The APB DMA block handles DMA transfers to and from some peripherals in the Tegra SOC. It reads from sequential addresses on the memory bus, and writes repeatedly to the same address on the APB bus. Two transfer modes are supported, oneshot for transferring a known size to or from a peripheral, and continuous for streaming data. In continuous mode, a callback occurs when the buffer is half full to allow the existing data to be handled and a new request queued.x v2 changes: dma API no longer uses PTR_ERR Signed-off-by: Erik Gilling <konkers@android.com> Signed-off-by: Colin Cross <ccross@android.com> |
