From: George Cherian <george.cherian@xxxxxxxxxx>
This series adds the support for Cavium Cryptographic Accelerarion Unit (CPT)
CPT is available in Cavium's Octeon-Tx SoC series.
The series was tested with ecryptfs and dm-crypt for in kernel cryptographic
offload operations. This driver needs a firmware to work, I will be sending the
firmware to linux-firmware once the driver is accepted.
Changes v2 -> v3
-- Addressed David Daney's comments
- There is not much difference in performance readq/writeq vs
readq_relaxed/writeq_relaxed, so switching to readq/writeq variant.
- Removed the useless bitfield definitions.
- Use GENMASK,dev_to_node() instead of custome functions.
- Use module_pci_driver instead of module_init/exit.
Changes v1 -> v2
-- Addressed a crash issue when more gather components are passed.
-- Redo the cptvf request manager.
- Get rid of the un necessary buffer copies.
-- s/uint*_t/u*
-- Remove unwanted Macro definitions
-- Remove the redundant ROUNDUP* macros and use kernel function
-- Select proper config option in Kconfig file.
-- Removed some of the unwanted header file inclusions
-- Miscellaneous Cleanup
