STM32MP15 complies with the OTG 2.0. Set OTG revision accordingly. It is useful for the of_usb_update_otg_caps() routine to check and update otg_rev to the lower value between DT and provided params. Signed-off-by: Fabrice Gasnier <fabrice.gasnier@foss.st.com> --- Changes in v2: - set otg_rev in otg_caps structure directly --- drivers/usb/dwc2/params.c | 2 ++ 1 file changed, 2 insertions(+)
