Hello, > If the vendor drivers can detect the Link up event using mechanisms > such as Link up IRQ, then waiting for Link up during probe is not > needed. if the drivers can be notified when the link comes up, > vendor driver can enumerate downstream devices instead of waiting > here, which optimizes the boot time. > > So skip waiting for link to be up if the driver supports 'use_linkup_irq'. > > Currently, only Qcom RC driver supports the 'use_linkup_irq' as it can > detect the Link Up event using its own 'global IRQ' interrupt.
