[PATCH v5 0/3] Use CCP driver to handle PSP I2C arbitration

From: Mario Limonciello
Date: Tue Mar 21 2023 - 17:29:04 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.

v4->v5:
* Rebase on crypodev-2.6 with merged patches 1-5 & 7
* Pick up tags
* PCI dependency
* Poll for busy
* Make errors visible rather than debugging only.

Mario Limonciello (3):
crypto: ccp: Bump up doorbell debug messages to error
i2c: designware: Use PCI PSP driver for communication
i2c: designware: Add doorbell support for Skyrim
