Changes since v3
- Rebased on top of v3.12-rc4
- Drop already applied patches:
- [PATCH v2 01/11] ASoC: davinci-evm: Move sysclk logic away from evm_hw_params
- [PATCH v2 06/11] ASoC: davinci: Add support for AM33xx SoC Audio
- [PATCH v2 07/11] ASoC: tlv320aic3x: Add regulators to DT bindings document
- [PATCH v2 08/11] ASoC: tlv320aic3x: Add codec pins to DT bindings document
- Add: ASoC: davinci: Fix AM33xx SoC Audio support
- Contains the fixes from Peter:
http://mailman.alsa-project.org/pipermail/alsa-devel/2013-September/066448.html
- Contents of this patch were squashed to "[PATCH v3 06/11] ASoC:
davinci: Add support for AM33xx SoC Audio", but since the patch v2 was
already applied the changes are here as a separate patch.
- Add: ASoC: davinci-mcasp: Remove redundant num-serializer DT parameter
- Change: ASoC: davinci-mcasp: Add DMA register locations to DT
to: ASoC: davinci-mcasp: Add location for data port registers to DT
- Use more accurate name for data port register location
- Improve commit message
- Change: ASoC: davinci-mcasp: Interrupts property to optional and add interrupt-names
to: ASoC: davinci-mcasp: Improve DT bindings document
- Remove #address-cells and #size-cells
- Bracket named interrupts tuples
- Add missing "for" to serial-dir description
- Improve tdm-slots description
- Improve op-mode description
- Add pinctrl-names and pinctrl-0 descriptions
- Change: ARM/dts: am335x-evm: Add audio support for am335x-evm.dts
- Use board specific name 'AM335x-EVM' for the soundcard.
- Use the board specific tlv320aic3106 codec. Use this name instead of generic
tlv320aic3x.
- Remove num-serializer property from mcasp node
- Remove blank lines
- Change: ARM/dts: am33xx: Add mcasp0 and mcasp1 device tree entries
- Bracket all named property tuples
- Add: ARM/dts: am335x-evmsk: Audio support
- The other patches in the set not mentioned here are identical to their
earlier version
Changes since v2
[PATCH v2 01/11] ASoC: davinci-evm: Move sysclk logic away from evm_hw_params
- no change
[PATCH v2 02/11] ASoC: davinci-evm: Add device tree binding
- no change
[PATCH v2 03/11] ASoC: davinci-mcasp: Add DMA register locations to DT
- no change
[PATCH v2 04/11] ASoC: davinci-mcasp: Extract DMA channels directly from DT
- no change
[PATCH v2 05/11] ASoC: davinci-mcasp: Remove interrupt property from DT bindin
- restore binding but make it optional and add interrupt-names property
[PATCH v2 06/11] ASoC: davinci: Add support for AM33xx SoC Audio
- SND_DAVINCI_SOC help "Machine driver for ..." -> "Platform driver for ..."
- SND_AM33XX_SOC_EVM depends on SND_DAVINCI_SOC && SOC_AM33XX
- SND_AM33XX_SOC_EVM does not selcet SND_DAVINCI_SOC
[PATCH v2 07/11] ASoC: tlv320aic3x: Add regulators to DT bindings document
- no change
[PATCH v2 08/11] ASoC: tlv320aic3x: Add codec pins to DT bindings document
- no change
[PATCH v2 09/11] ARM/dts: am33xx: Add mcasp0 and mcasp1 device tree entries
- restore interrupt property and add interrupt-names property
[PATCH v2 10/11] ARM/dts: am33xx: mcasp: Add new dma register location to reg-property
- no change
[PATCH v2 11/11] ARM/dts: am335x-evm: Add audio support for am335x-evm.dts
- no change
Changes from RFC to v2
- Dropped out "ASoC: davinci-mcasp: Add pinctrl support" since
driver core is taking care of this now.
- Cleanup am33xx audio build
- Add regulators to tlv320aic3x DT binding document
- Remove dm365-voice-codec-audio DT support as it has never
been tested an probably does not work
- Add output pins and Line In connector to davinci-evm-audio DT binding doc
- Remove asp_chan_q and ram_chan_q properties from mcasp DT node
in DT mode mcasp is hardcoded to event queue 0 (highest priority)
- Add pins to tlv320aic3x DT bindings document. If I misunderstood
Marks comment and this patch is not needed, then just leave it out
Changes based on TI internal discussions
- Move system clock rate logic away from from evm_hw_params soc-op
- Remove unnecesary #if defined(CONFIG_OF) from davinci-evm.c
- Make dma property DT binding document more exact
- Add only "dma" reg location instead of separate "dma-tx" and "dma-rx"
- Primarily look for "mpu" reg property, but fall back to index 0 if not found
- Remove interrupt property from mcasp DT node as it is not used
- Remove #address-cells and #size-cells mcasp properties as they are not needed
The patch set depends on following patches:
[PATCH v11 4/8] ARM: dts: add AM33XX EDMA support
https://lkml.org/lkml/2013/6/18/49
[PATCH v11 5/8] ARM: dts: add AM33XX SPI DMA support
https://lkml.org/lkml/2013/6/18/55
[PATCH v2 01/11] ASoC: davinci-evm: Move sysclk logic away from evm_hw_params
http://mailman.alsa-project.org/pipermail/alsa-devel/2013-September/066381.html
[PATCH v2 06/11] ASoC: davinci: Add support for AM33xx SoC Audio
http://mailman.alsa-project.org/pipermail/alsa-devel/2013-September/066385.html
This set of patches fixes the basic audio support for am335x-evm and
am335x-evmsk. It should be relatively simple to add the necessary
nodes to relevant dts files to get BeagleBone + AudioCape working too.
I have tried my best not to break the existing support for older
davinci boards, but since I do not have those boards I can not be
sure.
Some commit comments refer to a dmaengine based davinci audio
implementation which is planned for but nothing has been done yet.
Best regards,
Jyri
