Summary: Linux crashes with SL811 and interrupt on PH2 on BF537

Details:

See https://blackfin.uclinux.org/gf/project/uclinux-dist/forum/?_forum_action=ForumMessageBrowse&thread_id=44236&action=ForumBrowse&forum_id=39. I have a custom BF537 board with an SL811 USB controller. I have the IRQ from the SL811 coming into the BF537 on PH2. The driver initializes correctly, but when I insert any device it causes Linux to crash. If I change the interrupt to PF4 there is no crash and the USB seems to work correctly.

I am using the RMII interface on Port H. RMII doesn't use PH2, but maybe this is contributing to the problem.

please post your actually config files you're using (use `make bugreport`). and

post your board config file.

If you use RMII PHY on BF537 and use PH2 in SL811, make sure you disconnect PH2

to your PHY on your board.

GPIO/IRQ support was added to trunk after this report for PH pins in RMII mode.

so this probably is a legit, but it's now fixed in trunk.
