[v2] dt-bindings: arm: mediatek: convert MT7622-related bindings to the json-schema

[PATCH V2 1/3] dt-bindings: arm: mediatek: convert hifsys to the json-schema clock

Posted by Rafał Miłecki 7 months, 2 weeks ago

From: Rafał Miłecki <rafal@milecki.pl>

This helps validating DTS files. Introduced changes:
1. Documented "reg" property
2. Documented "#reset-cells" property
3. Dropped "syscon" as it was incorrectly used
4. Adjusted "compatible" and "reg" in example

-Mediatek hifsys controller
-============================
-
-The Mediatek hifsys controller provides various clocks and reset
-outputs to the system.
-
-Required Properties:
-
-- compatible: Should be:
-	- "mediatek,mt2701-hifsys", "syscon"
-	- "mediatek,mt7622-hifsys", "syscon"
-	- "mediatek,mt7623-hifsys", "mediatek,mt2701-hifsys", "syscon"
-- #clock-cells: Must be 1
-
-The hifsys 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:
-
-hifsys: clock-controller@1a000000 {
-	compatible = "mediatek,mt2701-hifsys", "syscon";
-	reg = <0 0x1a000000 0 0x1000>;
-	#clock-cells = <1>;
-	#reset-cells = <1>;

Same here, "The MediaTek HIFSYS controller..."

Yeah, that's right, let's prefer "clock and reset controller", as this binding does
describe exactly only those two functionalities of the whole HIFSYS block.

If there is going to be resend, drop items here, it's just an enum.
