267 * to issue a DDCB request in a generic way. The request will block
268 * until it finishes or time out with error.
269 *
270 * Some DDCBs require DMA addresses to be specified in the ASIV
271 * block. The interface provies the capability to let the kernel
272 * driver know where those addresses are by specifying the ATS field,
273 * such that it can replace the user-space addresses with appropriate
274 * DMA addresses or DMA addresses of a scatter gather list which is
275 * dynamically created.
276 *
277 * Our hardware will refuse DDCB execution if the ATS field is not as
278 * expected. That means the DDCB execution engine in the chip knows
279 * where it expects DMA addresses within the ASIV part of the DDCB and
280 * will check that against the ATS field definition. Any invalid or
281 * unknown ATS content will lead to DDCB refusal.
