OF_getprop weirdness - raspberry pi

Hi,
I’m running current as of last week on a raspberry pi B.

i don’t know if this only related to arm, but this is what I have in my rpi-b.dts:
	….
		spi0 {
		     rfid0 {
		     	   compatible = "rfid,mfrc5";
			   spi-chipselect = <0>;
			   reset {
			   	 compatible = "pcd-reset";
				 gpios = <&gpio 6 2>;
			   };
			   lock {
			   	compatible = "lock-1";
				gpios = <&gpio 13 2>;
			   };
			   sense {
			   	 compatible = "sense-1";
				 gpios = <&gpio 19 1>;
			   }; 
		     };
…
and a call to
	uint32_t data[3];
	
	OF_getprop(node, “gpios”, data, sizeof(data)); // node is ‘pcd-reset'
	returns:
		data[0]: 0x03000000
		data[1]: 0x06000000
		data[2]: 0x02000000

which looks to me that it’s in the wrong endian?

cheers,
	danny
