This series accounts for the 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. This revision of the series increases the IDDIG delay to 100 ms. Some rockchip platforms seem to timeout even with 50 ms so I have doubled this. Appreciate any testing on RK3188 and RPi platforms. v4: * Increased the IDDIG delay to 110ms. * Removed tested-by for patch 2 since I have changed the delays. 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 | 126 +++++++++++++++++++++++++++++++++++++++------- drivers/usb/dwc2/core.h | 1 + drivers/usb/dwc2/gadget.c | 7 ++- drivers/usb/dwc2/hw.h | 1 + 4 files changed, 116 insertions(+), 19 deletions(-) -- 2.9.0
