IMHO AR9132 SoC can't work without external oscilator.

Can we just move basic extosc declaration to SoC dt file (ar9132.dtsi)?
So board dt file ar9132_tl_wr1043nd_v1.dts will contain only oscilator
clock frequency value.

E.g.

ar9132.dtsi:
============

extosc: oscillator {
compatible = "fixed-clock";
#clock-cells = <0>;
clock-frequency = <40000000>;
};
...
ahb {
apb {

...

pll-controller@18050000 {
...
clocks = <&extosc>;
...



ar9132_tl_wr1043nd_v1.dts:
==========================

...
&extosc {
clock-frequency = <40000000>;
};
