When dwc2 is configured as dual role (OTG), the USB gadget descriptors (device mode) are configured via configfs. This lead in calling usb_otg_descriptor_init(). In usb_otg_descriptor_init() (drivers/usb/gadget/config.c): - If otg caps structure is provided -> use it - If otg caps structure isn't provided -> HNP and SRP are enabled by default This could lead to a configuration mismatch beetween: - OTG controller: HNP and SRP aren't enabled - gadget descriptors: HNP and SRP are advertised Fabrice Gasnier (3): usb: dwc2: add otg_rev and otg_caps information for gadget driver usb: dwc2: stm32mp15: set otg_rev ARM: dts: stm32: set otg-rev on stm32mp151 arch/arm/boot/dts/stm32mp151.dtsi | 1 + drivers/usb/dwc2/core.h | 7 +++++++ drivers/usb/dwc2/gadget.c | 1 + drivers/usb/dwc2/params.c | 16 ++++++++++++++++ 4 files changed, 25 insertions(+)
