I’m trying to get PWM working in qcom 6.4 kernel using MPP4. Enabling pm8916_pwm
in the device tree gives me a pwm device in /sys/class/pwm
but after exporting pwm0
when i try to enable it (echo 1 > enable
) i get the following error: write error: Invalid argument
. ive seen other posts that set dcom,dtest
on pm8916_pwm
and ls_exp_gpio_f
but doing so gave the same error. Any additional ideas would be helpful.
