The default setting uses the main CPU clock and I need to change it to use one of the PLL based clocks. I can see where this selector is available as cko1_sel, but it's not clear to me if/where/how I can set this to be pll3_sw in the device tree (which in the modern world is the only place for target platform configuration and control). Any ideas or pointers?
