33 *
34 * @dev_tx: mapping between destination event line and io address
35 * @dev_rx: mapping between source event line and io address
36 * @disabled_channels: A vector, ending with -1, that marks physical channels
37 * that are for different reasons not available for the driver.
38 * @soft_lli_chans: A vector, that marks physical channels will use LLI by SW
39 * which avoids HW bug that exists in some versions of the controller.
40 * SoftLLI introduces relink overhead that could impact performace for
41 * certain use cases.
42 * @num_of_soft_lli_chans: The number of channels that needs to be configured
43 * to use SoftLLI.
44 * @use_esram_lcla: flag for mapping the lcla into esram region
45 * @num_of_memcpy_chans: The number of channels reserved for memcpy.
46 * @num_of_phy_chans: The number of physical channels implemented in HW.
47 * 0 means reading the number of channels from DMA HW but this is only valid
48 * for 'multiple of 4' channels, like 8.
