This adds device tree bindings for the Sony ACX424AKP panel. Let's use YAML. Cc: devicetree@xxxxxxxxxxxxxxx Signed-off-by: Linus Walleij <linus.walleij@xxxxxxxxxx> --- ChangeLog v5->v6: - Fix the binding by simply not referencing the display controller bindings from a panel binding. ChangeLog v4->v5: - Fix up all warnings etc incurred from the now working schema check and DTS compilation. - I still have a vert annoying error message in the Sony panel bindings that uses this schema: sony,acx424akp.example.dt.yaml: panel@0: $nodename:0: 'panel@0' does not match '^dsi-controller(@.*)?$' As this is modeled very closely to Documentation/devicetree/bindings/net/mdio.yaml and that one doesn't emit this type of warning for its ethernet-phy@0 etc I am pretty much clueless and just can't see what the problem is. - If I can't figure this out the only viable next step is to drop the ambition to create yaml bindings simply because I'm unable to do it, and go back to traditional text bindings :( ChangeLog v3->v4: - Adjust to adjusted DSI bindings. ChangeLog v2->v3: - Put the example inside a dsi-controller so we have a complete example that verifies to the DSI panel generic binding. ChangeLog v1->v2: - Suggest a stand-alone YAML bindings file for DSI panels in a separate patch, and use that to reference the boolean "enforce-video-mode" attribute for DSI panels --- .../display/panel/sony,acx424akp.yaml | 49 +++++++++++++++++++ 1 file changed, 49 insertions(+) create mode 100644 Documentation/devicetree/bindings/display/panel/sony,acx424akp.yaml diff --git a/Documentation/devicetree/bindings/display/panel/sony,acx424akp.yaml b/Documentation/devicetree/bindings/display/panel/sony,acx424akp.yaml new file mode 100644 index 000000000000..185dcc8fd1f9 --- /dev/null +++ b/Documentation/devicetree/bindings/display/panel/sony,acx424akp.yaml @@ -0,0 +1,49 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/display/panel/sony,acx424akp.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Sony ACX424AKP 4" 480x864 AMOLED panel + +maintainers: + - Linus Walleij <linus.walleij@xxxxxxxxxx> + +allOf: + - $ref: panel-common.yaml# + +properties: + compatible: + const: sony,acx424akp + reg: true + reset-gpios: true + vddi-supply: + description: regulator that supplies the vddi voltage + enforce-video-mode: true + +required: + - compatible + - reg + - reset-gpios + +additionalProperties: false + +examples: + - | + #include <dt-bindings/gpio/gpio.h> + + dsi-controller@a0351000 { + compatible = "ste,mcde-dsi"; + reg = <0xa0351000 0x1000>; + #address-cells = <1>; + #size-cells = <0>; + + panel@0 { + compatible = "sony,acx424akp"; + reg = <0>; + vddi-supply = <&foo>; + reset-gpios = <&foo_gpio 0 GPIO_ACTIVE_LOW>; + }; + }; + +... -- 2.21.0
