* 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
*/
/*
* During system boot; If the hwmod framework resets the module
* the module will have smart idle settings; which can lead to deadlock
* (above Errata Id:i660); so, dont reset the module during boot;
* Use HWMOD_INIT_NO_RESET.
