From: Sebastian Reichel Date: Tue, 19 Aug 2025 14:50:13 +0000 (+0200) Subject: arm64: dts: rockchip: add USB-C support for ROCK 5B/5B+/5T X-Git-Tag: v6.18-rc1~147^2~47^2~26 X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=67b2c15d8fb3c1447a23358075e4f336d40d9797;p=thirdparty%2Flinux.git arm64: dts: rockchip: add USB-C support for ROCK 5B/5B+/5T Add hardware description for the USB-C port in the Radxa ROCK 5 Model B family. This describes the OHCI, EHCI and XHCI USB parts. The DisplayPort AltMode is only partially described, as bindings for the necessary DisplayPort controller are still being reviewed.
