I have ccimx6ulsbc development board. I want to access settings for pwm5, such as duration and frequency, etc. But I found that pwm5 settings only related to the clock under /sys/kernel/debug/clk/pwm5.
I cannot export /sys/class/pwm/pwmchip0/export for accessing settings (enable, duty_cycle, period). What so I have to do in order to export pwm5 control?
