   4 Subject: [PATCH] dt-bindings: arm: mediatek: move ethsys controller & convert
   5  to DT schema
   6 MIME-Version: 1.0
   7 Content-Type: text/plain; charset=UTF-8
   8 Content-Transfer-Encoding: 8bit

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

  28 -Mediatek ethsys controller
  29 -============================
  30 -
  31 -The Mediatek ethsys controller provides various clocks to the system.
  32 -
  33 -Required Properties:
  34 -
  35 -- compatible: Should be:
  36 -       - "mediatek,mt2701-ethsys", "syscon"
  37 -       - "mediatek,mt7622-ethsys", "syscon"
  38 -       - "mediatek,mt7623-ethsys", "mediatek,mt2701-ethsys", "syscon"
  39 -       - "mediatek,mt7629-ethsys", "syscon"
  40 -       - "mediatek,mt7981-ethsys", "syscon"
  41 -       - "mediatek,mt7986-ethsys", "syscon"
  42 -- #clock-cells: Must be 1
  43 -- #reset-cells: Must be 1
  44 -
  45 -The ethsys controller uses the common clk binding from
  46 -Documentation/devicetree/bindings/clock/clock-bindings.txt
  47 -The available clocks are defined in dt-bindings/clock/mt*-clk.h.
  48 -
  49 -Example:
  50 -
  51 -ethsys: clock-controller@1b000000 {
  52 -       compatible = "mediatek,mt2701-ethsys", "syscon";
  53 -       reg = <0 0x1b000000 0 0x1000>;
  54 -       #clock-cells = <1>;
  55 -       #reset-cells = <1>;
