arm64: dts: rockchip: add dual-role usb3 hosts to rk3588
From: Heiko Stuebner <heiko.stuebner@...> Date: Tue, 12 Dec 2023 14:27:37 +0100
Commit-Message
Apart from the host-only usb3 controller (host2) the rk3588 also provides two dual-role controllers. On the Tiger-Haikou combination these are connected to the lower usb3-host port in host-only mode and the micro-usb3 port for dual-role operation. Add the necessary controllers, phys to the Tiger-Haikou board and enable the usb-id extcon. Signed-off-by: Heiko Stuebner <heiko.stuebner@...>
