The USB host nodes are removed, that is, the USB host is disabled. 2. The gpio_keys node is added to wake up from the sleep. 3. The sama5d3xdm.dtsi isn't included, because the pins for LCD are conflicted with one for gpio_keys. As said in errata, "When the USB host ports are used in high speed mode (EHCI), it is not possible to suspend the ports if no device is attached on each port. This leads to increased power consumption even if the system is in a low power mode." That is why the the USB host isn't enabled.
