Subject: [PATCH v4 0/7] Add JH7110 USB and USB PHY driver support

This patchset adds USB driver and USB PHY for the StarFive JH7110 SoC.
USB work mode is peripheral and using USB 2.0 PHY in VisionFive 2 board.
The patch has been tested on the VisionFive 2 board.

This patchset should be applied after the patchset [1], [2] and[3]:
[1] https://patchwork.kernel.org/project/linux-riscv/cover/20230314124404.117592-1-xingyu.wu@starfivetech.com/
[2] https://lore.kernel.org/all/20230315055813.94740-1-william.qiu@starfivetech.com/
[3] https://patchwork.kernel.org/project/linux-phy/cover/20230315100421.133428-1-changhuang.liang@starfivetech.com/

This patchset is base on v6.3-rc4

patch 1 is usb phy dt-binding document.
patch 2 is Pcie PHY dt-binding document.
patch 3 is USB 2.0 PHY driver.
patch 4 is PCIe PHY driver.
patch 5 is usb dt-binding document.
patch 6 is the wrapper module driver of Cadence USB3. USB controller IP is Cadence USB3.
patch 7 is USB device tree configuration.
