| * Hisilicon 6210 i2s controller |
| |
| Required properties: |
| |
| - compatible: should be one of the following: |
| - "hisilicon,hi3660-i2s-1.0" |
| - 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 hi3660 i2s controller: |
| |
| i2s2: hisi_i2s { |
| compatible = "hisilicon,hi3660-i2s-1.0"; |
| reg = <0x0 0xe804f800 0x0 0x400>, |
| <0x0 0xe804e000 0x0 0x400>; |
| pinctrl-names = "default"; |
| pinctrl-0 = <&i2s2_pmx_func &i2s2_cfg_func>; |
| dmas = <&asp_dmac 18 &asp_dmac 19>; |
| dma-names = "rx", "tx"; |
| #sound-dai-cells = <0>; |
| }; |
| |
| sound { |
| compatible = "simple-audio-card"; |
| simple-audio-card,name = "hikey-hdmi"; |
| simple-audio-card,format = "i2s"; |
| |
| simple-audio-card,bitclock-master = <&sound_master>; |
| simple-audio-card,frame-master = <&sound_master>; |
| |
| sound_master: simple-audio-card,cpu { |
| sound-dai = <&i2s2>; |
| }; |
| |
| simple-audio-card,codec { |
| sound-dai = <&adv7533>; |
| }; |
| }; |
