Subject: [PATCH 2/3] usb: host: ehci-msm: Register ChipIdea UDC from glue wrapper
Date: Sat, 12 Apr 2025 19:40:03 +0000 [thread overview]
Message-ID: <20250412-msm8916-usb-v1-2-2925239caf4b@samcday.com> (raw)
In-Reply-To: <20250412-msm8916-usb-v1-0-2925239caf4b@samcday.com>
When CONFIG_DM_USB_GADGET is enabled, the CI UDC driver needs to be
explicitly bound. So we do this from the newly introduced glue driver.
