1 STMicroelectronics sti ASoC cards
3 The sti ASoC Sound Card can be used, for all sti SoCs using internal sti-sas
4 codec or external codecs.
6 sti sound drivers allows to expose sti SoC audio interface through the
7 generic ASoC simple card. For details about sound card declaration please refer to
8 Documentation/devicetree/bindings/sound/simple-card.txt.
10 1) sti-uniperiph-dai: audio dai device.
11 ---------------------------------------
14 - compatible: "st,stih407-uni-player-hdmi", "st,stih407-uni-player-pcm-out",
15 "st,stih407-uni-player-dac", "st,stih407-uni-player-spdif",
16 "st,stih407-uni-reader-pcm_in", "st,stih407-uni-reader-hdmi",
18 - st,syscfg: phandle to boot-device system configuration registers
20 - clock-names: name of the clocks listed in clocks property in the same order
22 - reg: CPU DAI IP Base address and size entries, listed in same
23 order than the CPU_DAI properties.
25 - reg-names: names of the mapped memory regions listed in regs property in
28 - interrupts: CPU_DAI interrupt line, listed in the same order than the
31 - dma: CPU_DAI DMA controller phandle and DMA request line, listed in the same
32 order than the CPU_DAI properties.
34 - dma-names: identifier string for each DMA request line in the dmas property.
35 "tx" for "st,sti-uni-player" compatibility
36 "rx" for "st,sti-uni-reader" compatibility
38 Required properties ("st,sti-uni-player" compatibility only):
39 - clocks: CPU_DAI IP clock source, listed in the same order than the
43 - pinctrl-0: defined for CPU_DAI@1 and CPU_DAI@4 to describe I2S PIOs for
44 external codecs connection.
46 - pinctrl-names: should contain only one value - "default".
48 - st,tdm-mode: to declare to set TDM mode for unireader and uniplayer IPs.
49 Only compartible with IPs in charge of the external I2S/TDM bus.
50 Should be declared depending on associated codec.
