Bindings for I2S controller built into xtfpga Xtensa bitstreams. Required properties: - compatible: shall be "cdns,xtfpga-i2s". - reg: memory region (address and length) with device registers. - interrupts: interrupt for the device. - clocks: phandle to the clk used as master clock. I2S bus clock is derived from it. Examples: i2s0: xtfpga-i2s@d080000 { #sound-dai-cells = <0>; compatible = "cdns,xtfpga-i2s"; reg = <0x0d080000 0x40>; interrupts = <2 1>; clocks = <&cdce706 4>; };
