The dma_reload() is useful when there's the need to immediately and quickly restart the DMA for a new transfer when the current one is completed. If the operation is not done quickly there might be underrun or overrun errors and the data flow is broken. The dma_reload() just does the minimum operations required, i.e. programming the new src/dst addresses and transfer size. Signed-off-by: Armando Visconti <armando.visconti@st.com> |
