pwm2 node(dts)

I tried this method and it didn't work, But /sys/class/pwm is empty.

please check and let me know the modification need to do for getting pwm2.

My modification is as follows:

imx8qxp.dtsi:

+ pwm2: pwm@5d020000 {

+ compatible = "fsl,imx8qxp-pwm", "fsl,imx27-pwm";

+ reg = <0x0 0x5d020000 0 0x10000>;

+ clock-names = "ipg", "per";

+ clocks = <&pwm2_lpcg 4>,

+ <&pwm2_lpcg 1>;

+ assigned-clocks = <&clk IMX_SC_R_PWM_2 IMX_SC_PM_CLK_PER>;

+ assigned-clock-rates = <24000000>;

+ power-domains = <&pd IMX_SC_R_PWM_2>;

+ #pwm-cells = <2>;

+ status = "disabled";

+ };

Add the following content to the DTS file of our board

inside &iomuxc {

pinctrl_pwm2_d: pwm2d {

fsl,pins = <IMX8QXP_UART1_RTS_B_LSIO_PWM2_OUT 0x60>;

};

}

&pwm2 {

pinctrl-names = "default";

pinctrl-0 = <&pinctrl_pwm2_d>;

#pwm-cells = <2>;

status = "okay";

};
