Below are codes for accessing usb sysif_regs in driver: usb_sys_regs = (struct usb_sys_interface *) ((u32)dr_regs + USB_DR_SYS_OFFSET); these codes work in 32-bit, but in 64-bit, use u32 to type cast the address of ioremap is not right, and accessing members of 'usb_sys_regs' will cause call trace, so use unsigned long for both 32-bit and 64-bit.
