[PATCH 1/2] dt-bindings: convert rtc/faraday,ftrtc01 to yaml

From: Corentin Labbe
Date: Mon May 03 2021 - 15:51:00 EST


Converts rtc/faraday,ftrtc01.txt to yaml.
This permits to detect some missing properties: reg, resets, interrupts

-* Faraday Technology FTRTC010 Real Time Clock
-
-This RTC appears in for example the Storlink Gemini family of
-SoCs.
-
-Required properties:
-- compatible : Should be one of:
- "faraday,ftrtc010"
- "cortina,gemini-rtc", "faraday,ftrtc010"
-
-Optional properties:
-- clocks: when present should contain clock references to the
- PCLK and EXTCLK clocks. Faraday calls the later CLK1HZ and
- says the clock should be 1 Hz, but implementers actually seem
- to choose different clocks here, like Cortina who chose
- 32768 Hz (a typical low-power clock).
-- clock-names: should name the clocks "PCLK" and "EXTCLK"
- respectively.
-
-Examples:
-
-rtc@45000000 {
- compatible = "cortina,gemini-rtc";
- reg = <0x45000000 0x100>;
- interrupts = <17 IRQ_TYPE_LEVEL_HIGH>;
- clocks = <&foo 0>, <&foo 1>;
- clock-names = "PCLK", "EXTCLK";
-};
