Changes in V2: Provide details about sel-gpio Changes in V4: Provide details about max dp lanes Change the commit text Changes in V5: moved dp.txt to yaml file Changes in v6: - Squash all AUX LUT properties into one pattern Property - Make aux-cfg[0-9]-settings properties optional - Remove PLL/PHY bindings from DP controller dts - Add DP clocks description - Remove _clk suffix from clock names - Rename pixel clock to stream_pixel - Remove redundant bindings (GPIO, PHY, HDCP clock, etc..) - Fix indentation - Add Display Port as interface of DPU in DPU bindings and add port mapping accordingly. Chages in v7: - Add dp-controller.yaml file common between multiple SOC - Rename dp-sc7180.yaml to dp-controller-sc7180.yaml - change compatible string and add SOC name to it. - Remove Root clock generator for pixel clock - Add assigned-clocks and assigned-clock-parents bindings - Remove redundant properties, descriptions and blank lines - Add DP port in DPU bindings - Update depends-on tag in commit message and rebase change accordingly Changes in v8: - Add MDSS AHB clock in bindings This change depends-on: - https://patchwork.freedesktop.org/patch/366159/ Signed-off-by: Chandan Uddaraju Signed-off-by: Vara Reddy Signed-off-by: Tanmay Shah --- .../display/msm/dp-controller-sc7180.yaml | 144 ++++++++++++++++++ .../bindings/display/msm/dp-controller.yaml | 61 ++++++++ .../bindings/display/msm/dpu-sc7180.yaml | 11 ++ 3 files changed, 216 insertions(+) create mode 100644 Documentation/devicetree/bindings/display/msm/dp-controller-sc7180.yaml create mode 100644 Documentation/devicetree/bindings/display/msm/dp-controller.yaml diff --git a/Documentation/devicetree/bindings/display/msm/dp-controller-sc7180.yaml b/Documentation/devicetree/bindings/display/msm/dp-controller-sc7180.yaml new file mode 100644 index 000000000000..ce89ea73e778 --- /dev/null +++ b/Documentation/devicetree/bindings/display/msm/dp-controller-sc7180.yaml @@ -0,0 +1,144 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/display/msm/dp-controller-sc7180.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: MSM SC7180 Display Port Controller. + +maintainers: + - Chandan Uddaraju + - Vara Reddy + - Tanmay Shah + +description: | + Device tree bindings for DP host controller for MSM SC7180 target + that are compatible with VESA Display Port interface specification. + +allOf: + - $ref: dp-controller.yaml# + +properties: + compatible: + items: + - enum: + - qcom,sc7180-dp + + reg: + maxItems: 1 + reg-names: + const: dp_controller + + interrupts: + maxItems: 1 + + clocks: + maxItems: 5 + + clock-names: + items: + - const: core_iface + - const: core_aux + - const: ctrl_link + - const: ctrl_link_iface + - const: stream_pixel + + "#clock-cells": + const: 1 + + assigned-clocks: + maxItems: 1 + assigned-clock-parents: + maxItems: 1 + + data-lanes: + $ref: "/schemas/types.yaml#/definitions/uint32-array" + minItems: 1 + maxItems: 4 + + vdda-1p2-supply: + description: phandle to vdda 1.2V regulator node. + + vdda-0p9-supply: + description: phandle to vdda 0.9V regulator node. + + ports: + type: object + properties: + "#address-cells": + const: 1 + + "#size-cells": + const: 0 + + port@0: + type: object + port@1: + type: object + +required: + - compatible + - reg + - reg-names + - interrupts + - clocks + - clock-names + - assigned-clocks + - assigned-clock-parents + - vdda-1p2-supply + - vdda-0p9-supply + - data-lanes + - ports + +additionalProperties: false + +examples: + - | + #include + #include + #include + msm_dp: displayport-controller@ae90000{ + compatible = "qcom,sc7180-dp";
