Enable DP83TG720 PHY driver as a module to support TI's DP83TG720
1000BASE-T1 Automotive Ethernet PHY. This is required for the
DP83TG720-IND-SPE-EVM daughter card used with AM642 EVM ICSSG0
interface.

Grepping for DP83TG720 or IND-SPE-EVM gives me no results. Are you sure
this is the board supported upstream?

Why do you have dependencies in defconfig?
Best regards,

Yes, this series adds support adds support for the board:

You're right - the prerequisite-patch-id line shouldn't be in the
defconfig patch. The defconfig change itself has no code dependencies;
it simply enables an already-upstream PHY driver as a module. Will fix
this in v2. Thanks.

I still wonder why there is no DTS for this.

I posted DTS patch separately for this:
https://lore.kernel.org/all/20260226115454.1730618-1-m-malladi@ti.com/
Does it make more sense to post them together as a series ?

Of course, you target the same subsystem - soc. Why triggering all these
investigations and questions...
