+Binding for LOONGSON LS7A SPI controller
+
+Required properties:
+- compatible: should be "pci0014,7a0b.0","pci0014,7a0b","pciclass088000","pciclass0880".
+- reg: reference IEEE Std 1275-1994.
+- #address-cells: <1>, as required by generic SPI binding.
+- #size-cells: <0>, also as required by generic SPI binding.
+- #interrupts: No hardware interrupt.
+
+Child nodes as per the generic SPI binding.
+
+Example:
+
+ spi@16,0 {
+ compatible = "pci0014,7a0b.0",
+ "pci0014,7a0b",
+ "pciclass088000",
+ "pciclass0880";
+
+ #address-cells = <1>;
+ #size-cells = <0>;
+ reg = <0xb000 0x0 0x0 0x0 0x0>;
+ num-chipselects = <0>;
+ spiflash: s25fl016k@0 {
+ #address-cells = <1>;
+ #size-cells = <1>;
+ compatible ="spansion,s25fl016k","jedec,spi-nor";
+ spi-max-frequency=<50000000>;
+ reg=<0>;
+ };
+ };
