@kevinplatt YES! - got it The 0x80 in  simple-audio-card,mclk-fs = < 0x80 >; isnt a phandle to convert - its a VALUE! (when I only could better read .dts-files  ) The error code [ 446.975450] sun4i-i2s 1c22c00.dai: Unsupported oversample rate: 127 [ 446.975465] sun4i-i2s 1c22c00.dai: ASoC: can't set 1c22c00.dai hw params: -22 did it tell me, because hex 0x7f is 127 (unsupportted oversample rate, because it starts to be supported at 128) and hex 0x80 is 128
