question: The function pxa_camera_dma_irq reset the passed FIFO channel if an

But it should clear the others FIFOs too? Or is this wrong?
From the datasheet:
"Reset input FIFO (RESETF)-- When set, the FIFO pointers of all three
FIFOs are reset. This bit is automatically cleared after resetting the
pointers."
But only the current DMA channel was stopped.
The V4L2_PIX_FMT_YUYV mode uses only on DMA channel. So there should be
no difference to RGB / raw mode.
I will going on with porting my system to 2.6.25 and then test again.
Thanks
