crypto: ccp - Add debugfs entries for CCP information

2017-06-19T06:11:47Z

Expose some data about the configuration and operation of the CCP through debugfs entries: device name, capabilities, configuration, statistics. Allow the user to reset the counters to zero by writing (any value) to the 'stats' file. This can be done per queue or per device. Changes from V1: - Correct polarity of test when destroying devices at module unload Signed-off-by: Gary R Hook Signed-off-by: Herbert Xu

crypto: ccp - Assign DMA commands to the channel's CCP

2017-03-16T09:43:08Z

The CCP driver generally uses a round-robin approach when assigning operations to available CCPs. For the DMA engine, however, the DMA mappings of the SGs are associated with a specific CCP. When an IOMMU is enabled, the IOMMU is programmed based on this specific device. If the DMA operations are not performed by that specific CCP then addressing errors and I/O page faults will occur. Update the CCP driver to allow a specific CCP device to be requested for an operation and use this in the DMA engine support. Cc: # 4.9.x- Signed-off-by: Gary R Hook Signed-off-by: Herbert Xu

crypto: ccp - Clean up the LSB slot allocation code

2016-10-25T03:08:23Z

Fix a few problems revealed by testing: verify consistent units, especially in public slot allocation. Percolate some common initialization code up to a common routine. Add some comments. Signed-off-by: Gary R Hook Signed-off-by: Herbert Xu

crypto: ccp - Refactor code supporting the CCP's RNG

2016-08-09T10:47:09Z

Make the RNG support code common (where possible) in preparation for adding a v5 device. Signed-off-by: Gary R Hook Signed-off-by: Herbert Xu

crypto: ccp - Refactoring: symbol cleanup

2016-08-09T10:47:08Z

Form and use of the local storage block in the CCP is particular to the device version. Much of the code that accesses the storage block can treat it as a virtual resource, and will under go some renaming. Device-specific access to the memory will be moved into device file. Service functions will be added to the actions structure. Signed-off-by: Gary R Hook Signed-off-by: Herbert Xu
