Subject: [PATCH v2 0/2] PCI: qcom: Skip wait for link up if global IRQ handler is present
Date: Fri, 20 Sep 2024 15:47:58 +0530 [thread overview]
Message-ID: <20240920-remove_wait-v2-0-7c0fcb3b581d@quicinc.com> (raw)
In scenarios where a global IRQ handler is available to manage link up
interrupts, it may not be necessary to wait for the link to be up
during PCI initialization. This change helps in reducing the overall
bootup time.
As part of the PCIe link up event, the ICC and OPP values are updated.
