Questions about i.mx6 solox clock settings

My software version is 3.14.28.
I want to control the PWM5 output waveform with the M4 core.
The output of PWM5 is normal when the A9 core does not boot to Linux. But every time the A9 core boots to linux, PWM5 cannot output the desired waveform.
I found that re-initializing the PWM5 controller through the M4 core allows the PWM5 to output some irregular waveforms.
I feel that Linux re-initialized the clock used by PWM5 at startup, causing PWM5 to not work properly.
Is there any way to make PWM5 continue to work without interruption after Linux starts?
