Subject: [PATCH v10 0/6] USB DWC3 host wake up support from system suspend
Date: Mon, 17 Jan 2022 11:14:02 +0530 [thread overview]
Message-ID: <1642398248-21753-1-git-send-email-quic_c_sanm@quicinc.com> (raw)
Avoiding phy powerdown in host mode when wakeup capable devices are
connected, so that it can be wake up by devices.
Set GENPD_FLAG_ALWAYS_ON flag to keep usb30_prim gdsc active to retain
controller status during suspend/resume.
Changes in v10:
PATCH 1/6: Change device_set_wakeup_capable to device_set_wakeup_enable
PATCH 2/6: Remove redundant else part in dwc3_resume_common
PATCH 4/6: Change the irg flags
PATCH 5/6: Set flag GENPD_FLAG_ALWAYS_ON
PATCH 6/6: Remove remove disable interrupts function and enable
interrupts in probe.
Changes in v9:
Checking with device_may_makeup property instead of phy_power_off flag.
Changed the IRQ flags and removed hs_phy_mode variable.
Changes in v8:
Moved the dwc3 suspend quirk code in dwc3/host.c to xhci-plat.c
Checking phy_power_off flag instead of usb_wakeup_enabled_descendants
to keep gdsc active.
Changes in v7:
Change in commit text and message in PATCH 1/5 and PATCH 5/5
as per Matthias suggestion.
Added curly braces for if and else if sections in PATCH 4/5.
Changes in v6:
Addressed comments in host.c and core.c
Separated the patches in dwc3-qcom.c to make it simple.
Dropped wakeup-source change as it is not related to this series.
Changes in v5:
Added phy_power_off flag to check presence of wakeup capable devices.
Dropped patch[v4,4/5] as it is present linux-next.
Addressed comments in host.c and dwc3-qcom.c.
Changes in v4:
Addressed Matthias comments raised in v3.
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.
