Add device tree bindings for the video clock controller on Qualcomm SM8450 platform. Signed-off-by: Taniya Das <quic_tdas@xxxxxxxxxxx> Reviewed-by: Rob Herring <robh@xxxxxxxxxx> --- Changes since V2: - As per Stephen's comments drop clock-names to match how newer qcom clk bindings are being done. - Change the header file name as qcom,sm8450-videocc.h to match latest upstream header files. Changes since V1: - Change the properties order to keep reg after the compatible property. .../bindings/clock/qcom,sm8450-videocc.yaml | 77 +++++++++++++++++++ .../dt-bindings/clock/qcom,sm8450-videocc.h | 38 +++++++++ 2 files changed, 115 insertions(+) create mode 100644 Documentation/devicetree/bindings/clock/qcom,sm8450-videocc.yaml create mode 100644 include/dt-bindings/clock/qcom,sm8450-videocc.h diff --git a/Documentation/devicetree/bindings/clock/qcom,sm8450-videocc.yaml b/Documentation/devicetree/bindings/clock/qcom,sm8450-videocc.yaml new file mode 100644 index 000000000000..58e59065bb2a --- /dev/null +++ b/Documentation/devicetree/bindings/clock/qcom,sm8450-videocc.yaml @@ -0,0 +1,77 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/clock/qcom,sm8450-videocc.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Qualcomm Video Clock & Reset Controller on SM8450 + +maintainers: + - Taniya Das <quic_tdas@xxxxxxxxxxx> + +description: | + Qualcomm video clock control module provides the clocks, resets and power + domains on SM8450. + + See also:: include/dt-bindings/clock/qcom,videocc-sm8450.h + +properties: + compatible: + const: qcom,sm8450-videocc + + reg: + maxItems: 1 + + clocks: + items: + - description: Video AHB clock from GCC + - description: Board XO source + + power-domains: + maxItems: 1 + description: + MMCX power domain. + + required-opps: + maxItems: 1 + description: + A phandle to an OPP node describing required MMCX performance point. + + '#clock-cells': + const: 1 + + '#reset-cells': + const: 1 + + '#power-domain-cells': + const: 1 + +required: + - compatible + - reg + - clocks + - power-domains + - required-opps + - '#clock-cells' + - '#reset-cells' + - '#power-domain-cells' + +additionalProperties: false + +examples: + - | + #include <dt-bindings/clock/qcom,gcc-sm8450.h> + #include <dt-bindings/clock/qcom,rpmh.h> + #include <dt-bindings/power/qcom-rpmpd.h> + videocc: clock-controller@aaf0000 { + compatible = "qcom,sm8450-videocc"; + reg = <0x0aaf0000 0x10000>; + clocks = <&gcc GCC_VIDEO_AHB_CLK>, + <&rpmhcc RPMH_CXO_CLK>; + power-domains = <&rpmhpd SM8450_MMCX>; + required-opps = <&rpmhpd_opp_low_svs>; + #clock-cells = <1>; + #reset-cells = <1>; + #power-domain-cells = <1>; + }; +... diff --git a/include/dt-bindings/clock/qcom,sm8450-videocc.h b/include/dt-bindings/clock/qcom,sm8450-videocc.h new file mode 100644 index 000000000000..9d795adfe4eb --- /dev/null +++ b/include/dt-bindings/clock/qcom,sm8450-videocc.h @@ -0,0 +1,38 @@ +/* SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) */ +/* + * Copyright (c) 2023, Qualcomm Innovation Center, Inc.
