Base DT: https://lore.kernel.org/all/20241122023314.1616353-1-quic_ziyuzhan@xxxxxxxxxxx/ This series add PCIe current load vote/devote for PCIe PHY driver, add vdda-pll-max-microamp property in DT, and also document current load properties in dt-bindings. On platform QCS615, the current that phy consumes will exceed the maximum current the regulator can provide in LPM mode, leading to over current protection and system boot up stuck. This series can fix the issue by setting current load to an expected value parsed from DT. This will vote the regulator to work in HPM mode so that it is able to output a larger current and viod over current protection. When the PCIe PHY poweroff in case like system suspend or shutdown, it will also devote regulator back to LPM mode to decline regulator itself's power consumption by setting load to zero. Besides, three optional current load properties are added in dt-bindings, vdda-phy-max-microamp, vdda-pll-max-microamp and vdda-qref-max-microamp. PCIe PHY that wants to vote for more current consumption should provide corresponding property.
