| |
Avoiding phy powerdown in host mode when wakeup capable devices are connected, 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.
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.
