Hi David,

This adds optional nvmem consumer properties to the ti,wlink-st device tree
bindings to allow specifying the Bluetooth MAC address.

   See ../clocks/clock-bindings.txt for details.
 - clock-names : Must include the following entry:
   "ext_clock" (External clock provided to the TI combo chip).
+ - nvmem-cells: phandle to nvmem data cell that contains a MAC address
+ - nvmem-cell-names: "mac-address" (required when nvmem-cells is specified)
lets call these “bt-address” since they are not really MAC addresses. They have special formatting etc. Also I prefer that the actual format on how they are stored is described. See Documentation/devicetree/bindings/net/bluetooth.txt for an example.
