Signed-off-by: Yuji Ishikawa Reviewed-by: Nobuhiro Iwamatsu Reviewed-by: Krzysztof Kozlowski --- Changelog v2: - no change Changelog v3: - no change Changelog v4: - fix style problems at the v3 patch - remove "index" member - update example Changelog v5: - no change Changelog v6: - add register definition of BUS-IF and MPU Changelog v7: - remove trailing "bindings" from commit header message - remove trailing "Device Tree Bindings" from title - fix text wrapping of description - change compatible to visconti5-viif - explicitly define allowed properties for port::endpoint Changelog v8: - Suggestion from Krzysztof Kozlowski - rename bindings description file - use block style array instead of inline style - remove clock-lane (as it is fixed at position 0) - update sample node's name - use lowercase hex for literals - Suggestion from Laurent Pinchart - update description message port::description - remove port::endpoint::bus-type as it is fixed to <4> - remove port::endpoint::clock-lanes from example - add port::endpoint::data-lanes to required parameters list - fix sequence of data-lanes: <1 2 3 4> because current driver does not support data reordering - update port::endpoint::data-lanes::description - remove redundant type definition for port::endpoint::data-lanes Changelog v9: - place "required" after "properties" - dictionary ordering of properties .../media/toshiba,visconti5-viif.yaml | 105 ++++++++++++++++++ 1 file changed, 105 insertions(+) create mode 100644 Documentation/devicetree/bindings/media/toshiba,visconti5-viif.yaml diff --git a/Documentation/devicetree/bindings/media/toshiba,visconti5-viif.yaml b/Documentation/devicetree/bindings/media/toshiba,visconti5-viif.yaml new file mode 100644 index 000000000000..97e8bda427f3 --- /dev/null +++ b/Documentation/devicetree/bindings/media/toshiba,visconti5-viif.yaml @@ -0,0 +1,105 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/media/toshiba,visconti5-viif.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Toshiba Visconti5 SoC Video Input Interface + +maintainers: + - Nobuhiro Iwamatsu + +description: |- + Toshiba Visconti5 SoC Video Input Interface (VIIF) receives MIPI CSI2 video + stream, processes the stream with image signal processors (L1ISP, L2ISP), + then stores pictures to main memory. + +properties: + compatible: + const: toshiba,visconti5-viif + + reg: + items: + - description: Registers for capture control + - description: Registers for CSI2 receiver control + - description: Registers for bus interface unit control + - description: Registers for Memory Protection Unit + + interrupts: + items: + - description: Sync Interrupt + - description: Status (Error) Interrupt + - description: CSI2 Receiver Interrupt + - description: L1ISP Interrupt + + port: + $ref: /schemas/graph.yaml#/$defs/port-base + unevaluatedProperties: false + description: CSI-2 input port, with a single endpoint connected to the CSI-2 transmitter. + + properties: + endpoint: + $ref: video-interfaces.yaml# + additionalProperties: false + + properties: + data-lanes: + description: VIIF supports 1, 2, 3 or 4 data lanes + minItems: 1 + items: + - const: 1 + - const: 2 + - const: 3 + - const: 4 + + clock-noncontinuous: true + link-frequencies: true + remote-endpoint: true + + required: + - clock-noncontinuous + - data-lanes + - link-frequencies + - remote-endpoint + +required: + - compatible + - reg + - interrupts + - port + +additionalProperties: false + +examples: + - | + #include + #include + + soc { + #address-cells = <2>; + #size-cells = <2>; + + video@1c000000 { + compatible = "toshiba,visconti5-viif"; + reg = <0 0x1c000000 0 0x6000>, + <0 0x1c008000 0 0x400>, + <0 0x1c00e000 0 0x1000>, + <0 0x2417a000 0 0x1000>; + interrupts = , + , + , + ; + + port { + #address-cells = <1>; + #size-cells = <0>; + + csi_in0: endpoint { + clock-noncontinuous; + data-lanes = <1 2>; + link-frequencies = /bits/ 64 <456000000>; + remote-endpoint = <&imx219_out0>; + }; + }; + }; + };
