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.
1. usb pin setting
usb_pins: usb0-0 {
driver-vbus-pin {
pinmux = <GPIOMUX(25, GPOUT_SYS_USB_DRIVE_VBUS,
GPOEN_ENABLE,
GPI_NONE)>;
bias-disable;
input-disable;
input-schmitt-disable;
slew-rate = <0>;
};
};
2. related dts node setting.
&pcie0 {
status = "disabled";
};
&pciephy0 {
starfive,sys-syscon = <&sys_syscon 0x18>;
starfive,stg-syscon = <&stg_syscon 0x148 0x1f4>;
status = "okay";
};
&usb0 {
pinctrl-names = "default";
pinctrl-0 = <&usb_pins>;
status = "okay";
};
&usb_cdns3 {
phys = <&usbphy0>, <&pciephy0>;
phy-names = "cdns3,usb2-phy", "cdns3,usb3-phy";
dr_mode = "host";
status = "okay";
};
- previous version
v1:
https://patchwork.ozlabs.org/project/uboot/cover/20240504150358.19600-1-minda.c...@starfivetech.com/
- patch description.
patch1: Add set phy mode function in cdns3 core driver
which is used by Starfive JH7110.
patch2-3: USB and PCIe 2.0 (usb 3.0) PHY drivier
patch4: Cadence USB wrapper driver.
patch5: Add JH7110 USB default overcurrent pin.
patch6-8 dts, config and maintainers update.
- change:
v2:
- patch 1 Move the added code to cdns3_core_init_role(). Must
set PHY mode before calling cdns3 role start function.
- patch 1-4 correct the code format.(follow Marek's comments.)
- patch 2 Add set 125M clock in PHY init function.
- Add new patch5.
