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

-Mediatek hifsys controller
-============================
-
-The Mediatek hifsys controller provides various clocks and reset
-outputs to the system.
-
-Required Properties:
-
-- compatible: Should be:
- - "mediatek,mt2701-hifsys", "syscon"
- - "mediatek,mt7622-hifsys", "syscon"
- - "mediatek,mt7623-hifsys", "mediatek,mt2701-hifsys", "syscon"
-- #clock-cells: Must be 1
-
-The hifsys 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:
-
-hifsys: clock-controller@1a000000 {
- compatible = "mediatek,mt2701-hifsys", "syscon";
- reg = <0 0x1a000000 0 0x1000>;
- #clock-cells = <1>;
- #reset-cells = <1>;
-};

Please, "MediaTek HIFSYS controller"

Them maybe "clock controller" or "clock and reset controller"?

Yeah, that's right, let's prefer "clock and reset controller", as this binding does
describe exactly only those two functionalities of the whole HIFSYS block.

Cheers,
Angelo
