The patch
ASoC: add hi6210-i2s DT bindings
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

+* Hisilicon 6210 i2s controller
+
+Required properties:
+
+- compatible: should be one of the following:
+ - "hisilicon,hi6210-i2s"
+- reg: physical base address of the i2s controller unit and length of
+ memory mapped region.
+- interrupts: should contain the i2s interrupt.
+- clocks: a list of phandle + clock-specifier pairs, one for each entry
+ in clock-names.
+- clock-names: should contain following:
+ - "dacodec"
+ - "i2s-base"
+- dmas: DMA specifiers for tx dma. See the DMA client binding,
+ Documentation/devicetree/bindings/dma/dma.txt
+- dma-names: should be "tx" and "rx"
+- hisilicon,sysctrl-syscon: phandle to sysctrl syscon
+- #sound-dai-cells: Should be set to 1 (for multi-dai)
+
+Example for the hi6210 i2s controller:
+
+i2s0: i2s@f7118000{
+ compatible = "hisilicon,hi6210-i2s";
+ reg = <0x0 0xf7118000 0x0 0x8000>; /* i2s unit */
+ interrupts = <GIC_SPI 123 IRQ_TYPE_LEVEL_HIGH>; /* 155 "DigACodec_intr"-32 */
+ clocks = <&sys_ctrl HI6220_DACODEC_PCLK>,
+ <&sys_ctrl HI6220_BBPPLL0_DIV>;
+ clock-names = "dacodec", "i2s-base";
+ dmas = <&dma0 15 &dma0 14>;
+ dma-names = "rx", "tx";
+ hisilicon,sysctrl-syscon = <&sys_ctrl>;
+ #sound-dai-cells = <1>;
+};
