Subject: [PATCH v8 0/6] Use CCP driver to handle PSP I2C arbitration

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.

v7->v8:
 * Pick up tags
 * Drop hunk for error message change
 * Fix kernel robot build failures

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
