Subject: [PATCH v2 0/3] usb: dwc3: Host wake up support from system suspend
Date: Thu,  9 Jul 2020 00:40:14 +0530	[thread overview]
Message-ID: <1594235417-23066-1-git-send-email-sanm@codeaurora.org> (raw)

Avoiding phy powerdown in host mode so that it can be wake up by devices.
Set GENPD_FLAG_ACTIVE_WAKEUP flag to keep usb30_prim gdsc active
when wakeup capable devices are connected to the host.
Using PDC interrupts instead of GIC interrupst to support wakeup in
xo shutdown case.

Changes in v2:
Dropped the patch in clock to set GENPD_FLAG_ACTIVE_WAKEUP flag and 
setting in usb dwc3 driver.
Separated the core patch and glue driver patch.
Made need_phy_for_wakeup flag part of dwc structure and 
hs_phy_flags as unsgined int.
Adrressed the comment on device_init_wakeup call.
Corrected offset for reading portsc register.
Added pacth to support wakeup in xo shutdown case.
