I got the same errors with the 2nd clock prop;

fsl-sai 308b0000.sai: ASoC: can’t set 308b0000.sai hw params: -22

fsl-sai 308b0000.sai: failed to derive required Rx rate: 705600

I got the same problem with the second clock proposition.

Also can’t get the exact DTS clock rate 24576000 , in clk summary this value is 23266286 .

Either the clocks are being used by another node or the clock sources isn’t right.

PS: Note that with basic definition of codec cpu sai2 and sound in DTS this micro works with frequencies in range 10000 ~ 11500 .
