Subject: [PATCH V2 1/3] dt-bindings: timer: Convert i.MX GPT to json-schema
Date: Tue, 19 May 2020 11:55:45 +0800 [thread overview]
Message-ID: <1589860547-3207-2-git-send-email-Anson.Huang@nxp.com> (raw)
In-Reply-To: <1589860547-3207-1-git-send-email-Anson.Huang@nxp.com>
Convert the i.MX GPT binding to DT schema format using json-schema.
Signed-off-by: Anson Huang <Anson.Huang@nxp.com>

-Freescale i.MX General Purpose Timer (GPT)
-
-Required properties:
-
-- compatible : should be one of following:
- for i.MX1:
- - "fsl,imx1-gpt";
- for i.MX21:
- - "fsl,imx21-gpt";
- for i.MX27:
- - "fsl,imx27-gpt", "fsl,imx21-gpt";
- for i.MX31:
- - "fsl,imx31-gpt";
- for i.MX25:
- - "fsl,imx25-gpt", "fsl,imx31-gpt";
- for i.MX50:
- - "fsl,imx50-gpt", "fsl,imx31-gpt";
- for i.MX51:
- - "fsl,imx51-gpt", "fsl,imx31-gpt";
- for i.MX53:
- - "fsl,imx53-gpt", "fsl,imx31-gpt";
- for i.MX6Q:
- - "fsl,imx6q-gpt", "fsl,imx31-gpt";
- for i.MX6DL:
- - "fsl,imx6dl-gpt";
- for i.MX6SL:
- - "fsl,imx6sl-gpt", "fsl,imx6dl-gpt";
- for i.MX6SX:
- - "fsl,imx6sx-gpt", "fsl,imx6dl-gpt";
-- reg : specifies base physical address and size of the registers.
-- interrupts : should be the gpt interrupt.
-- clocks : the clocks provided by the SoC to drive the timer, must contain
- an entry for each entry in clock-names.
-- clock-names : must include "ipg" entry first, then "per" entry.
-
-Example:
-
-gpt1: timer@10003000 {
- compatible = "fsl,imx27-gpt", "fsl,imx21-gpt";
- reg = <0x10003000 0x1000>;
- interrupts = <26>;
- clocks = <&clks IMX27_CLK_GPT1_IPG_GATE>,
- <&clks IMX27_CLK_PER1_GATE>;
- clock-names = "ipg", "per";
-};
