[PATCH v6 0/4] Use CCP driver to handle PSP I2C arbitration

Posted by Mario Limonciello 2 years, 10 months ago

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.

Mario Limonciello (4):
  crypto: ccp: Bump up doorbell debug messages to error
  crypto: ccp: Return doorbell status code as an argument
  i2c: designware: Use PCI PSP driver for communication
  i2c: designware: Add doorbell support for Mendocino
