+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 SoC.
+
+Required properties:
+- compatible: should be
+ "hisilicon,hi3660-reset"
+- hisi,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@ffd7e000 {
+ compatible = "hisilicon,hi3660-iomcu", "syscon";
+ reg = <0x0 0xffd7e000 0x0 0x1000>;
+ };
+
+ iomcu_rst: iomcu_rst_controller {
+ compatible = "hisilicon,hi3660-reset";
+ hisi,rst-syscon = <&iomcu>;
+ #reset-cells = <2>;
+ };
+
+Specifying reset lines connected to IP modules
+==============================================
+example:
+
+ i2c0: i2c@..... {
+ ...
+ resets = <&iomcu_rst 0x20 3>; /* offset: 0x20; bit: 3 */
+ ...
+ };
