3 * Device tree for D-Link DIR-890L
4 * D-Link calls this board "WRGAC36"
5 * this router has the same looks and form factor as D-Link DIR-885L.
6 *
7 * Some differences from DIR-885L include a separate USB2 port, separate LEDs
8 * for USB2 and USB3, a separate VCC supply for the USB2 slot and no
9 * router/extender switch is mounted (there is an empty mount point on the
10 * PCB) so this device is a pure router. Also the LAN ports are in the right
11 * order.
12 *
13 * Based on the device tree for DIR-885L
