Hi ,
I am working on imx8mq board and trying to enable SAI1 mclk.
Device tree configuration:
pin configuration
pinctrl_sai1: sai1grp {
fsl,pins = <
MX8MQ_IOMUXC_SAI1_MCLK_SAI1_MCLK 0xd6
MX8MQ_IOMUXC_SAI1_TXC_SAI1_TX_BCLK 0xd6
MX8MQ_IOMUXC_SAI1_TXFS_SAI1_TX_SYNC 0xd6
MX8MQ_IOMUXC_SAI1_RXD0_SAI1_RX_DATA0 0xd6
MX8MQ_IOMUXC_SAI1_TXD0_SAI1_TX_DATA0 0xd6
>;
};
sound-ssm2518 {
compatible = "simple-audio-card";
status="okay";
simple-audio-card,name = "ssm2518-audio";
simple-audio-card,format = "i2s";
simple-audio-card,bitclock-master = <&dai_cpu>;
simple-audio-card,frame-master = <&dai_cpu>;

sound-dai = <&sai1>;
};

sound-dai = <&ssm2518>;

};

assigned-clocks = <&clk IMX8MQ_CLK_SAI1>,

assigned-clock-rates = <0>, <12288000>;
fsl,sai-mclk-direction-output;
fsl,sai-synchronous-rx;
status = "okay";
};
SO, I configure device tree for mclk but got error.
failed to get mclk1 clock
Please help me on this issue.
Thanks,
