Subject: [PATCH V3 3/3] dt-bindings: spi: Convert imx lpspi to json-schema
Date: Tue, 16 Jun 2020 12:26:15 +0800 [thread overview]
Message-ID: <1592281575-32708-4-git-send-email-Anson.Huang@nxp.com> (raw)
In-Reply-To: <1592281575-32708-1-git-send-email-Anson.Huang@nxp.com>
Convert the i.MX LPSPI binding to DT schema format using json-schema
Signed-off-by: Anson Huang <Anson.Huang@nxp.com>

Changes since V2:
- remove redundant "maxItems" in "clocks" and "clock-names".

-* Freescale Low Power SPI (LPSPI) for i.MX
-
-Required properties:
-- compatible :
- - "fsl,imx7ulp-spi" for LPSPI compatible with the one integrated on i.MX7ULP soc
- - "fsl,imx8qxp-spi" for LPSPI compatible with the one integrated on i.MX8QXP soc
-- reg : address and length of the lpspi master registers
-- interrupt-parent : core interrupt controller
-- interrupts : lpspi interrupt
-- clocks : lpspi clock specifier. Its number and order need to correspond to the
- value in clock-names.
-- clock-names : Corresponding to per clock and ipg clock in "clocks"
- respectively. In i.MX7ULP, it only has per clk, so use CLK_DUMMY
- to fill the "ipg" blank.
-- spi-slave : spi slave mode support. In slave mode, add this attribute without
- value. In master mode, remove it.
-
-Examples:
-
-lpspi2: lpspi@40290000 {
- compatible = "fsl,imx7ulp-spi";
- reg = <0x40290000 0x10000>;
- interrupt-parent = <&intc>;
- interrupts = <GIC_SPI 28 IRQ_TYPE_LEVEL_HIGH>;
- clocks = <&clks IMX7ULP_CLK_LPSPI2>,
- <&clks IMX7ULP_CLK_DUMMY>;
- clock-names = "per", "ipg";
- spi-slave;
-};
