Below is a fix for am473x that works for me as tested with
am473x-sk-evm. Care to test please?

I'll send also a similar fix for am335x separately. And
then for dra7. Looks like for dra7 we're also missing the
mcasp optional clocks too.

Regards,

Tony

Subject: [PATCH] ARM: dts: Add missing ranges for am437x mcasp l3 ports

We need to add mcasp l3 port ranges for mcasp to use a correct l3
data port address for dma.
