Allow a child node for this regulator device in addition to SRAM child nodes. Signed-off-by: Samuel Holland <samuel@...lland.org> --- Changes in v4: - Remove unevaluatedProperties from regulators schema reference Changes in v3: - Require the regulators node to have a unit address - Reference the regulator schema from the SRAM controller schema - Move the system LDOs example to the SRAM controller schema - Reorder the patches so the example passes validation Changes in v2: - New patch for v2 .../allwinner,sun4i-a10-system-control.yaml | 28 +++++++++++++++++++ 1 file changed, 28 insertions(+) diff --git a/Documentation/devicetree/bindings/sram/allwinner,sun4i-a10-system-control.yaml b/Documentation/devicetree/bindings/sram/allwinner,sun4i-a10-system-control.yaml index 98a7dc7f467d..c487ac9521e9 100644 --- a/Documentation/devicetree/bindings/sram/allwinner,sun4i-a10-system-control.yaml +++ b/Documentation/devicetree/bindings/sram/allwinner,sun4i-a10-system-control.yaml @@ -56,6 +56,9 @@ properties: ranges: true patternProperties: + "^regulators@[0-9a-f]+$": + $ref: /schemas/regulator/allwinner,sun20i-d1-system-ldos.yaml# + "^sram@[a-z0-9]+": type: object @@ -130,3 +133,28 @@ examples: }; }; }; + + - | + syscon@...0000 { + compatible = "allwinner,sun20i-d1-system-control"; + reg = <0x3000000 0x1000>; + ranges; + #address-cells = <1>; + #size-cells = <1>; + + regulators@...0150 { + compatible = "allwinner,sun20i-d1-system-ldos"; + reg = <0x3000150 0x4>; + + reg_ldoa: ldoa { + regulator-min-microvolt = <1800000>; + regulator-max-microvolt = <1800000>; + }; + + reg_ldob: ldob { + regulator-name = "vcc-dram"; + regulator-min-microvolt = <1500000>; + regulator-max-microvolt = <1500000>; + }; + }; + }; -- 2.37.4
