+TI syscon gate clock
+
+The gate clock node must be provided inside a system controller node.
+
+Required:
+- comaptible: Must be "ti,syscon-gate-clock"
+- reg: Offset of register that controls the clock within syscon regmap
+- ti,clock-bit-idx: bit index that control gate/ungating of clock
+- clocks: phandle to the clock parent
+- #clock-cells: must be <0>
+
+Example:
+ ctrlmmr_epwm_ctrl: syscon@104140{
+ compatible = "syscon", "simple-bus";
+ reg = <0x0 0x104140 0x0 0x18>;
+ ranges = <0x0 0x0 0x104140>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ ehrpwm0_tbclk: clk@0 {
+ compatible = "ti,syscon-gate-clock";
+ reg = <0x0>;
+ #clock-cells = <0>;
+ clocks = <&k3_clks 40 0>;
+ ti,clock-bit-idx = <0>;
+ };
+
+ ehrpwm1_tbclk: clk@4 {
+ compatible = "ti,syscon-gate-clock";
+ reg = <0x4>;
+ #clock-cells = <0>;
+ clocks = <&k3_clks 41 0>;
+ ti,clock-bit-idx = <0>;
+ };
+ };
