Subject: [PATCH] dt-bindings: rtc: convert MT7622 RTC to the json-schema
From: Rafał Miłecki <rafal@...ecki.pl>
This helps validating DTS files. Introduced changes:
1. Reworded title
2. Dropper redundant properties descriptions
3. Added required #include-s and adjusted "reg" in example
Signed-off-by: Rafał Miłecki <rafal@...ecki.pl>

-Device-Tree bindings for MediaTek SoC based RTC
-
-Required properties:
-- compatible : Should be
- "mediatek,mt7622-rtc", "mediatek,soc-rtc" : for MT7622 SoC
-- reg : Specifies base physical address and size of the registers;
-- interrupts : Should contain the interrupt for RTC alarm;
-- clocks : Specifies list of clock specifiers, corresponding to
- entries in clock-names property;
-- clock-names : Should contain "rtc" entries
-
-Example:
-
-rtc: rtc@...12800 {
- compatible = "mediatek,mt7622-rtc",
- "mediatek,soc-rtc";
- reg = <0 0x10212800 0 0x200>;
- interrupts = <GIC_SPI 129 IRQ_TYPE_LEVEL_LOW>;
- clocks = <&topckgen CLK_TOP_RTC>;
- clock-names = "rtc";
