Therefore this patch creates a new binding file for this functional block. Signed-off-by: Markus Schneider-Pargmann Reviewed-by: Rob Herring --- Notes: Changes v3 -> v4: - Fixed clock names in the example as the clock patch series is merged into next now - Add missing ports decleration to the example Changes v1 -> v2: - Move the devicetree binding from mediatek,dpi into its own binding file. .../display/mediatek/mediatek,dpintf.yaml | 86 +++++++++++++++++++ 1 file changed, 86 insertions(+) create mode 100644 Documentation/devicetree/bindings/display/mediatek/mediatek,dpintf.yaml diff --git a/Documentation/devicetree/bindings/display/mediatek/mediatek,dpintf.yaml b/Documentation/devicetree/bindings/display/mediatek/mediatek,dpintf.yaml new file mode 100644 index 000000000000..3b5e0c148c97 --- /dev/null +++ b/Documentation/devicetree/bindings/display/mediatek/mediatek,dpintf.yaml @@ -0,0 +1,86 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/display/mediatek/mediatek,dpintf.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Mediatek DP_INTF Controller Device Tree Bindings + +maintainers: + - CK Hu + - Jitao shi + +description: | + The Mediatek DP_INTF function block is a sink of the display subsystem + connected to the display port controller. + +properties: + compatible: + enum: + - mediatek,mt8195-dpintf + + reg: + maxItems: 1 + + interrupts: + maxItems: 1 + + clocks: + items: + - description: hf_fmm Clock + - description: hf_fdp Clock + - description: Pixel Clock + - description: DP_INTF PLL + + clock-names: + items: + - const: hf_fmm + - const: hf_fdp + - const: pixel + - const: pll + + port: + $ref: /schemas/graph.yaml#/properties/port + description: + Output port node.
