yes it is coustomised board and ISP1161A host controller is connected to a
fpga device which is on the PCI bus. Infact it is one of the general purpose
io (gpio-23) to which usb interrupt line is connected and gpio is programmed
as an interrupt. I am getting the 'sof' interrupt continuously (at every
1msec) and I can see the corresponding interrupt count in /proc/interrupts
is incrementing accordingly.
Regarding hc 1161a, I have been told by phillips factory people that the
driver is working fine with the x86 platform. I did a port to the powerpc
platform.
