I am having major issues configuring my lcd backlight PWM for the correct configuration. I am using an NXP iMX6 Quad. I have verified that the device tree is correctly configured but I can not even get the PWM to output from the user space control in the terminal window.

Has anyone had a similar issues to this or be able to provide any help?
