[PATCH v7 0/6] Use CCP driver to handle PSP I2C arbitration

From: Mario Limonciello
Date: Wed Mar 29 2023 - 18:08:15 EST



The CCP driver now has symbols that can be used by i2c-designware-amdpsp
to handle the communication regarding i2c arbitration with the PSP for
both Cezanne and Mendocino based designs.

Utilize those symbols.

Mario Limonciello (6):
crypto: ccp: Drop extra doorbell checks
crypto: ccp: Bump up doorbell debug message to error
crypto: ccp: Return doorbell status code as an argument
crypto: ccp: Use lower 8 bytes to communicate with doorbell command
register
i2c: designware: Use PCI PSP driver for communication
i2c: designware: Add doorbell support for Mendocino
