Subject: [PATCH 09/11] arm64: dts: rockchip: Enable USB 2.0 ports on Radxa ROCK 2A/2F
Date: Wed, 23 Jul 2025 12:23:07 +0000 [thread overview]
Message-ID: <20250723122323.2344916-10-jonas@kwiboo.se> (raw)
In-Reply-To: <20250723122323.2344916-1-jonas@kwiboo.se>
The ROCK 2A has three USB 2.0 Type-A HOST ports behind an onboard
USB hub, and one USB 3.0 Type-A port.
And the ROCK 2F 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 Radxa ROCK 2A/2F.
The onboard USB hub handles OHCI so only the EHCI controller is enabled.
