Subject: [PATCH v4 03/14] ASoC: dt-bindings: convert designware-i2s to dt-schema
From: Conor Dooley <conor.dooley@...rochip.com>
Convert the Synopsys DesignWare I2S controller binding to dt-schema.
There was no listed maintainer but Jose Abreu was the last editor of the
txt binding so add him as maintainer.

-DesignWare I2S controller
-
-Required properties:
- - compatible : Must be "snps,designware-i2s"
- - reg : Must contain the I2S core's registers location and length
- - clocks : Pairs of phandle and specifier referencing the controller's
- clocks. The controller expects one clock: the clock used as the sampling
- rate reference clock sample.
- - clock-names : "i2sclk" for the sample rate reference clock.
- - dmas: Pairs of phandle and specifier for the DMA channels that are used by
- the core. The core expects one or two dma channels: one for transmit and
- one for receive.
- - dma-names : "tx" for the transmit channel, "rx" for the receive channel.
-
-Optional properties:
- - interrupts: The interrupt line number for the I2S controller. Add this
- parameter if the I2S controller that you are using does not support DMA.
-
-For more details on the 'dma', 'dma-names', 'clock' and 'clock-names'
-properties please check:
- * resource-names.txt
- * clock/clock-bindings.txt
- * dma/dma.txt
-
-Example:
-
- soc_i2s: i2s@...90000 {
- compatible = "snps,designware-i2s";
- reg = <0x0 0x7ff90000 0x0 0x1000>;
- clocks = <&scpi_i2sclk 0>;
- clock-names = "i2sclk";
- #sound-dai-cells = <0>;
- dmas = <&dma0 5>;
- dma-names = "tx";
- };
