ISSUE 1: USB
Description
- Stopped working after switching from 3.10 to 4.0 kernel
Config
- kernel: 4.0 (linux-xlnx 468329e7fac2b22e76897fbd40532cc0884ded2a)
- new device tree record:
...
ps7_usb_0: ps7-usb@e0002000 {
clocks = <&clkc 28>;
compatible = "xlnx,zynq-usb-2.20a", "chipidea,usb2";
reg = <0xe0002000 0x1000>;
interrupt-parent = <&ps7_scugic_0>;
interrupts = <0 21 4>;
dr_mode = "host";
phy_type = "ulpi";
usb-phy = <&usb_phy0>;
} ;
...
} ;
...
usb_phy0: phy0{
compatible = "ulpi-phy";
#phy-cells = <0>;
reg = <0xe0002000 0x1000>;
viewport = <0x170>;
} ;
- .config
CONFIG_USB_ULPI=y CONFIG_USB_ULPI_VIEWPORT=y CONFIG_USB_CHIPIDEA_DEBUG=y CONFIG_USB_GPIO_VBUS=n CONFIG_USB_OTG=n /*do not care if dr_mode = "host";*/ CONFIG_USB_GADGET=n
Log
- dmesg:
[ 1.035759] ehci_hcd: USB 2.0 'Enhanced' Host Controller (EHCI) Driver [ 1.042319] usbcore: registered new interface driver usb-storage [ 1.073619] e0002000.ps7-usb supply vbus not found, using dummy regulator [ 1.103560] Registering platform device 'ci_hdrc.0'.

a: vbus not found
- the problem is not critical
b: unable to init phy: -110
- Zynq Linux USB Device Driver - typo in docs but it's correct in the released image
- note: order in the device tree does not matter
- corrected the device tree record (s/viewport/view-port/):
usb_phy0: phy0{
compatible = "ulpi-phy";
#phy-cells = <0>;
reg = <0xe0002000 0x1000>;
view-port = <0x170>;
} ;
Links
- Zynq Linux USB Device Driver - typo came from here.
- A discussion.
- Forgot the contents, probably unrelated
ISSUE 2: VSC330X
- Config and the kernel are the same as in ISSUE 1
Log
- dmesg:
[ 1.069904] vsc330x 0-0001: vsc330x_i2c_probe:841 error writing [ 1.075745] vsc330x: probe of 0-0001 failed with error -5
Reason
- 10398 board, that has it, is not connected, that's it.
