-Hisilicon System Reset Controller
-======================================
-
-Please also refer to reset.txt in this directory for common reset
-controller binding usage.
-
-The reset controller registers are part of the system-ctl block on
-hi3660 and hi3670 SoCs.
-
-Required properties:
-- compatible: should be one of the following:
-		 "hisilicon,hi3660-reset" for HI3660
-		 "hisilicon,hi3670-reset", "hisilicon,hi3660-reset" for HI3670
-- hisilicon,rst-syscon: phandle of the reset's syscon.
-- #reset-cells : Specifies the number of cells needed to encode a
-  reset source.  The type shall be a <u32> and the value shall be 2.
-
-	 Cell #1 : offset of the reset assert control
-	           register from the syscon register base
-		   offset + 4: deassert control register
-		   offset + 8: status control register
-	 Cell #2 : bit position of the reset in the reset control register
-
-Example:
-	iomcu: iomcu at ffd7e000 {
-		compatible = "hisilicon,hi3660-iomcu", "syscon";
-		reg = <0x0 0xffd7e000 0x0 0x1000>;
-	};
-
-	iomcu_rst: iomcu_rst_controller {
-		compatible = "hisilicon,hi3660-reset";
-		hisilicon,rst-syscon = <&iomcu>;
-		#reset-cells = <2>;
-	};
-
-Specifying reset lines connected to IP modules
-==============================================
-example:
-
-        i2c0: i2c at ..... {
-                ...
-		resets = <&iomcu_rst 0x20 3>; /* offset: 0x20; bit: 3 */
-                ...
-        };
