For each packet data segment + * processed, the DSE triggers the RDR Manager to write the updated RD. + * If triggered to update, the RDR Manager sets up a DMA operation to + * copy the RD from the DSE to the correct location in the RDR. + * + * Data Store Engine(DSE) - It is responsible for parsing the prepared RD + * and setting up the required control and packet data DMA transfers from + * the processing engine to system memory. + * + * Advanced Interrupt Controllers(AICs) - receive interrupt request signals + * from various sources and combine them into one interrupt output. + * The AICs are used by: + * - One for the HIA global and processing engine interrupts. + * - The others for the descriptor ring interrupts. + */ + +/* Cryptographic engine capabilities */ +struct mtk_sys_cap { + /* host interface adapter */ + u32 hia_ver;
