From 522c35e08b53f157ad3e51848caa861b258001e4 Mon Sep 17 00:00:00 2001 From: Stefan Wahren Date: Tue, 5 Dec 2023 21:05:31 +0100 Subject: ARM: dts: bcm2711: Add BCM2711 xHCI support The BCM2711 SoC also has a mostly generic xHCI. The USB port is currently only usable on the Compute Module 4 (e.g. via IO board). Because DWC2 and xHCI share the same PHY, we let the bootloader enable it on demand.
