Subject: [PATCH v2 3/3] dt-bindings: arm: mediatek: infracfg: Convert to DT schema
From: Yassine Oudjana <y.oudjana@...tonmail.com>
Convert infracfg bindings to DT schema format. Not all drivers
currently implement resets, so #reset-cells is made a required
property only for those that do. Using power-controller in the
example node name makes #power-domain-cells required causing
a dt_binding_check error. To solve this, the node is renamed to
syscon@...01000.

-Mediatek infracfg controller
-============================
-
-The Mediatek infracfg controller provides various clocks and reset
-outputs to the system.
-
-Required Properties:
-
-- compatible: Should be one of:
- - "mediatek,mt2701-infracfg", "syscon"
- - "mediatek,mt2712-infracfg", "syscon"
- - "mediatek,mt6765-infracfg", "syscon"
- - "mediatek,mt6779-infracfg_ao", "syscon"
- - "mediatek,mt6797-infracfg", "syscon"
- - "mediatek,mt7622-infracfg", "syscon"
- - "mediatek,mt7623-infracfg", "mediatek,mt2701-infracfg", "syscon"
- - "mediatek,mt7629-infracfg", "syscon"
- - "mediatek,mt7986-infracfg", "syscon"
- - "mediatek,mt8135-infracfg", "syscon"
- - "mediatek,mt8167-infracfg", "syscon"
- - "mediatek,mt8173-infracfg", "syscon"
- - "mediatek,mt8183-infracfg", "syscon"
- - "mediatek,mt8516-infracfg", "syscon"
-- #clock-cells: Must be 1
-- #reset-cells: Must be 1
-
-The infracfg 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.
-Also it uses the common reset controller binding from
-Documentation/devicetree/bindings/reset/reset.txt.
-The available reset outputs are defined in
-dt-bindings/reset/mt*-resets.h
-
-Example:
-
-infracfg: power-controller@...01000 {
- compatible = "mediatek,mt8173-infracfg", "syscon";
- reg = <0 0x10001000 0 0x1000>;
- #clock-cells = <1>;
- #reset-cells = <1>;
-};
