QDEC device tree issue

[StefanoN]

Hello,

I'm trying to run the QDEC example I find in the nRF Connect SDK.

I'm having issues in setting up the device tree:

/dts-v1/;
#include <nordic/nrf52833_qiaa.dtsi>

/ {
model = "Nordic nRF52833 Dongle NRF52833";
compatible = "nordic,nrf52833-dongle-nrf52833";

chosen {
zephyr,console = &uart0;
zephyr,shell-uart = &uart0;
zephyr,uart-mcumgr = &uart0;
zephyr,sram = &sram0;
zephyr,flash = &flash0;
nordic,nrf-qdec = &qdec0;
};

aliases {
qdec0 = &qdec;
};

nrf-qdec@0 {
compatible = "nordic,nrf-qdec";
reg = <0x0 1>;
interrupts = <18 NRF_DEFAULT_IRQ_PRIORITY>;
pinctrl-0 = <&qdec0_default>;
led-pre = <0>;
steps = <24>;
interrupt-parent = <&nvic>;
};
};

&pinctrl {
qdec0_default: qdec0_default{
group1{
psels = <NRF_PSEL(QDEC_A, 0, 30)>,
<NRF_PSEL(QDEC_B, 0, 29)>;
};
};
};

The problem is that qdec0 is not found from the C code, even though it is present as an alias in the device tree file:

What is wrong with my device tree?

Thanks
