Subject: [PATCH 2/2] usb: chipidea: imx: add USB support for i.MX94
Date: Fri, 19 Sep 2025 15:11:11 +0800 [thread overview]
Message-ID: <20250919071111.2558628-2-xu.yang_2@nxp.com> (raw)
In-Reply-To: <20250919071111.2558628-1-xu.yang_2@nxp.com>
Add new imx94_usbmisc_ops for i.MX94 due to it has same wakeup logic
as i.MX95, but it doesn't need workaround for ERR051725, so pullup
is not needed.
