[Prism54-devel] No interrupt after isl38xx_w32_flush(ISL38XX_DEV_INT_UPDATE...)?

[waveon]

Hi all,

I try to port the prism54 driver to MIPS platform ( in little endian mode ) ,
everything looks ok , but I can't get interrupt after I issue isl38xx_w32_flush(ISL38XX_DEV_INT_UPDATE) command.
I observe that the mini-PCI signal REQ# , GNT# , FRAME# , IRDY# are already asserted , but DEVSEL# and TRDY# are still in de-asserted state.

But if I try to trigger another interrupt such as ISL38XX_DEV_INT_SLEEP , I can get that interrupt immediately.
Is this DMA problem ?

I find there is someone encounter the same problem before ,but there is no response.
Please reference the following link.

Thanks for any help.

Kevin
