The driver is separated by functional parts. The core part implements a platform driver probe and remove callbaks. The probe enables clocks, checks crypto version, initialize and request dma channels, create done tasklet and init crypto queue and finally register the algorithms into crypto core subsystem. - DMA and SG helper functions implement dmaengine and sg-list helper functions used by other parts of the crypto driver. - ablkcipher algorithms implementation of AES, DES and 3DES crypto API callbacks, the crypto register alg function, the async request handler and its dma done callback function. - SHA and HMAC transforms implementation and registration of ahash crypto type. It includes sha1, sha256, hmac(sha1) and hmac(sha256). - infrastructure to setup the crypto hw contains functions used to setup/prepare hardware registers for all algorithms supported by the crypto block. It also exports few helper functions needed by algorithms: - to check hardware status - to start crypto hardware - to translate data stream to big endian form Adds register addresses and bit/masks used by the driver as well.
