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.
