	 * Errata: USBHOST Configured In Smart-Idle Can Lead To a Deadlock

	 * id: i660

	 *

	 * Description:

	 * In the following configuration :

	 * - USBHOST module is set to smart-idle mode

	 * - PRCM asserts idle_req to the USBHOST module ( This typically

	 *   happens when the system is going to a low power mode : all ports

	 *   have been suspended, the master part of the USBHOST module has

	 *   entered the standby state, and SW has cut the functional clocks)

	 * - an USBHOST interrupt occurs before the module is able to answer

	 *   idle_ack, typically a remote wakeup IRQ.

	 * Then the USB HOST module will enter a deadlock situation where it

	 * is no more accessible nor functional.

	 *

	 * Workaround:

	 * Don't use smart idle; use only force idle, hence HWMOD_SWSUP_SIDLE

	 */

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

	 * Id: i571

	 *

	 * 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
