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.

This would still allow different sample sizes, but not different sample rates.
+Note that either dmas, dma-names or fsl,imx-fiq are required. + 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
