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
