+* 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
