Subject: [PATCH 2/3] dt-bindings: arm: mediatek: apmixedsys: Convert to DT schema

From: Yassine Oudjana <y.oudjana@...tonmail.com>

Convert apmixedsys bindings to DT schema format. MT2701, MT7623 and
MT7629 device trees currently have the syscon compatible without
it being mentioned in the old DT bindings file which introduces
dtbs_check errors when converting to DT schema as-is, so
mediatek,mt2701-apmixedsys and mediatek,mt7629-apmixedsys are placed
in the last items list with the syscon compatible, and syscon is
added to the mediatek,mt7623-apmixedsys list.

-Mediatek apmixedsys controller
-==============================
-
-The Mediatek apmixedsys controller provides the PLLs to the system.
-
-Required Properties:
-
-- compatible: Should be one of:
-	- "mediatek,mt2701-apmixedsys"
-	- "mediatek,mt2712-apmixedsys", "syscon"
-	- "mediatek,mt6765-apmixedsys", "syscon"
-	- "mediatek,mt6779-apmixedsys", "syscon"
-	- "mediatek,mt6797-apmixedsys"
-	- "mediatek,mt7622-apmixedsys"
-	- "mediatek,mt7623-apmixedsys", "mediatek,mt2701-apmixedsys"
-	- "mediatek,mt7629-apmixedsys"
-	- "mediatek,mt7986-apmixedsys"
-	- "mediatek,mt8135-apmixedsys"
-	- "mediatek,mt8167-apmixedsys", "syscon"
-	- "mediatek,mt8173-apmixedsys"
-	- "mediatek,mt8183-apmixedsys", "syscon"
-	- "mediatek,mt8516-apmixedsys"
-- #clock-cells: Must be 1
-
-The apmixedsys 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:
-
-apmixedsys: clock-controller@...09000 {
-	compatible = "mediatek,mt8173-apmixedsys";
-	reg = <0 0x10209000 0 0x1000>;
-	#clock-cells = <1>;
-};
