HI，
I'm porting wm8904 device driver to IMX8MM system，but the dts file always compliled error。
my env as follows：
- CPU ： IMX8MM
- System ：Linux imx8mmevk 5.4.24
DTS As Follows：
&i2c4 {
clock-frequency = <100000>;
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_i2c4>;
status = "okay";
codec01: wm8904@1a {
compatible = "wlf,wm8904";
reg = <0x1a>;
wlf,shared-lrclk;
clocks = <&clks IMX8MM_CLK_SAI5_ROOT>;
clock-names = "mclk0";
};
};
Compile Error as follows：
