Add a device tree binding for the Solomon SSD1351, a 128x128 65k-color RGB OLED display controller driven over a 4-wire SPI bus. The binding builds on the shared solomon,ssd-common.yaml properties already used by the other Solomon display controllers.
Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Amit Barzilai <[email protected]> --- Changes since v1: - Drop solomon,width / solomon,height: both are deducible from the compatible and are already declared (as optional) by the referenced solomon,ssd-common.yaml, so a local override is unnecessary. - Drop the rotation property: it has no consumer (rotation is being removed from the driver). - Use dt-bindings/gpio/gpio.h flag defines in the example (reset-gpios active-low, dc-gpios active-high). .../bindings/display/solomon,ssd1351.yaml | 41 +++++++++++++++++++ 1 file changed, 41 insertions(+) create mode 100644 Documentation/devicetree/bindings/display/solomon,ssd1351.yaml diff --git a/Documentation/devicetree/bindings/display/solomon,ssd1351.yaml b/Documentation/devicetree/bindings/display/solomon,ssd1351.yaml new file mode 100644 index 000000000000..39622d74a41d --- /dev/null +++ b/Documentation/devicetree/bindings/display/solomon,ssd1351.yaml @@ -0,0 +1,41 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/display/solomon,ssd1351.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Solomon SSD1351 OLED Display Controller + +maintainers: + - Amit Barzilai <[email protected]> + +allOf: + - $ref: solomon,ssd-common.yaml# + +properties: + compatible: + enum: + - solomon,ssd1351 + +required: + - compatible + - reg + +unevaluatedProperties: false + +examples: + - | + #include <dt-bindings/gpio/gpio.h> + + spi { + #address-cells = <1>; + #size-cells = <0>; + + oled@0 { + compatible = "solomon,ssd1351"; + reg = <0x0>; + reset-gpios = <&gpio2 7 GPIO_ACTIVE_LOW>; + dc-gpios = <&gpio2 8 GPIO_ACTIVE_HIGH>; + spi-max-frequency = <10000000>; + }; + }; -- 2.54.0
