This series tries to account for a delay from the IDDIG debounce filter when switching modes. This delay is a function of the PHY clock speed and can range from 5-50 ms. This delay must be taken into account on core reset and force modes. A full explanation is provided in the patch commit log and code comments. Patch 1 is a prerequisite to this fix. Patch 2 implements the delay for core reset. Patch 3 implements the delay for set/clear force modes. Appreciate any testing, especially on RK3188 and RPi platforms. Patch 1-2 can probably be merged right now as they shouldn't break anything. Patch 3 should solve RPi issues, but has problems in RK3188 that need to be debugged. v3: * Added tested-bys for patch 1-2 * Fixed an issue where a function was not returning a value * Dropped patch 4 v2: * Broke up the last patch of the original series Regards, John John Youn (3): usb: dwc2: gadget: Only initialize device if in device mode usb: dwc2: Add delay to core soft reset usb: dwc2: Properly account for the force mode delays drivers/usb/dwc2/core.c | 128 ++++++++++++++++++++++++++++++++++++++++------ drivers/usb/dwc2/core.h | 1 + drivers/usb/dwc2/gadget.c | 7 ++- drivers/usb/dwc2/hw.h | 1 + 4 files changed, 118 insertions(+), 19 deletions(-) -- 2.9.0 -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
