CCP device (drivers/crypto/ccp/ccp.ko) is part of AMD Secure Processor,
which is not dedicated solely to crypto. The AMD Secure Processor includes
CCP and PSP (Platform Secure Processor) devices.
This patch series adds a framework that allows functional component of the
AMD Secure Processor to be initialized and handled appropriately. The series
does not makes any logic modification into CCP - it refactors the code to
integerate CCP into AMD secure processor framework.

Changes since v3:
- guard sp_dev_resume and sp_dev_suspend with CONFIG_PM
- update Kconfig description for AMD SP device
Changes since v2:
- move the ccp->io_regs initialization before device setup().
- maintain the original Kconfig hierarchy
- rename ccp-{pci,platform}.c -> sp-{pci,platform}.c
- do not fail the module_init() when ccp device is not found
Changes since v1:
- remove unused function [sp_get_device()]
Brijesh Singh (5):
crypto: ccp - Use devres interface to allocate PCI/iomap and cleanup
crypto: ccp - Introduce the AMD Secure Processor device
crypto: cpp - Abstract interrupt registeration
crypto: ccp - rename ccp driver initialize files as sp device
crypto: ccp - remove ccp_present() check from device initialize
