Subject: [PATCH v3 4/5] arm64: dts: rockchip: Enable USB 2.0 ports on ArmSoM Sige1

From: Heiko Stuebner <[email-masked]>
Date: Fri, 29 May 2026 01:23:57 +0200

From: Jonas Karlman <[email-masked]>

The ArmSoM Sige1 has two USB 2.0 Type-A HOST ports behind an onboard
USB hub, and one USB 2.0 Type-C OTG port.

Add support for using the USB 2.0 ports on ArmSoM Sige1.

The onboard USB hub handles OHCI so only the EHCI controller is enabled.
