[alsa-devel] [PATCH RESEND v11 0/3] Add ES8328 audio codec
by Sean Cross 17 Aug '14

17 Aug '14

This patchset adds support for the Everest Semi ES8328 audio codec, used in the Novena open source laptop. It also adds support for using the es8328 on IMX boards. We write a machine driver rather than using simple-card because the machine driver needs to support regulators for the speaker amps and as well as supporting headphone jacks, in addition to the i.MX audmux routing. Changes since v10: - Minor documentation reformatting - Minor spacing reformatting in sound/soc/fsl/imx-audio-es8328.c Changes since v9: - Minor formatting corrections - Rework DAPM registers in es8328.h. DAPM widgets use offsets, and the v9 patch turned snd_soc_write() calls into widgets without converting from i2c masks to offsets first. - Rename DAC and ADC PLL to DLL, to reflect latest documentation. Changes since v8: - For the mclk ratios, move from an array to a lookup table, and rename the variable to be clearer. - Move all CHIPPOWER accesses into DAPM supplies. - Fix sloppy compile problems introduced in v8. - Shut down clocks and supplies on suspend, and enable them on resume. - Remove double set of ES8328_MASTERMODE_MSC. Changes since v7: - We now fetch the regulators in the device-level probe rather than in the ASoC-level probe. Changes since v6: - Minor clarification of AUDMUX in imx-audio-es8328.txt - Use u32 instead of int in imx-es8328.c for int-mux and ext-mux - Bounds checking on mux-int-port and mux-ext-port in imx-es8328.c - Remove NULL checks before calling of_node_put() Changes since v5: - Removed empty imx_set_frequency function from imx-es8328.c - Move the clock from imx-audio-es8328 to the es8328 codec itself - Add support for 2x (22.5792 MHz) and 1x (11.2896 MHz) source clocks - Restore registers on resume - Document pins for ES8328, including input pins Changes since v4: - Simplify clock handling and use assigned-clock-parents - Move the codec regulator from the machine driver to the codec - Specify all four regulators, and require their presence - Fix audio recording, such that it enables the PGA Changes since v3: - Add OF bindings for everest,es8328 - Add back in patch to add everest as a vendor prefix - Give clocks more generic names - Document required clocks in DT bindings document Changes since v2: - Change deemph to a bool, and update based on sample rate - Replace value enums with regular enums - Break SPI and I2C drivers into their own modules - Rename everest,es8328 to es8328 as the module wasn't getting detected. Because of this, the patch to vendor-prefixes.txt has been dropped. Changes since v1: - Rename HP/Speaker to OUT1/OUT2 - Use DAPM widgets for startup/shutdown - Add regulator support to machine driver Sean Cross (3): devicetree: bindings: Add Everest Semicodunctor ASoC: add es8328 codec driver ASoC: fsl: add imx-es8328 machine driver Documentation/devicetree/bindings/sound/es8328.txt | 38 ++ .../devicetree/bindings/sound/imx-audio-es8328.txt | 60 ++ .../devicetree/bindings/vendor-prefixes.txt | 1 + sound/soc/codecs/Kconfig | 13 + sound/soc/codecs/Makefile | 6 + sound/soc/codecs/es8328-i2c.c | 60 ++ sound/soc/codecs/es8328-spi.c | 49 ++ sound/soc/codecs/es8328.c | 756 +++++++++++++++++++++ sound/soc/codecs/es8328.h | 314 +++++++++ sound/soc/fsl/Kconfig | 14 + sound/soc/fsl/Makefile | 2 + sound/soc/fsl/imx-es8328.c | 232 +++++++ 12 files changed, 1545 insertions(+) create mode 100644 Documentation/devicetree/bindings/sound/es8328.txt create mode 100644 Documentation/devicetree/bindings/sound/imx-audio-es8328.txt create mode 100644 sound/soc/codecs/es8328-i2c.c create mode 100644 sound/soc/codecs/es8328-spi.c create mode 100644 sound/soc/codecs/es8328.c create mode 100644 sound/soc/codecs/es8328.h create mode 100644 sound/soc/fsl/imx-es8328.c -- 2.0.0

[alsa-devel] [PATCH/RFC] ASoC: Drop const from struct snd_soc_dai_link *of_node members
by Sylwester Nawrocki 16 Aug '14

16 Aug '14

Dropping the const qualifiers prevents "passing argument 1 of ‘of_node_put’ discards ‘const’ qualifier from pointer target type" type warnings when compiling the code dropping reference to cpu_of_node, codec_of_node or platform_of_node with with an of_node_put() function call. This lets us to avoid casting to struct device_node * or caching variables internally in drivers just to be able to properly drop a reference to the OF node on clean up paths.

