-From: Fabio Estevam <fabio.estevam@nxp.com>
-
-Currently the mxs-dcp driver fails to probe:
-
-mxs-dcp 80028000.dcp: Failed to register sha1 hash!
-mxs-dcp: probe of 80028000.dcp failed with error -22
-
-This happens since commit 8996eafdcbad ("crypto: ahash - ensure statesize
-is non-zero"), which requires statesize to be filled.
-
-Other than filling statesize, we also need to provide the import/export
-functions.
-
-Based on the implementation of the sahara and caam drivers.
