Changes in v11.1: - _Actually_ dropped the arm,inline property mode, having forgotten to do so in v11. Changes in v11: - Dropped in arm,inline_mode property. This is now identical to the reviewed version 8, so I have kept the tags on there. Changes in v10: - None Changes in v9: - Added the arm,inline_mode property to differentiate between inline and memory input configurations Changes in v8: - Added the video clock back in. Now that we have actual hardware it's clear that it's necessary. - Added reset lines - Dropped R-bs Changes in v7: - None Changes in v6: - None Changes in v5: - None Changes in v4: - Switched to port instead of ports Changes in v3: - Dropped the video clock as suggested by Laurent. I didn't retain it for the purposes of the refcount since this driver will call .s_stream() for the sensor driver which will refcount the clock anyway. - Clarified that the port is a parallel input port rather (Sakari) Changes in v2: - Added clocks information - Fixed the warnings raised by Rob --- .../bindings/media/arm,mali-c55.yaml | 82 +++++++++++++++++++ 1 file changed, 82 insertions(+) create mode 100644 Documentation/devicetree/bindings/media/arm,mali-c55.yaml diff --git a/Documentation/devicetree/bindings/media/arm,mali-c55.yaml b/Documentation/devicetree/bindings/media/arm,mali-c55.yaml new file mode 100644 index 000000000000..efc88fd2c447 --- /dev/null +++ b/Documentation/devicetree/bindings/media/arm,mali-c55.yaml @@ -0,0 +1,82 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/media/arm,mali-c55.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: ARM Mali-C55 Image Signal Processor + +maintainers: + - Daniel Scally + - Jacopo Mondi + +properties: + compatible: + const: arm,mali-c55 + + reg: + maxItems: 1 + + interrupts: + maxItems: 1 + + clocks: + items: + - description: ISP Video Clock + - description: ISP AXI clock + - description: ISP AHB-lite clock + + clock-names: + items: + - const: vclk + - const: aclk + - const: hclk + + resets: + items: + - description: vclk domain reset + - description: aclk domain reset + - description: hclk domain reset + + reset-names: + items: + - const: vresetn + - const: aresetn + - const: hresetn + + port: + $ref: /schemas/graph.yaml#/properties/port + description: Input parallel video bus + + properties: + endpoint: + $ref: /schemas/graph.yaml#/properties/endpoint + +required: + - compatible + - reg + - interrupts + - clocks + - clock-names + - port + +additionalProperties: false + +examples: + - | + mali_c55: isp@400000 { + compatible = "arm,mali-c55"; + reg = <0x400000 0x200000>; + clocks = <&clk 0>, <&clk 1>, <&clk 2>; + clock-names = "vclk", "aclk", "hclk"; + resets = <&resets 0>, <&resets 1>, <&resets 2>; + reset-names = "vresetn", "aresetn", "hresetn"; + interrupts = <0>; + + port { + isp_in: endpoint { + remote-endpoint = <&csi2_rx_out>; + }; + }; + }; +... -- 2.34.1
