What Thunderbolt 4 Chip-set does the Mac mini M2 Pro use to provide four (4) Thunderbolt 4 ports?

What TB4 Chip-set does the Mac mini M2 Pro use to provide four (4) TB4 ports?

It is my understanding that the JHL8540 (Maple Ridge) TB4 "Host" Controller only provides two (2) TB4 ports.

It is also my understanding that the JHL8440 (Goshen Ridge) TB4 "Device / Peripheral" Controller provides four (4) TB4 ports.

So how does the Mac mini M2 Pro provide four (4) TB4 ports?

Is the Mac mini M2 Pro using the JHL8440 (Goshen Ridge) TB4 "Device / Peripheral" Controller, as the "Host" to provide the four (4) TB4 ports?

On the M2 Macs, Apple has eliminated all remnants of Intel chips by having a custom Thunderbolt4/USB4 controller.

( No more Intel chips )

This has been verified by multiple teardowns of M2 series Macs and has found no Intel chips inside.

Even the M1 Macs only had a line driver/retimer chip that was made by Intel for the Thunderbolt ports. so, even they had custom Thunderbolt3/4 and USB4 controllers.

Apple does not disclose this information and speculation on such is forbidden here. Best to take your questions elsewhere.
