crypto: ccp - Add support for ringing a platform doorbell

2023-03-17T03:16:43Z

Some platforms support using a doorbell to communicate. Export this feature for other drivers to utilize as well. Link: https://lore.kernel.org/linux-i2c/20220916131854.687371-3-jsd@semihalf.com/ Suggested-by: Jan Dabros Signed-off-by: Mario Limonciello Signed-off-by: Herbert Xu

crypto: ccp - Move some PSP mailbox bit definitions into common header

2023-03-17T03:16:43Z

Some of the bits and fields used for mailboxes communicating with the PSP are common across all mailbox implementations (SEV, TEE, etc). Move these bits into the common `linux/psp.h` so they don't need to be re-defined for each implementation.

crypto: ccp - Add a header for multiple drivers to use `__psp_pa`

2023-03-17T03:16:43Z

The TEE subdriver for CCP, the amdtee driver and the i2c-designware-amdpsp drivers all include `psp-sev.h` even though they don't use SEV functionality. Move the definition of `__psp_pa` into a common header to be included by all of these drivers.
