Hi, I'm new to device tree, the following code is from `imx8-ss-conn.dtsi`:
usbotg1: usb@5b0d0000 {
compatible = "fsl,imx8qm-usb", "fsl,imx7ulp-usb",
"fsl,imx27-usb";
reg = <0x5b0d0000 0x200>;
interrupt-parent = <&gic>;
interrupts = <GIC_SPI 267 IRQ_TYPE_LEVEL_HIGH>;
fsl,usbphy = <&usbphy1>;
fsl,usbmisc = <&usbmisc1 0>;
clocks = <&usb2_lpcg 0>;
ahb-burst-config = <0x0>;
tx-burst-size-dword = <0x10>;
rx-burst-size-dword = <0x10>;
power-domains = <&pd IMX_SC_R_USB_0>;
status = "disabled";
};
I'd like to get some information about the reg value, here is "usbotg1: usb@5b0d0000" .
Where is the value of "5b0d0000" from? from some document? some calculation?
