Subject: [PATCH v6 1/1] riscv: dts: starfive: jh7110-milkv-mars: enable usb0 host function
Date: Wed, 27 Nov 2024 07:49:23 -0800	[thread overview]
Message-ID: <20241127154958.71094-2-e@freeshell.de> (raw)
In-Reply-To: <20241127154958.71094-1-e@freeshell.de>

Milk-V Mars board routes one of four USB-A ports to USB0 on the SoC
rather than to the VL805 USB 3.0 <-> PCIe chip.
Set JH7110 on-chip USB host mode and vbus pin assignment accordingly.
