[PATCH V3 2/3] dt-bindings: arm: mediatek: convert PCIESYS to the json-schema clock

From: Rafał Miłecki
Date: Sun Feb 11 2024 - 16:40:10 EST


From: Rafał Miłecki <rafal@xxxxxxxxxx>

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>;
-};
