Therefore, update the maximum supported freq in their respective
dts files.

I did not understand this comment? Do you want me to change something in patch?
I had run checkpatch script on the patch before sending and it did not report any waning or error.
Can this patch not be merged in current tree ?

You mail server is using a content-transfer-encoding that makes patch
applying very difficult. Talk to NXP colleague Anson Huang
