[PATCH v1 0/1] riscv: dts: starfive: jh7110-pine64-star64: enable usb0 host function

Posted by E Shattow 2 weeks, 1 day ago

Enable host mode JH7110 on-chip USB for Pine64 Star64 by setting host mode
and connect vbus pinctrl.

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 usb configuration fails (same as it is now).
