PCI: qcom: Update ICC and OPP values after Link Up event
[ 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.
Fixes: 4581403f6792 ("PCI: qcom: Enumerate endpoints based on Link up event in 'global_irq' interrupt")
