Note that nanostation-m and nanostation-m-xw are different:

nanostation-m uses &pcie node and caldata extraction in 10-ath9k-eeprom (I fixed the latter only recently):

&pcie {
	status = "okay";

	wifi: wifi at 0,0 {
		reg = <0x0000 0 0 0 0>;

nanostation-m-xw uses &wmac:

&wmac {
	status = "okay";

	mtd-cal-data = <&eeprom 0x1000>;

So, I do not think you will learn much from comparing those two devices.

Off-topic: I just learned that both nanostation-m and -m-xw miss the poe-passthrough switch on ath79.
I will compile a patch for that and submit it on GitHub.
