From: Jyri Sarha <jsarha at ti.com>

The first version of patches can been found here:

Changes for v2
 - Dropped our "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

This set of patches fixes the basic audio support for am335x-evm. It
should also be relatively simple to add the necessary nodes to
relevant dts files to get BeagleBone + AudioCape and am335x-evmsk
working too.

The patch set depends on following patches:

[PATCH v11 4/8] ARM: dts: add AM33XX EDMA support 

[PATCH v11 5/8] ARM: dts: add AM33XX SPI DMA support

[PATCH v2] ARM: EDMA: Fix clearing of unused list for DT DMA resources

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

Some commit comments refer to a dmaengine based davinci audio
implementation which is planned for but nothing has been done yet.

Best regards,
