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). On Milk-V Mars with four USB-A ports this applies to one of the ports and the remaining three VL805-connected ports via PCIe are not changed. Changes since v4: - Rebase on latest master Changes since v3: - Rebase on linux-next/master - use tabs for code indent Changes since v2: - Rebase on 6.12 E Shattow (1): riscv: dts: starfive: jh7110-milkv-mars: enable usb0 host function .../boot/dts/starfive/jh7110-milkv-mars.dts | 18 +++++++++++++++++- 1 file changed, 17 insertions(+), 1 deletion(-)
