Patch series adds support for enabling the PCIe controller and
UNIPHY found on Qualcomm IPQ5332 platform. PCIe0 is Gen3 X1 and
PCIe1 is Gen3 X2 are added.

This series combines [1] and [2]. [1] introduces IPQ5018 PCIe
support and [2] depends on [1] to introduce IPQ5332 PCIe support.
Since the community was interested in [2] (please see [3]), tried
to revive IPQ5332's PCIe support with v2 of this patch series.

v2 of this series pulled in the phy driver from [1] tried to
address comments/feedback given in both [1] and [2].

1. Enable IPQ5018 PCI support (Nitheesh Sekar) - https://lore.kernel.org/all/20231003120846.28626-1-quic_nsekar@quicinc.com/
2. Add PCIe support for Qualcomm IPQ5332 (Praveenkumar I) - https://lore.kernel.org/linux-arm-msm/20231214062847.2215542-1-quic_ipkumar@quicinc.com/
3. Community interest - https://lore.kernel.org/linux-arm-msm/20240310132915.GE3390@thinkpad/

v7: phy bindings:
    * Include data type definition to 'num-lanes'

    controller bindings:
    * Split the ipq9574 and ipq5332 changes into separate patches

    dtsi:
    * Add root port definitions

v6: phy bindings:
    * Fix num-lanes definition

    phy driver:
    * Fix num-lanes handling in probe to use generally followed pattern

    controller bindings:
    * Give more info in commit log

    dtsi:
    * Add assigned-clocks & assigned-clock-rates to controller nodes
    * Add num-lanes to pcie0_phy

v5: phy bindings:
    * Drop '3x1' & '3x2' from compatible string
    * Use 'num-lanes' to differentiate instead of '3x1' or '3x2'
      in compatible string
    * Describe clocks and resets instead of just maxItems

    phy driver:
    * Get num-lanes from DTS
    * Drop compatible specific init data as there is only one
      compatible string

    controller bindings:
    * Re-arrange 5332 and 9574 compatibles to handle fallback usage in dts

    dtsi:
    * Add 'num-lanes' to "pcie1_phy: phy@4b1000"
    * Make ipq5332 as main and ipq9574 as fallback compatible
    * Sort controller nodes per address

    misc:
    Add R-B tag from Konrad to dts and dtsi patches

v4: * phy bindings - Create ipq5332 compatible instead of reusing ipq9574 for bindings
    * phy bindings - Remove reset-names as the resets are handled with bulk APIs
    * phy bindings - Fix order in the 'required' section
    * phy bindings - Remove clock-output-names
    * dtsi - Add missing reset for pcie1_phy
    * dtsi - Convert 'reg-names' to a vertical list
    * dts - Fix nodes sort order
    * dts - Use property-n followed by property-names

v3: * Update the cover letter with the sources of the patches
    * Rename the dt-bindings yaml file similar to other phys
    * Drop ipq5332 specific pcie controllor bindings and reuse
      ipq9574 pcie controller bindings for ipq5332
    * Please see patches for specific changes
    * Set GPL license for phy-qcom-uniphy-pcie-28lp.c

v2: Address review comments from V1
    Drop the 'required clocks' change that would break ABI (in dt-binding, dts, gcc-ipq5332.c)
    Include phy driver from the dependent series

v1: https://lore.kernel.org/linux-arm-msm/20231214062847.2215542-1-quic_ipkumar@quicinc.com/
