From: Minda Chen
Date: Thu Jun 29 2023 - 03:53:54 EST


This patchset adds USB and PCIe PHY for the StarFive JH7110 SoC.
The patch has been tested on the VisionFive 2 board.

This patchset is base on v6.4-rc6

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 PCIe PHY dts

Previous version are merged with USB controller patch.
For USB controller patch is accepted. Now remove the USB controller patch.
And remove the dependency.

previous change can be seen list below.

1. (patch 1) split PCIe PHY dt-binding doc to patch 2.
2. (patch 2) PCIe PHY add stg and sys con configuration to dt-binding doc.
3. (patch 3)
- split PCIe PHY driver to patch 4.
- replace dr_mode to phy mode in jh7110_usb2_phy.
4. (patch 4)
- Makefile and Kconfig sorted by alphabet sequence.
- Add PCIe PHY stg and syscon PHY connection configuration
for USB 3.0.

v3:
1. Add patch 1 - 4. Add USB PHY driver and dt-binding doc.
USB PHY codes are moved to patch 3 and patch 4.
