+* Clock and reset bindings for CSR atlas7
+
+Required properties:
+- compatible: Should be "sirf,atlas7-car"
+- reg: Address and length of the register set
+- #clock-cells: Should be <1>
+- #reset-cells: Should be <1>
+
+The clock consumer should specify the desired clock by having the clock
+ID in its "clocks" phandle cell.
+The ID list atlas7_clks defined in drivers/clk/sirf/clk-atlas7.c
+
+The reset consumer should specify the desired reset by having the reset
+ID in its "reset" phandle cell.
+The ID list atlas7_reset_unit defined in drivers/clk/sirf/clk-atlas7.c
+
+Examples: Clock and reset controller node:
+
