 	 * Errata: USB host EHCI may stall when entering smart-standby mode

 	 *
+	 * Description:
+	 * When the USBHOST module is set to smart-standby mode, and when it is
+	 * ready to enter the standby state (i.e. all ports are suspended and
+	 * all attached devices are in suspend mode), then it can wrongly assert
+	 * the Mstandby signal too early while there are still some residual OCP
+	 * transactions ongoing. If this condition occurs, the internal state
+	 * machine may go to an undefined state and the USB link may be stuck
+	 * upon the next resume.
+	 *
+	 * Workaround:
+	 * Don't use smart standby; use only force standby,
+	 * hence HWMOD_SWSUP_MSTANDBY
+	 */
