   4 Subject: [PATCH] ARM: dts: bcm53016: Add devicetree for D-Link DWL-8610AP
   5
   6 This adds a device tree for the BCM53016-based D-Link DWL-8610AP
   7 access point wireless router.
   8
   9 The TRX-format partitions had to be named "firmware" due to
  10 an OpenWrt patch that only accepts parting such nodes if they
  11 are named "firmware".
