[PATCH v5 0/3] 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.

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
