   4 Subject: [PATCH 13/31] ARM: dts: Add basic devicetree for D-Link DNS-313
   5
   6 This adds a basic device tree for the D-Link DNS-313
   7 NAS enclosure. This device has a thermal sensor and a
   8 fan so we add a thermal zone for the chassis in the
   9 device tree based on information from the product.
