Signed-off-by: Frank Wunderlich Reviewed-by: Krzysztof Kozlowski --- v4: - add reviewed-by - remove minitems for clock-names as i have static list to fix error - fix reg error by using 32-bit adressing in binding example - change lane-map to u32 data-lanes - tried to move data-lanes to phy-provider https://github.com/frank-w/dt-schema/blob/main/dtschema/schemas/phy/phy-provider.yaml#L17 cloned and installed via pip install -e verified with pip show, but phy-privider seems not to be applied v3: - drop quotes - drop rk3588 - make clockcount fixed to 3 - full path for binding header file - drop phy-mode and its header and add lane-map v2: dt-bindings: rename yaml for PCIe v3 rockchip-pcie3-phy.yaml => rockchip,pcie3-phy.yaml changes in pcie3 phy yaml - change clock names to ordered const list - extend pcie30-phymode description - add phy-cells to required properties - drop unevaluatedProperties - example with 1 clock each line - use default property instead of text describing it - update license --- .../bindings/phy/rockchip,pcie3-phy.yaml | 80 +++++++++++++++++++ 1 file changed, 80 insertions(+) create mode 100644 Documentation/devicetree/bindings/phy/rockchip,pcie3-phy.yaml diff --git a/Documentation/devicetree/bindings/phy/rockchip,pcie3-phy.yaml b/Documentation/devicetree/bindings/phy/rockchip,pcie3-phy.yaml new file mode 100644 index 000000000000..9f2d8d2cc7a5 --- /dev/null +++ b/Documentation/devicetree/bindings/phy/rockchip,pcie3-phy.yaml @@ -0,0 +1,80 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/phy/rockchip,pcie3-phy.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Rockchip PCIe v3 phy + +maintainers: + - Heiko Stuebner + +properties: + compatible: + enum: + - rockchip,rk3568-pcie3-phy + + reg: + maxItems: 1 + + clocks: + minItems: 3 + maxItems: 3 + + clock-names: + items: + - const: refclk_m + - const: refclk_n + - const: pclk + + data-lanes: + description: which lanes (by position) should be mapped to which + controller (value). 0 means lane disabled, higher value means used. + (controller-number +1 ) + $ref: /schemas/types.yaml#/definitions/uint32-array + minItems: 2 + maxItems: 16 + items: + minimum: 0 + maximum: 16 + + "#phy-cells": + const: 0 + + resets: + maxItems: 1 + + reset-names: + const: phy + + rockchip,phy-grf: + $ref: /schemas/types.yaml#/definitions/phandle + description: phandle to the syscon managing the phy "general register files" + + rockchip,pipe-grf: + $ref: /schemas/types.yaml#/definitions/phandle + description: phandle to the syscon managing the pipe "general register files" + +required: + - compatible + - reg + - rockchip,phy-grf + - "#phy-cells" + +additionalProperties: false + +examples: + - | + #include + pcie30phy: phy@fe8c0000 { + compatible = "rockchip,rk3568-pcie3-phy"; + reg = <0xfe8c0000 0x20000>; + #phy-cells = <0>; + clocks = <&pmucru CLK_PCIE30PHY_REF_M>, + <&pmucru CLK_PCIE30PHY_REF_N>, + <&cru PCLK_PCIE30PHY>; + clock-names = "refclk_m", "refclk_n", "pclk"; + resets = <&cru SRST_PCIE30PHY>; + reset-names = "phy"; + rockchip,phy-grf = <&pcie30_phy_grf>; + };
