Looks like out of order (although for some reason before it was also
misordered...).

These are really in the chronological order of the introduction of SoCs.
Isn't that okay to have?

Thanks,

You mean order of release on the market of order of adding files here?
The first is ok, the latter would mean there is no order at all.

It's a nit, so I don't expect to change it. It just increases our
chances for conflicts...

I meant order of release to market. Anyways, I'll send a patch to change
the order to alphabetic order.

It's okay to keep it then in such release-market order. Up to you:

[PATCH 2/2] soc: ti: pruss: Enable support for PRUSS-M subsystem on K3 AM62x SoCs

[Kishon Vijay Abraham I]

The K3 AM62x family of SoC has one PRUSS-M instance and it has two
Programmable Real-Time Units (PRU0 and PRU1). This does not support
Industrial Communications Subsystem features like Ethernet.

The existing pruss platform driver has been updated to support this
through a new AM62x specific compatible.
