Nord has a single Gen5-capable QMP PCIe PHY block split into four independently-clocked and independently-resettable ports (A/B/C/D). Firmware selects the active lane topology at boot via a TCSR configuration register, and the same PHY block can appear as a single x16 port, x8+x8, x8+x4+x4, or x8+x4+x2+x2 depending on that mode. This is similar in spirit to the Glymur multi-PHY support already posted, except Nord's PHY registers are programmed by Linux rather than by firmware, so this series adds the PLL, TXRXZ, PCS and PCS-lane init tables along with the power-up/power-down/soft-reset sequencing needed to bring each port up. The series also documents and wires up the qcom,nord-pcie compatible (reusing the existing SA8775P PCIe controller binding), and adds a CORE_CLK_CGC_DIS/AUX_PWR_DET workaround required to avoid a timing convergence issue in the PCIe power domain.
