For this, in my mind, I think we need add following parameters in DT.
1. sysclk_src_from_fll --> we need do nothing.
No, how would this work? If nothing else the FLL needs configuration.
Only configure it in machine driver. Then no DT operation.
2. sysclk_src_from_mclk
2.1 use_external_xtal --> we need clock_frequency
2.2 !use_external_xtal --> we need retrieve clock and clock_frequency.
No, this is all handled in the clock binding. If there's a fixed rate
clock the device tree should have a fixed rate clock provided.
Does this acceptable? Or any other better suggestion for this?
Just have the device tree describe the hardware and provide a way of
specifying an optional MCLK.
I will implement an RFC patch, please help review it. Thanks.
Best Regards,
Bo Shen
