sound/sirf,inner-audio-codec.txt | 41 ++ sound/soc/Kconfig | 1 + sound/soc/Makefile | 1 + sound/soc/sirf/Kconfig | 18 + sound/soc/sirf/Makefile | 11 + sound/soc/sirf/sirf-audio.h | 268 ++++++++ sound/soc/sirf/sirf-i2s.c | 435 +++++++++++++ sound/soc/sirf/sirf-inner.c | 155 +++++ sound/soc/sirf/sirf-pcm.c | 68 ++ sound/soc/sirf/sirf-soc-inner.c | 653 ++++++++++++++++++++ sound/soc/sirf/sirf-usp.c | 463 ++++++++++++++ sound/soc/sirf/sirf-usp.h | 276 +++++++++ 12 files changed, 2390 insertions(+), 0 deletions(-) create mode 100644 Documentation/devicetree/bindings/sound/sirf,inner-audio-codec.txt create mode 100644 sound/soc/sirf/Kconfig create mode 100644 sound/soc/sirf/Makefile create mode 100644 sound/soc/sirf/sirf-audio.h create mode 100644 sound/soc/sirf/sirf-i2s.c create mode 100644 sound/soc/sirf/sirf-inner.c create mode 100644 sound/soc/sirf/sirf-pcm.c create mode 100644 sound/soc/sirf/sirf-soc-inner.c create mode 100644 sound/soc/sirf/sirf-usp.c create mode 100644 sound/soc/sirf/sirf-usp.h -- 1.7.5.4
