Subject: [PATCH] arm64: dts: rockchip: add usb typec host support to rk3588-jaguar
From: Heiko Stuebner <heiko.stuebner@...rry.de>
Jaguar has two type-c ports connected to fusb302 controllers that can
work both in host and device mode and can also run in display-port
altmode.
While these ports can work in dual-role data mode, they do not support
powering the device itself as power-sink. This causes issues because
the current infrastructure does not cope well with dual-role data
without dual-role power.
So add the necessary nodes for the type-c controllers as well
as enable the relevant core usb nodes, but limit the mode to host-mode
for now until we figure out device mode.
