Hi Laurent,
I'm not exactly struggling with PLL code right now. I've just get a
new prototype which provides an external 48MHz oscillator for the
clock. So, no need to use PLL there and thus the purpose of this
patch.

However, as you said, dynamic configuration of PLL is one of the
pending issues on the driver and I might address it myself in the
future, but it depends on requirements of the project.


Regards.
