This helps validating DTS files. Introduced changes:
1. Documented "reg" property
2. Dropped "syscon" as it was incorrectly used
3. Adjusted nodename, "compatible" and "reg" in example

-MediaTek PCIESYS controller
-============================
-
-The MediaTek PCIESYS controller provides various clocks to the system.
-
-Required Properties:
-
-- compatible: Should be:
-	- "mediatek,mt7622-pciesys", "syscon"
-	- "mediatek,mt7629-pciesys", "syscon"
-- #clock-cells: Must be 1
-- #reset-cells: Must be 1
-
-The PCIESYS 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:
-
-pciesys: pciesys@1a100800 {
-	compatible = "mediatek,mt7622-pciesys", "syscon";
-	reg = <0 0x1a100800 0 0x1000>;
-	#clock-cells = <1>;
-	#reset-cells = <1>;
-};
