If anyone has any objections, please let me know. ------------------ From: Krishna chaitanya chundru [ Upstream commit f0639013d340580b72df95d012a93f35eeb0da64 ] 4581403f6792 ("PCI: qcom: Enumerate endpoints based on Link up event in 'global_irq' interrupt") added the Link Up-based enumeration support, but did not update the ICC/OPP vote once link is up. Before that, the update happened during probe and the endpoints may or may not be enumerated at that time, so the ICC/OPP vote was not guaranteed to be accurate. With Link Up-based enumeration support, the driver can request the accurate vote based on the PCIe link. Call qcom_pcie_icc_opp_update() in qcom_pcie_global_irq_thread() after enumerating the endpoints.
