Thanks for your patch!

Please keep similar nodes together, i.e.

    phyrst: usbphy-ctrl at 11e00000 {
    ohci0: usb at 11e10000 {
    ohci1: usb at 11e30000 {
    ehci0: usb at 11e10100 {
    ehci1: usb at 11e30100 {
    usb2_phy0: usb-phy at 11e10200 {
    usb2_phy1: usb-phy at 11e30200 {
    hsusb: usb at 11e20000 {

After that, you can easily compare with similar SoCs:

    soc-dts-diff arch/arm64/boot/dts/renesas/r9a0{7g044,8g045}.dtsi
