Subject: Applied "dt-bindings: ASoC: xlnx, i2s: Document i2s bindings" to the asoc tree

The patch

   dt-bindings: ASoC: xlnx, i2s: Document i2s bindings

has been applied to the asoc tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git 

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.  

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark

+Device-Tree bindings for Xilinx I2S PL block
+
+The IP supports I2S based playback/capture audio
+
+Required property:
+ - compatible: "xlnx,i2s-transmitter-1.0" for playback and
+	       "xlnx,i2s-receiver-1.0" for capture
+
+Required property common to both I2S playback and capture:
+ - reg: Base address and size of the IP core instance.
+ - xlnx,dwidth: sample data width. Can be any of 16, 24.
+ - xlnx,num-channels: Number of I2S streams. Can be any of 1, 2, 3, 4.
+		      supported channels = 2 * xlnx,num-channels
+
+Example:
+
+	i2s_receiver@...80000 {
+		compatible = "xlnx,i2s-receiver-1.0";
+		reg = <0x0 0xa0080000 0x0 0x10000>;
+		xlnx,dwidth = <0x18>;
+		xlnx,num-channels = <1>;
+	};
+	i2s_transmitter@...90000 {
+		compatible = "xlnx,i2s-transmitter-1.0";
+		reg = <0x0 0xa0090000 0x0 0x10000>;
+		xlnx,dwidth = <0x18>;
+		xlnx,num-channels = <1>;
+	};
