Add Starfive JH7110 Cadence USB driver and related PHY driver.
So the codes can be used in visionfive2 and star64 7110 board.
The driver is almost the same with kernel driver.
Test with Star64 JH7110 board USB 3.0 + USB 2.0 host.
The code can work.
- Star64 using USB 3.0 and USB 2.0 host must add below board dts setting.
Does this mean a future patch for spl_fdt_fixup_star64() is needed?
Did you also have a look at the USB on the Milk V Mars CM?
Best regards
