"Unsupported Clock setting 441000 for DAI 0" for rt5640 audio driver

[Yocto_learner]

Hello Everyone, 

I am working with two rt5640 audio chips having imx8mplus soc. In both of the audio chip one is working in slave mode and the other one is master. IMX8MPLUS soc is master mode for rt5640 slave and slave for rt5640 master. I am not getting sound in any one of them.

But first I need to focus for the rt5640 slave chip and have to work it. I am able to make audio card for rt5640 and also getting data on the i2c-3 bus for it. But when I try to play a wav file or record I get "Unsupported clock setting 44100 for  DAI 0".

It is not getting the proper clock setting for rt5640 work in slave mode. Here I am attaching some pieces of code which I have configured and rt5640 driver code. 

imx8mp-evk.dts

&i2c4 {

clock-frequency = <400000>;

pinctrl-names = "default";

pinctrl-0 = <&pinctrl_i2c4>;

};

};

};

sound-rt5640 {

staus = "okay";
};

why am I getting this unsupported clock setting how to resolve this for rt5640 slave working? 

rt5640 driver code: rt5640.c 

Thanks in Advance
