Opps, I was all kinds of confused then. So, before I submit a V4, here is my understanding: drivers/.../common.c * contains -only- '.compatible = "renesas,rza1-usbhs"' Documentation/.../renesas_usbhs.txt * contains both "renesas,usbhs-r7s72100" and "renesas,rza1-usbhs" r7s72100.dtsi * usbhs0: usb@e8010000 { compatible = "renesas,usbhs-r7s72100", "renesas,rza1-usbhs"; Is this correct? Thanks, Chris
