Subject: [PATCH V3 0/3] ARM: dts: bcm2711: Add BCM2711 xHCI support
Date: Sun, 3 Dec 2023 00:22:14 +0100 [thread overview]
Message-ID: <20231202232217.89652-1-wahrenst@gmx.net> (raw)
In contrast to the Raspberry Pi 4, the Compute Module 4 or the IO board
does not have a VL805 USB 3.0 host controller, which is connected via
PCIe. Instead, the BCM2711 on the Compute Module provides the built-in
xHCI.
Changes in V3:
- introduce a new compatible for BCM2711 in order to make the
power domain dependency SoC specific, which also results in
a driver change
Changes in V2:
- adjust xHCI compatible as suggested by Justin & Florian
- keep xHCI disabled in order to let the bootloader decide which
USB block should be enabled, which result in a drop of patch 3
