Subject: [PATCH 3/3] usb: chipidea: imx: add missing USB PHY DPDM wakeup setting
Date: Wed, 17 May 2023 16:19:07 +0800 [thread overview]
Message-ID: <20230517081907.3410465-3-xu.yang_2@nxp.com> (raw)
In-Reply-To: <20230517081907.3410465-1-xu.yang_2@nxp.com>
USB PHY DPDM wakeup bit is enabled by default, when USB wakeup
is not required(/sys/.../wakeup is disabled), this bit should be
disabled, otherwise we will have unexpected wakeup if do USB device
connect/disconnect while system sleep.
This bit can be enabled for both host and device mode.
