Subject: [PATCH v4 09/12] dt-bindings: PCI: qcom: Add SM8550 compatible
Add the SM8550 platform to the binding.
Signed-off-by: Abel Vesa <abel.vesa@...aro.org>

The v3 of this patchset is:
https://lore.kernel.org/all/20230119112453.3393911-1-abel.vesa@linaro.org/
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
