   4 Subject: [PATCH] ARM: dts: bcm47094: Add devicetree for D-Link DIR-890L
   5
   6 This adds a device tree for the D-Link DIR-890L. This device
   7 is very similar to D-Link DIR-885L, the differences are detailed
   8 as a comment in the DTS file.

  37 + *
  38 + * Some differences from DIR-885L include a separate USB2 port, separate LEDs
  39 + * for USB2 and USB3, a separate VCC supply for the USB2 slot and no
  40 + * router/extender switch is mounted (there is an empty mount point on the
  41 + * PCB) so this device is a pure router. Also the LAN ports are in the right
  42 + * order.
