Subject: [PATCH] dt-bindings: ata: rcar-sata: Convert to json-schema
Date: Wed, 19 Feb 2020 16:41:46 +0100 [thread overview]
Message-ID: <20200219154146.11230-1-geert+renesas@glider.be> (raw)
Convert the Renesas R-Car Serial-ATA Device Tree binding documentation
to json-schema.
While at it:
- Remove the deprecated "renesas,rcar-sata" compatible value,
- Add "iommus", "power-domains", and "resets" properties,
- Update the example.
Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be>
---
Not having to care about the deprecated value simplifies the
jscon-schema.

-* Renesas R-Car SATA
-
-Required properties:
-- compatible : should contain one or more of the following:
- - "renesas,sata-r8a774b1" for RZ/G2N
- - "renesas,sata-r8a7779" for R-Car H1
- - "renesas,sata-r8a7790-es1" for R-Car H2 ES1
- - "renesas,sata-r8a7790" for R-Car H2 other than ES1
- - "renesas,sata-r8a7791" for R-Car M2-W
- - "renesas,sata-r8a7793" for R-Car M2-N
- - "renesas,sata-r8a7795" for R-Car H3
- - "renesas,sata-r8a77965" for R-Car M3-N
- - "renesas,rcar-gen2-sata" for a generic R-Car Gen2
- compatible device
- - "renesas,rcar-gen3-sata" for a generic R-Car Gen3 or
- RZ/G2 compatible device
- - "renesas,rcar-sata" is deprecated
-
- When compatible with the generic version nodes
- must list the SoC-specific version corresponding
- to the platform first followed by the generic
- version.
-
-- reg : address and length of the SATA registers;
-- interrupts : must consist of one interrupt specifier.
-- clocks : must contain a reference to the functional clock.
-
-Example:
-
-sata0: sata@ee300000 {
- compatible = "renesas,sata-r8a7791", "renesas,rcar-gen2-sata";
- reg = <0 0xee300000 0 0x2000>;
- interrupt-parent = <&gic>;
- interrupts = <0 105 IRQ_TYPE_LEVEL_HIGH>;
- clocks = <&mstp8_clks R8A7791_CLK_SATA0>;
-};
