There are a few issues with the GPU regulator defined for Jetson Nano which are:
- The GPU regulator is a PWM based regulator and not a fixed voltage regulator.
- The output voltages for the GPU regulator are not correct.
- The regulator enable ramp delay is too short for the regulator and needs to be increased. 2ms should be sufficient.
- This is the same regulator used on Jetson TX1 and so make the ramp delay and settling time the same as Jetson TX1.
