Subject: [PATCH v2 2/2] usb: dwc2: stm32mp15: set otg_rev
Date: Fri, 8 Oct 2021 09:53:09 +0200	[thread overview]
Message-ID: <1633679589-16021-3-git-send-email-fabrice.gasnier@foss.st.com> (raw)
In-Reply-To: <1633679589-16021-1-git-send-email-fabrice.gasnier@foss.st.com>

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
