+ - samsung,i2s-epll-clock-frequency : epll clock output frequency in Hz
+ - samsung,i2s-sampling-rate : sampling rate, default is 48000
+ - samsung,i2s-bits-per-sample : sample width, defalut is 16 bit
+ - samsung,i2s-channels : nummber of channels, default is 2

+	samsung,i2s-channels = <2>;
+	samsung,i2s-lr-clk-framesize = <256>;
+	samsung,i2s-bit-clk-framesize = <32>;
