Subject: [PATCH v3 0/5] USB DWC3 host wake up support from system suspend
Date: Tue, 29 Sep 2020 16:17:27 +0530 [thread overview]
Message-ID: <1601376452-31839-1-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 v3:
Removed need_phy_for_wakeup flag and by default avoiding phy powerdown.
Addressed Matthias comments and added entry for DEV_SUPERSPEED.
Added suspend_quirk in dwc3 host and moved the dwc3_set_phy_speed_flags.
Added wakeup-source dt entry and reading in dwc-qcom.c glue driver.
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.
