Subject: [PATCH v3 3/3] usb: phy: mxs: remove CONFIG_USB_OTG condition for mxs_phy_is_otg_host()
Date: Thu, 28 Dec 2023 19:07:53 +0800	[thread overview]
Message-ID: <20231228110753.1755756-3-xu.yang_2@nxp.com> (raw)
In-Reply-To: <20231228110753.1755756-1-xu.yang_2@nxp.com>

When CONFIG_USB_OTG is not set, mxs_phy_is_otg_host() will always return
false. This behaviour is wrong. Since phy.last_event will always be set
for either host or device mode. Therefore, CONFIG_USB_OTG condition
can be removed.
