Cannot compile servo-motor sample application for FRDM-MCXN947

[rtborg]

I'm adding frdm_mcxn947_mcxn947_cpu0.overlay file to boards directory of the application, with contents:

/ {
	servo: servo {
		compatible = "pwm-servo";
		pwms = <&flexpwm1_pwm0 0 PWM_MSEC(20) PWM_POLARITY_NORMAL>;
		min-pulse = <PWM_USEC(700)>;
		max-pulse = <PWM_USEC(2500)>;
	};
};

When compiling using west build -b frdm_mcxn947/mcxn947/cpu0 -s zephyr/samples/basic/servo_motor -p I get a devicetree error:

Trying the same for nucleo f303 board works.
What is the reason for parse error: expected number or parenthesized expression?

Currently this sample is not enabled in zephyr for the FRDM-MCXN947. This sample is enabled on these NXP boards mimxrt1062_fmurt6 and rddrone_fmuk66. If you have any other questions or need assistance with enabled features I'd be happy to help.
