Subject: [PATCH V3 3/3] ARM: dts: bcm2711: Add BCM2711 xHCI support
Date: Sun, 3 Dec 2023 00:22:17 +0100 [thread overview]
Message-ID: <20231202232217.89652-4-wahrenst@gmx.net> (raw)
In-Reply-To: <20231202232217.89652-1-wahrenst@gmx.net>
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.
