+Subject: [PATCH] [PATCH][PATCH 1/1] usb: add embedded Host feature support
+
+add EH(Embedded Host) feature for PET authentication
+1. need CONFIG_USB_OTG_WHITELIST enable
+   CONFIG_USB_OTG_WHITELIST=y
+
+2. host device tree node need include "tpl-support" keyword
+   &xhci {
+	   tpl-support;
+   }
