Subject: [PATCH v9 0/2] 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.

v8->v9:
 * Drop v8 patches 1-4 as they're merged now
 * Pick up tags for v8 patches 5-6
 * Repost to linux-crypto as this needs to merge through crypto tree.

Mario Limonciello (2):
  i2c: designware: Use PCI PSP driver for communication
  i2c: designware: Add doorbell support for Mendocino
