The patch
ASoC: img: Add binding document for I2S output controller
has been applied to the asoc tree at
git://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

+Imagination Technologies I2S Output Controller
+
+Required Properties:
+
+ - compatible : Compatible list, must contain "img,i2s-out"
+
+ - #sound-dai-cells : Must be equal to 0
+
+ - reg : Offset and length of the register set for the device
+
+ - clocks : Contains an entry for each entry in clock-names
+
+ - clock-names : Must include the following entries:
+ "sys" The system clock
+ "ref" The reference clock
+
+ - dmas: Contains an entry for each entry in dma-names.
+
+ - dma-names: Must include the following entry:
+ "tx" Single DMA channel used by all active I2S channels
+
+ - img,i2s-channels : Number of I2S channels instantiated in the I2S out block
+
+ - resets: Contains a phandle to the I2S out reset signal
+
+ - reset-names: Contains the reset signal name "rst"
+
+Optional Properties:
+
+ - interrupts : Contains the I2S out interrupts. Depending on
+ the configuration, there may be no interrupts, one interrupt,
+ or an interrupt per I2S channel. For the case where there is
+ one interrupt per channel, the interrupts should be listed
+ in ascending channel order
+
+Example:
+
+i2s_out: i2s-out at 18100A00 {
+ compatible = "img,i2s-out";
+ reg = <0x18100A00 0x200>;
+ interrupts = <GIC_SHARED 13 IRQ_TYPE_LEVEL_HIGH>;
+ dmas = <&mdc 23 0xffffffff 0>;
+ dma-names = "tx";
+ clocks = <&cr_periph SYS_CLK_I2S_OUT>,
+ <&clk_core CLK_I2S>;
+ clock-names = "sys", "ref";
+ img,i2s-channels = <6>;
+ resets = <&pistachio_reset PISTACHIO_RESET_I2S_OUT>;
+ reset-names = "rst";
+ #sound-dai-cells = <0>;
+};
