Yes, I noticed that.  But it seems to me that the oscillator is enabled
by default anyway, so for now, I treat it as a fixed-rate clock without
gating and have the frequency defined in device tree.

For later, we will probably have another basic clk type supported in
clk framework, fixed-rate clock with a gpio control as the gating.
