This "max 650mHz" limit is from internal ADD and is also mentioned for
imx8mq.
Peng: you made the change in our internal tree, can you confirm this
requirement also applies to 8mq?
Viorel: Is there any impact from 393216000 vs 786432000 on PLL on audio?
As far as I can know this rate goes through various dividers anyway.
