* crypto: img-hash - Fix set_reqsize callWill Thomas2016-08-091-0/+1
| | | | | | | Properly allocate enough memory to respect the fallback. Signed-off-by: Will Thomas <will.thomas@imgtec.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: img-hash - log a successful probeJames Hartley2016-08-091-1/+1
| | | | | | | | | | Currently the probe function only emits an output on success when debug is specifically enabled. It would be more useful if this happens by default.

* crypto: img-hash - Add support for export and importJames Hartley2016-08-091-6/+63
| | | | | | | | | | | | Currently the img-hash accelerator does not probe successfully due to a change in the checks made during registration with the crypto framework. This is due to import and export functions not being defined. Correct this.

* crypto: img-hash - Add suspend resume hooks for img hashGovindraj Raja2016-08-091-0/+27
| | | | | | | | | | | | Current img hash claims sys and periph gate clocks and this can be gated in system suspend scenarios. Add support for Device pm ops for img hash to gate the clocks claimed by img hash.

* crypto: img-hash - Reconfigure DMA Burst lengthWill Thomas2016-08-091-1/+2
| | | | | | | | | | Burst length of 16 drives the hash accelerator out of spec and causes stability issues in some cases. Reduce this to stop data being lost.

* crypto: img-hash - Fix hash request contextWill Thomas2016-08-091-1/+3
| | | | | | | | | | | Move 0 length buffer to end of structure to stop overwriting fallback request data. This doesn't cause a bug itself as the buffer is never used alongside the fallback but should be changed.
