I checked the code again. It seems I do not miss the call to
dmaengine_submit().
There are five places where call the dmaengine_submit() by
start_dma_with_bch_irq()/start_dma_without_bch_irq():
gpmi_send_command(),gpmi_send_data(),gpmi_read_data(),
gpmi_send_page(), gpmi_read_page().
The gpmi nand code runs well in previous mxs-dma code.
