rt2800: add helpers for reading dma done index For mmio we do not properlly trace dma done Q_INDEX_DMA_DONE index for TX queues. That would require implementing INT_SOURCE_CSR_*_DMA_DONE interrupts, what is rather not worth to do due to adding extra CPU load (small but still somewhat not necessary otherwise). We can just read TX DMA done indexes from registers directly. What will be used by watchdog. Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
