MLK-13125 usb: phy: phy-mxs-usb: enable weak 1p1 regulator for imx6ul during suspend For imx6ul PHY, when the system enters suspend, its 1p1 is off by default, that may cause the PHY get inaccurate USB DP/DM value. If the USB wakeup is enabled at this time, the unexpected wakeup may occur when the system enters suspend. In this patch, when the vbus is there, we enable weak 1p1 during the PHY suspend API, in that case, the USB DP/DM will be accurate for USB PHY, then unexpected usb wakeup will not be occurred, especially for the USB charger is connected scenario. The user needs to enable PHY wakeup for USB wakeup function using below setting. echo enabled > /sys/devices/platform/soc/2000000.aips-bus/20c9000.usbphy /power/wakeup Cc: Shaojun Wang <shaojun.wang@nxp.com> Cc: Anson Huang <anson.huang@nxp.com> Signed-off-by: Peter Chen <peter.chen@nxp.com>
