-MediaTek g3dsys controller
-============================
-
-The MediaTek g3dsys controller provides various clocks and reset controller to
-the GPU.
-
-Required Properties:
-
-- compatible: Should be:
-	- "mediatek,mt2701-g3dsys", "syscon":
-		for MT2701 SoC
-	- "mediatek,mt7623-g3dsys", "mediatek,mt2701-g3dsys", "syscon":
-		for MT7623 SoC
-- #clock-cells: Must be 1
-- #reset-cells: Must be 1
-
-The g3dsys controller uses the common clk binding from
-Documentation/devicetree/bindings/clock/clock-bindings.txt
-The available clocks are defined in dt-bindings/clock/mt*-clk.h.
-
-Example:
-
-g3dsys: clock-controller@13000000 {
-	compatible = "mediatek,mt7623-g3dsys",
-		     "mediatek,mt2701-g3dsys",
-		     "syscon";
-	reg = <0 0x13000000 0 0x200>;
-	#clock-cells = <1>;
-	#reset-cells = <1>;
-};
