+Oxford Semiconductor OXNAS SoC Family Standard Clocks
+================================================
+
+Please also refer to clock-bindings.txt in this directory for common clock
+bindings usage.
+
+Required properties:
+- compatible: Should be "oxsemi,ox810se-stdclk"
+- #clock-cells: 1, see below
+
+Parent node should have the following properties :
+- compatible: Should be "oxsemi,ox810se-sys-ctrl", "syscon", "simple-mfd"
+
+For OX810SE, the clock indices are :
+ - 0: LEON
+ - 1: DMA_SGDMA
+ - 2: CIPHER
+ - 3: SATA
+ - 4: AUDIO
+ - 5: USBMPH
+ - 6: ETHA
+ - 7: PCIA
+ - 8: NAND
+
+example:
+
+sys: sys-ctrl@000000 {
+       compatible = "oxsemi,ox810se-sys-ctrl", "syscon", "simple-mfd";
+       reg = <0x000000 0x100000>;
+
+       stdclk: stdclk {
+               compatible = "oxsemi,ox810se-stdclk";
+               #clock-cells = <1>;
+       };
+};
