-AXM5516 clock driver bindings
------------------------------
-
-Required properties :
-- compatible : shall contain "lsi,axm5516-clks"
-- reg : shall contain base register location and length
-- #clock-cells : shall contain 1
-
-The consumer specifies the desired clock by having the clock ID in its "clocks"
-phandle cell. See <dt-bindings/clock/lsi,axxia-clock.h> for the list of
-supported clock IDs.
-
-Example:
-
-	clks: clock-controller@2010020000 {
-		compatible = "lsi,axm5516-clks";
-		#clock-cells = <1>;
-		reg = <0x20 0x10020000 0 0x20000>;
-	};
-
-	serial0: uart@2010080000 {
-		compatible = "arm,pl011", "arm,primecell";
-		reg = <0x20 0x10080000 0 0x1000>;
-		interrupts = <GIC_SPI 56 IRQ_TYPE_LEVEL_HIGH>;
-		clocks = <&clks AXXIA_CLK_PER>;
-		clock-names = "apb_pclk";
-	};
-																																};
