It was listed with sm8150 block which has different set of clocks than used in sc81880x, so this needs to have its own block of clocks and resets > > > > Signed-off-by: Vinod Koul <vkoul@kernel.org> > > --- > > .../devicetree/bindings/pci/qcom,pcie.yaml | 29 ++++++++++++++++++- > > 1 file changed, 28 insertions(+), 1 deletion(-) > > > > diff --git a/Documentation/devicetree/bindings/pci/qcom,pcie.yaml b/Documentation/devicetree/bindings/pci/qcom,pcie.yaml > > index 81971be4e554..40a1f451a3d3 100644 > > --- a/Documentation/devicetree/bindings/pci/qcom,pcie.yaml > > +++ b/Documentation/devicetree/bindings/pci/qcom,pcie.yaml > > @@ -476,6 +476,33 @@ allOf: > > items: > > - const: pci # PCIe core reset > > > > + - if: > > + properties: > > + compatible: > > + contains: > > + enum: > > + - qcom,pcie-sc8180x > > + then: > > + properties: > > + clocks: > > + minItems: 8 > > + maxItems: 8 > > + clock-names: > > + items: > > + - const: pipe # PIPE clock > > + - 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: ref # REFERENCE clock > > + - const: tbu # PCIe TBU clock > > + resets: > > + maxItems: 1 > > + reset-names: > > + items: > > + - const: pci # PCIe core reset > > + > > - if: > > properties: > > compatible: > > @@ -524,7 +551,6 @@ allOf: > > compatible: > > contains: > > enum: > > - - qcom,pcie-sc8180x > > - qcom,pcie-sm8150 > > - qcom,pcie-sm8250 > > then: > > @@ -749,6 +775,7 @@ allOf: > > contains: > > enum: > > - qcom,pcie-sa8540p > > + - qcom,pcie-sc8180x > > - qcom,pcie-sc8280xp > > then: > > required: > > Best regards, > Krzysztof
