[PATCH v9 0/2] Use CCP driver to handle PSP I2C arbitration
From: Mario Limonciello
Date: Fri Apr 14 2023 - 10:40:33 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.
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
