Hello,
What is the right way for using the new cdns3-imx glue usb driver on a
imx8qm soc with linux-next. I added this snippet in imx8qm.dtsi and
enabled the driver in the kernel configuration.
usbotg3: usb3@5b110000 {
compatible = "cdns,usb3";
reg = <0x0 0x5B110000 0x0 0x10000>,
<0x0 0x5B130000 0x0 0x10000>,
<0x0 0x5B140000 0x0 0x10000>,
<0x0 0x5B160000 0x0 0x40000>,
<0x0 0x5B120000 0x0 0x10000>;
interrupt-parent = <&gic>;
interrupts = <GIC_SPI 271 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&usb3_lpcg 1>,
<&usb3_lpcg 0>,
<&usb3_lpcg 5>,
<&usb3_lpcg 2>,
<&usb3_lpcg 3>;
clock-names = "usb3_lpm_clk", "usb3_bus_clk", "usb3_aclk",
"usb3_ipg_clk", "usb3_core_pclk";
assigned-clocks = <&clk IMX_SC_R_USB_2 IMX_SC_PM_CLK_PER>,
<&clk IMX_SC_R_USB_2 IMX_SC_PM_CLK_MISC>,
<&clk IMX_SC_R_USB_2 IMX_SC_PM_CLK_MST_BUS>;
assigned-clock-rates = <125000000>, <12000000>, <250000000>;
power-domains = <&pd IMX_SC_R_USB_2>;
cdns3,usbphy = <&usb3phynop1>;
status = "disabled";
};
In board dts I enabled this:
&usbotg3 {
dr_mode = "host";
status = "okay";
};
On probing I got:
[ 2.932089] cdns-usb3 5b110000.usb3: missing host IRQ
I also tried to enable "fsl,imx8qm-usb3" compatible buts this results
directly into a crash.
What do I miss here? some comments would be helpful.
Best Regards,
Oliver
