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

|
|
|
+ * 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
