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.h... - 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.h...
[PATCH v2 06/11] ASoC: davinci: Add support for AM33xx SoC Audio http://mailman.alsa-project.org/pipermail/alsa-devel/2013-September/066385.h...
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
