The OHCI scheduling overrun interrupt is supported as described in the OHCI
Specification for USB.
The OHCI HCDONEHEAD writeback interrupt is supported as described in the
OHCI Specification for USB.
The OHCI start of frame interrupt is supported as described in the OHCI
Specification for USB.
The OHCI resume detect interrupt is supported as described in the OHCI
Specification for USB.
The OHCI unrecoverable error interrupt is supported as described in the OHCI
Specification for USB. This interrupt occurs if the USB host controller is unable
to complete an OCPI bus read or OCPI write within 4096 OCPI bus clocks
when the USB host OCPI bus time-out feature is enabled [see Table 15-28,
Host Time-out Control Register (HOSTTIMEOUTCTRL)]. When an OCPI bus
time-out causes an
HOSTUESTATUS are updated. When an isochronous TD is processed with
an OFFSET/PSW field that is not set for Not Accessed, an unrecoverable error
interrupt is generated, but HOSTUEADDR and HOSTUESTATUS are not
updated.
The OHCI frame number overflow interrupt is supported as described in the
OHCI Specification for USB.
The OHCI root hub status change interrupt is supported as described in the
OHCI Specification for USB. The OMAP5912 does not provide a connection
between the USB host controller and USB port overcurrent detection
hardware, so the root hub status change interrupt does not occur because of
a port overcurrent event.
The optional OHCI ownership change interrupt is not supported.
