AM625: PWM: Need ePWM0 (C13) support for LVDS Display.

Hi Expert!

We are dealing with AM625 chipset.

Our custom HW has LVDS interface. we are dealing with epwm0 signal.

We are using epwm0 pin for pwm C13 bolling number.

For DTS we used below changes.

backlight: backlight {
compatible = "pwm-backlight";
pwms = <&epwm0 0 1000000 0>;
status = "okay";

>;
default-brightness-level = <200>;

};
display {
compatible = "sgd,gktw70sdae4se";
backlight = <&backlight>;
status = "okay";

port@0 {
lcd_in0: endpoint {
remote-endpoint = <&oldi_out0>;
};
};
};

For Pinumux used below 

&main_pmx0 {

main_gp_output_pins_default: main_gp_output_pins_default {
pinctrl-single,pins = <
AM62X_IOPAD(0x0194, PIN_OUTPUT, 7) /* (B19) I2C0_EEPROM_WP ->24c08 pin is default pulled low*/
>;
};

main_epwm0_pins_default: main_epwm0-pins-default {
pinctrl-single,pins = <
AM62X_IOPAD(0x01b8, PIN_OUTPUT, 2) /* (C13) SPI0_CS1.EHRPWM0_B */
>;
};

below is binding node

&epwm0 {
pinctrl-names = "default";
pinctrl-0 = <&main_epwm0_pins_default>;
status = "okay";
};

&dss {

pinctrl-names = "default";
pinctrl-0 = <&main_oldi0_pins_default>;
status = "okay";
};
&dss_ports {
#address-cells = <1>;
#size-cells = <0>;

/* VP1: LVDS Output (OLDI TX 0) */
port@0 {
reg = <0>;
oldi_out0: endpoint {
remote-endpoint = <&lcd_in0>;
};
};
};

We are observing there is no pwm on console and it was not working.

For epwm0 anything different we need to give here?

or anything i miss here ?

Adding logs for your reference.
