There are some additions to the binding that were not in the original file. This binding is used in MT7621 and MT7628a Ralink SoCs. To properly match both dts nodes in tree we need to add to the schema 'clocks', 'clock-names' and 'reset-names'. Both 'clock-names' and 'reset-names' use 'spi' as string so maintain that as const in the schema. Reviewed-by: Krzysztof Kozlowski Signed-off-by: Sergio Paracuellos --- Changes in v3 resent: - Send this patch also to linux-spi and Mark B Changes in v3: - Add Krzysztof's Reviewed-by tag. Changes in v2: - Address review comment from Krzysztof: - Rebase onto last kernel version. - Drop address-cells and size-cells. - Explain deviations from the original file in commit message. - Drop reset-names as required property. .../bindings/spi/ralink,mt7621-spi.yaml | 61 +++++++++++++++++++ .../devicetree/bindings/spi/spi-mt7621.txt | 26 -------- 2 files changed, 61 insertions(+), 26 deletions(-) create mode 100644 Documentation/devicetree/bindings/spi/ralink,mt7621-spi.yaml delete mode 100644 Documentation/devicetree/bindings/spi/spi-mt7621.txt diff --git a/Documentation/devicetree/bindings/spi/ralink,mt7621-spi.yaml b/Documentation/devicetree/bindings/spi/ralink,mt7621-spi.yaml new file mode 100644 index 000000000000..22879f7dcb77 --- /dev/null +++ b/Documentation/devicetree/bindings/spi/ralink,mt7621-spi.yaml @@ -0,0 +1,61 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/spi/ralink,mt7621-spi.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +maintainers: + - Sergio Paracuellos + +title: Mediatek MT7621/MT7628 SPI controller + +allOf: + - $ref: /schemas/spi/spi-controller.yaml# + +properties: + compatible: + const: ralink,mt7621-spi + + reg: + maxItems: 1 + + clocks: + maxItems: 1 + + clock-names: + const: spi + + resets: + maxItems: 1 + + reset-names: + const: spi + +required: + - compatible + - reg + - resets + - "#address-cells" + - "#size-cells" + +unevaluatedProperties: false + +examples: + - | + #include + #include + + spi@b00 { + compatible = "ralink,mt7621-spi"; + reg = <0xb00 0x100>; + clocks = <&sysc MT7621_CLK_SPI>; + clock-names = "spi"; + resets = <&sysc MT7621_RST_SPI>; + reset-names = "spi"; + + #address-cells = <1>; + #size-cells = <0>; + + pinctrl-names = "default"; + pinctrl-0 = <&spi_pins>; + }; diff --git a/Documentation/devicetree/bindings/spi/spi-mt7621.txt b/Documentation/devicetree/bindings/spi/spi-mt7621.txt deleted file mode 100644 index d5baec0fa56e..000000000000 --- a/Documentation/devicetree/bindings/spi/spi-mt7621.txt +++ /dev/null @@ -1,26 +0,0 @@ -Binding for MTK SPI controller (MT7621 MIPS) - -Required properties: -- compatible: Should be one of the following: - - "ralink,mt7621-spi": for mt7621/mt7628/mt7688 platforms -- #address-cells: should be 1. -- #size-cells: should be 0. -- reg: Address and length of the register set for the device -- resets: phandle to the reset controller asserting this device in - reset - See ../reset/reset.txt for details. - -Optional properties: -- cs-gpios: see spi-bus.txt. - -Example: - -- SoC Specific Portion: -spi0: spi@b00 { - compatible = "ralink,mt7621-spi"; - reg = <0xb00 0x100>; - #address-cells = <1>; - #size-cells = <0>; - resets = <&rstctrl 18>; - reset-names = "spi"; -};
