-Device Tree Clock bindings for arch-rockchip
-
-This binding uses the common clock binding[1].
-
-[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
-
-== Gate clocks ==
-
-These bindings are deprecated!
-Please use the soc specific CRU bindings instead.
-
-The gate registers form a continuos block which makes the dt node
-structure a matter of taste, as either all gates can be put into
-one gate clock spanning all registers or they can be divided into
-the 10 individual gates containing 16 clocks each.
-The code supports both approaches.
-
-Required properties:
-- compatible : "rockchip,rk2928-gate-clk"
-- reg : shall be the control register address(es) for the clock.
-- #clock-cells : from common clock binding; shall be set to 1
-- clock-output-names : the corresponding gate names that the clock controls
-- clocks : should contain the parent clock for each individual gate,
-  therefore the number of clocks elements should match the number of
-  clock-output-names
-
-Example using multiple gate clocks:
-
-		clk_gates0: gate-clk@200000d0 {
-			compatible = "rockchip,rk2928-gate-clk";
-			reg = <0x200000d0 0x4>;
