This functionality depends on setting the USB over-current register to disable at bootloader phase, for example U-Boot: https://patchwork.ozlabs.org/project/uboot/patch/20241012031328.4268-6-minda.chen@starfivetech.com/ If the over-current register is not prepared for us then the result is no change in functional outcome with this patch applied; there is an error visible to the user and this additional usb configuration fails (same as it is now). The existing three VL805 connected USB ports via PCIe on Milk-V Mars are not affected. Changes since v2: - Rebase on 6.12 Changes since v1: - series name (was "[PATCH] riscv: dts: starfive: jh7110-milkv-mars: set host mode and vbus pin for on-chip USB 2.0") - adjust pin label to obey dtschema - use cover letter E Shattow (1): riscv: dts: starfive: jh7110-milkv-mars: enable usb0 host function .../boot/dts/starfive/jh7110-milkv-mars.dts | 21 +++++++++++++++++++ 1 file changed, 21 insertions(+)