[alsa-devel] [PATCH 1/2 v2] ASoC: Add HA (HEAD acoustics) DSP codec driver template
by Stefan Roese 16 Aug '14

16 Aug '14

This codec driver template represents an I2C controlled multichannel audio codec that has many typical ASoC codec driver features like volume controls, mixer stages, mux selection, output power control, in-codec audio routings, codec bias management and DAI link configuration. This driver is based on an early version provided by Jarkko Nikula.

[alsa-devel] [PATCH v3] ASoC: tda998x: add a codec to the HDMI transmitter
by Jean-Francois Moine 16 Aug '14

16 Aug '14

This patch adds a CODEC function to the NXP TDA998x HDMI transmitter. The CODEC handles both I2S and S/PDIF input and does dynamic input switch in the TDA998x I2C driver on start/stop audio streaming.

[alsa-devel] [PATCH RFC] ASoC: fsl: Add Freescale Generic ASoC Sound Card with ASRC support
by Nicolin Chen 16 Aug '14

16 Aug '14

The Freescale Generic ASoC Sound Card is a general ASoC DAI Link driver that can be used, ideally, for all Freescale CPU DAI drivers and external CODECs. The idea of this generic sound card is a bit like ASoC Simple Card. However, for Freescale SoCs (especially those released in recent years), most of them have ASRC (Documentation/devicetree/bindings/sound/fsl,asrc.txt) inside. And this is a specific feature that might be painstakingly controlled and merged into the Simple Card driver. So having this driver will allow all Freescale SoC users to benefit from the simplification to support a new card and the capability of wide sample rates support through ASRC. The driver is initially designed for sound card using I2S or PCM DAI formats. However, it's also possible to merge those non-I2S/PCM type sound cards, such as S/PDIF audio and HDMI audio, into this card as long as the merge will not break the original function and as long as there is something redundant that can be abstracted along with I2S type sound cards. As an initial version, it only supports three cards that I can test: imx-audio-cs42888, a new card that links ESAI with CS42888 CODEC imx-audio-sgtl5000, just like the old imx-sgtl5000.c driver imx-audio-wm8962, just like the old imx-wm8962.c driver The driver is also compatible with the old Device Tree bindings of WM8962 and SGTL5000. So we may consider to remove those two drivers after this driver is totally enabled. (It needs to be added into defconfig) Signed-off-by: Nicolin Chen <nicoleotsuka(a)gmail.com> --- .../devicetree/bindings/sound/fsl-asoc-card.txt | 82 +++ sound/soc/fsl/Kconfig | 16 + sound/soc/fsl/Makefile | 2 + sound/soc/fsl/fsl-asoc-card.c | 573 +++++++++++++++++++++ 4 files changed, 673 insertions(+) create mode 100644 Documentation/devicetree/bindings/sound/fsl-asoc-card.txt create mode 100644 sound/soc/fsl/fsl-asoc-card.c diff --git a/Documentation/devicetree/bindings/sound/fsl-asoc-card.txt b/Documentation/devicetree/bindings/sound/fsl-asoc-card.txt new file mode 100644 index 0000000..a96774c --- /dev/null +++ b/Documentation/devicetree/bindings/sound/fsl-asoc-card.txt @@ -0,0 +1,82 @@ +Freescale Generic ASoC Sound Card with ASRC support + +The Freescale Generic ASoC Sound Card can be used, ideally, for all Freescale +SoCs connecting with external CODECs. + +The idea of this generic sound card is a bit like ASoC Simple Card.
