Subject: [PATCH v6 0/6] pci: qcom: Add QCS8300 PCIe support
This series depend on the sa8775p gcc_aux_clock and link_down reset change
https://lore.kernel.org/all/20250529035416.4159963-1-quic_ziyuzhan@quicinc.com/
This series adds document, phy, configs support for PCIe in QCS8300.
It also adds 'link_down' reset for sa8775p.
Have follwing changes:
- Add dedicated schema for the PCIe controllers found on QCS8300.
- Add compatible for qcs8300 platform.
- Add configurations in devicetree for PCIe0, including registers, clocks, interrupts and phy setting sequence.
- Add configurations in devicetree for PCIe1, including registers, clocks, interrupts and phy setting sequence.
