Sajid Dalvi bce9e7942a ANDROID: PCI/PM: Use usleep_range for d3hot_delay ... This patch implements a vendor hook that changes d3hot_delay to use usleep_range() instead of msleep() to reduce the resume time from 20ms to 10ms. The call sequence is as follows: pci_pm_resume_noirq() pci_pm_default_resume_early() pci_power_up() pci_raw_set_power_state() --> msleep(10) The default d3hot_delay is 10ms. Using msleep for delays less than 20ms could result in delays up to 20ms. Reference: Documentation/timers/timers-howto.rst Using usleep_range() results in the delay being closer to 10ms and this reduces the resume time.
