[PATCH 19/19] arm64: dts: apple: t60xx: Add USB4 ACIO and NHI

Sun Aug 30 13:19:37 PDT 2026
Add the ACIO host router, NHI, DART and mailbox nodes for the four ATC
instances on each t600x and t602x die and connect the host routers to
the Type-C connectors on the MacBook Pro (j314/j316 and j414/j416), Mac
Studio (j375 and j475), Mac mini (j474) and Mac Pro (j180d) boards.
