Optional properties:
- codec-handle: Phandle to a 'codec' node that defines an audio
codec connected to this SSI. This node is typically
a child of an I2C or other control node.
+- dmas: Generic dma devicetree binding as described in
+ Documentation/devicetree/bindings/dma/dma.txt.
+- dma-names: Two dmas have to be defined, "tx" and "rx", if fsl,imx-fiq
+ is not defined.
+- fsl,imx-fiq: Bool property. Use imx-pcm-fiq instead of imx-pcm-dma.
+ Only necessary for some boards with incompatible
+ codec. imx-pcm-fiq will manually filter some data from
+ the codec. It is a workaround for a hardware bug.
Child 'codec' node required properties:
- compatible: Compatible list, contains the name of the codec
Update the fsl-ssi bindings. DMA is no required property anymore and uses the generic DMA bindings. imx-fiq is a new alternative to DMA Signed-off-by: Markus Pargmann <mpa@pengutronix.de> --- Notes: Changes in v4: - Add a comment about hardware bugs for imx-pcm-fiq Changes in v3: - In previous versions, I removed fsl,playback-dma and capture-dma. But they are still in use by fsl_dma.c, so I added them again. Documentation/devicetree/bindings/sound/fsl,ssi.txt | 10 ++++++++++ 1 file changed, 10 insertions(+)
