For my case, disabled clock outputs in bootloader are correct. I'm working on
module board with lot of purposes. For one I need to tune frequncy, for other
not. In some cases I can use clk_prepare_enable. For now, I need to tune clk,
so I can't use clk_prepare_enable. Si5351 chip has no problem with enabling
clock output multiple times, when calling clk_set_rate. So if this feature
will not be in driver, I need to stay with patch upon driver.

Many thaks for writting driver,
