Signed-off-by: Abel Vesa <abel.vesa@xxxxxxxxxx> Reviewed-by: Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxx> --- This patchset relies on the following patchset: https://lore.kernel.org/all/20230117224148.1914627-1-abel.vesa@xxxxxxxxxx/ The v5 of this patch is: https://lore.kernel.org/all/20230124124714.3087948-10-abel.vesa@xxxxxxxxxx/ Changes since v5: * added Krzysztof's R-b tag Changes since v4: * dropped _serdes infix from ln_shrd table name and from every ln_shrd variable name * added hyphen between "no CSR" in both places * dropped has_ln_shrd_serdes_tbl * reordered qmp_pcie_offsets_v6_20 by struct members * added rollback for no-CSR reset in qmp_pcie_init fail path * moved ln_shrd offset calculation after port_b * dropped the minItems for interconnects * made iommu related properties global * renamed noc_aggr_4 back to noc_aggr Changes since v3: * renamed noc_aggr to noc_aggr_4, as found in the driver Changes since v2: * dropped the pipe from clock-names * removed the pcie instance number from aggre clock-names comment * renamed aggre clock-names to noc_aggr * dropped the _pcie infix from cnoc_pcie_sf_axi * renamed pcie_1_link_down_reset to simply link_down * added enable-gpios back, since pcie1 node will use it Changes since v1: * Switched to single compatible for both PCIes (qcom,pcie-sm8550) * dropped enable-gpios property * dropped interconnects related properties, the power-domains * properties and resets related properties the sm8550 specific allOf:if:then * dropped pipe_mux, phy_pipe and ref clocks from the sm8550 specific allOf:if:then clock-names array and decreased the minItems and maxItems for clocks property accordingly * added "minItems: 1" to interconnects, since sm8550 pcie uses just one, same for interconnect-names .../devicetree/bindings/pci/qcom,pcie.yaml | 44 +++++++++++++++++++ 1 file changed, 44 insertions(+) diff --git a/Documentation/devicetree/bindings/pci/qcom,pcie.yaml b/Documentation/devicetree/bindings/pci/qcom,pcie.yaml index 872817d6d2bd..9f1bdbc4b0fd 100644 --- a/Documentation/devicetree/bindings/pci/qcom,pcie.yaml +++ b/Documentation/devicetree/bindings/pci/qcom,pcie.yaml @@ -38,6 +38,7 @@ properties: - qcom,pcie-sm8350 - qcom,pcie-sm8450-pcie0 - qcom,pcie-sm8450-pcie1 + - qcom,pcie-sm8550 - items: - const: qcom,pcie-msm8996 - const: qcom,pcie-msm8998 @@ -58,6 +59,12 @@ properties: minItems: 1 maxItems: 8 + iommus: + maxItems: 1 + + iommu-map: + maxItems: 2 + # Common definitions for clocks, clock-names and reset. # Platform constraints are described later. clocks: @@ -108,6 +115,10 @@ properties: power-domains: maxItems: 1 + enable-gpios: + description: GPIO controlled connection to ENABLE# signal + maxItems: 1 + perst-gpios: description: GPIO controlled connection to PERST# signal maxItems: 1 @@ -205,6 +216,7 @@ allOf: - qcom,pcie-sm8350 - qcom,pcie-sm8450-pcie0 - qcom,pcie-sm8450-pcie1 + - qcom,pcie-sm8550 then: properties: reg: @@ -639,6 +651,37 @@ allOf: items: - const: pci # PCIe core reset + - if: + properties: + compatible: + contains: + enum: + - qcom,pcie-sm8550 + then: + properties: + clocks: + minItems: 7 + maxItems: 8 + clock-names: + minItems: 7 + items: + - const: aux # Auxiliary clock + - const: cfg # Configuration clock + - const: bus_master # Master AXI clock + - const: bus_slave # Slave AXI clock + - const: slave_q2a # Slave Q2A clock + - const: ddrss_sf_tbu # PCIe SF TBU clock + - const: noc_aggr # Aggre NoC PCIe AXI clock + - const: cnoc_sf_axi # Config NoC PCIe1 AXI clock + resets: + minItems: 1 + maxItems: 2 + reset-names: + minItems: 1 + items: + - const: pci # PCIe core reset + - const: link_down # PCIe link down reset + - if: properties: compatible: @@ -724,6 +767,7 @@ allOf: - qcom,pcie-sm8350 - qcom,pcie-sm8450-pcie0 - qcom,pcie-sm8450-pcie1 + - qcom,pcie-sm8550 then: oneOf: - properties: -- 2.34.1
