The v1 was here:
https://lore.kernel.org/all/20221116123505.2760397-1-abel.vesa@xxxxxxxxxx/

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
