+* Adaptrum Anarion Quad SPI controller
+
+Required properties:
+- compatible : Should be "adaptrum,anarion-qspi".
+- reg : Contains two entries, each of which is a tuple consisting of a
+ physical address and length. The first entry is the address and
+ length of the controller register set. The second entry is the
+ address and length of the memory-mapped flash. This second region is
+ the region where the controller responds to XIP requests, and may be
+ larger than the size of the attached flash.
+
+Example:
+
+ qspi: qspi@f200f000 {
+ compatible = "adaptrum,anarion-qspi";
+ reg = <0xf200f000 0x1000>,
+ <0x20000000 0x08000000>;
+
+ flash0: w25q128fvn@0 {
+ ...
+ }
+ };
