Subject: [PATCH v8 0/6] Use CCP driver to handle PSP I2C arbitration
Date: Mon, 3 Apr 2023 13:32:09 -0500 [thread overview]
Message-ID: <20230403183216.3493-1-mario.limonciello@amd.com> (raw)
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
