Issue in PWM enabling in RZ/Five

Navya

Hello,

We are using VLP3.0.4 in RZ/Five processor.

Trying to test PWM (MTU3) in RZ/Five using below commands. But PWM is not getting enabled. 

cd /sys/class/pwm/pwmchip0/
echo 0 > export
echo 1000000 > pwm0/period
echo 500000 > pwm0/duty_cycle
echo "normal" > pwm0/polarity
echo 1 > pwm0/enable

Below is the error observed:

root@RZFive:/sys/class/pwm/pwmchip0# echo 0 > export
root@RZFive:/sys/class/pwm/pwmchip0# echo 100000 > pwm0/period
-sh: echo: write error: Invalid argument
root@RZFive:/sys/class/pwm/pwmchip0# echo 50000 > pwm0/duty_cycle
-sh: echo: write error: Invalid argument
root@RZFive:/sys/class/pwm/pwmchip0# echo "normal" > pwm0/polarity
-sh: echo: write error: Invalid argument
root@RZFive:/sys/class/pwm/pwmchip0# echo 1 > pwm0/enable
-sh: echo: write error: Invalid argument

kindly share the fix for the same.

Kindly test the same in EVK and share the observation.

Regards.
