QDEC - enabling LED output

[Gabriele]

Hello,
I managed to run nRF5340’s QDEC on development kit.
The dts overlay looks like this

&qdec0 {
  status = "okay";
  a-pin = <37>; /* P1.05 */
  b-pin = <47>; /* P1.15 */
  /* enable-pin = <> */
  led-pin = <45>;
  led-pre = <0>;
  steps = <0>; /* Not Used (but property required) */
};

The problem is I do not see the LED gpio (P1.13) switching on and off on the oscilloscope.
Why ?

Sorry, I've figured out the cause of the issue.
I just had to get initialized to non-zero value the "led-pre" field.
