2015-02-27crypto: ccp - Convert calls to their devm_ counterpartsTom Lendacky1-1/+1
Where applicable, convert calls to their devm_ counterparts, e.g. kzalloc to devm_kzalloc. Signed-off-by: Tom Lendacky <[email protected]> Signed-off-by: Herbert Xu <[email protected]>

2014-09-24crypto: ccp - Check for CCP before registering crypto algsTom Lendacky1-0/+14
If the ccp is built as a built-in module, then ccp-crypto (whether built as a module or a built-in module) will be able to load and it will register its crypto algorithms. If the system does not have a CCP this will result in -ENODEV being returned whenever a command is attempted to be queued by the registered crypto algorithms. Add an API, ccp_present(), that checks for the presence of a CCP on the system. The ccp-crypto module can use this to determine if it should register it's crypto alogorithms.

2014-07-23crypto: ccp - Base AXI DMA cache settings on device treeTom Lendacky1-1/+1
The default cache operations for ARM64 were changed during 3.15. To use coherent operations a "dma-coherent" device tree property is required. If that property is not present in the device tree node then the non-coherent operations are assigned for the device. Add support to the ccp driver to assign the AXI DMA cache settings based on whether the "dma-coherent" property is present in the device node. If present, use settings that work with the caches. If not present, use settings that do not look at the caches. Signed-off-by: Tom Lendacky <[email protected]> Signed-off-by: Herbert Xu <[email protected]>
2014-06-20crypto: ccp - Add platform device support for arm64Tom Lendacky1-0/+34
Add support for the CCP on arm64 as a platform device. Signed-off-by: Tom Lendacky <[email protected]> Signed-off-by: Herbert Xu <[email protected]>
2014-02-09crypto: ccp - Perform completion callbacks using a taskletTom Lendacky1-4/+17
Change from scheduling work to scheduling a tasklet to perform the callback operations. Signed-off-by: Tom Lendacky <[email protected]> Signed-off-by: Herbert Xu <[email protected]>
2014-01-15crypto: ccp - CCP device enabled/disabled changesTom Lendacky1-1/+14
The CCP cannot be hot-plugged so it will either be there or it won't. Do not allow the driver to stay loaded if the CCP does not successfully initialize. Provide stub routines in the ccp.h file that return -ENODEV if the CCP has not been configured in the build.
