Subject: [PATCH] dt-bindings: arm: mediatek: move ethsys controller & convert
|
|
to DT schema
|
|
MIME-Version: 1.0
|

Content-Type: text/plain; charset=UTF-8

DT schema helps validating DTS files. Binding was moved to clock/ as
|
|
this hardware is a clock provider. Example required a small fix for
|
|
"reg" value (1 address cell + 1 size cell).

-Mediatek ethsys controller
|
|
-============================
|
|
-
|
|
-The Mediatek ethsys controller provides various clocks to the system.
|
|
-
|
|
-Required Properties:
|
|
-
|
|
-- compatible: Should be:
|
|
- - "mediatek,mt2701-ethsys", "syscon"
|
|
- - "mediatek,mt7622-ethsys", "syscon"
|
|
- - "mediatek,mt7623-ethsys", "mediatek,mt2701-ethsys", "syscon"
|
|
- - "mediatek,mt7629-ethsys", "syscon"
|
|
- - "mediatek,mt7981-ethsys", "syscon"
|
|
- - "mediatek,mt7986-ethsys", "syscon"
|
|
-- #clock-cells: Must be 1
|
|
-- #reset-cells: Must be 1
|
|
-
|
|
-The ethsys 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:
|
|
-
|
|
-ethsys: clock-controller@1b000000 {
|
|
- compatible = "mediatek,mt2701-ethsys", "syscon";
|
|
- reg = <0 0x1b000000 0 0x1000>;
|
|
- #clock-cells = <1>;
|
|
- #reset-cells = <1>;
|
|
-};
