Subject: [PATCH v2 0/9] Export platform features from ccp driver
Date: Thu, 2 Mar 2023 13:42:23 -0600 [thread overview]
Message-ID: <20230302194235.1724-1-mario.limonciello@amd.com> (raw)
The i2c-designware-amdpsp driver communicates with a platform
features mailbox provided by the PSP. The address used for
communication is discovered via a non-architecturally
guaranteed mechanism.
To better scale, export a feature for communication with platform
features directly from the ccp driver.
v1->v2:
* Pick up tags
* Fix dependencies
* Add support for Skyrim (3 new patches in series)
Mario Limonciello (9):
crypto: ccp: Drop TEE support for IRQ handler
crypto: ccp: Add a header for multiple drivers to use `__psp_pa`
crypto: ccp: Move some PSP mailbox bit definitions into common header
crypto: ccp: Add support for an interface for platform features
crypto: ccp: Enable platform access interface on client PSP parts
i2c: designware: Use PCI PSP driver for communication
crypto: ccp: Add support for ringing a platform doorbell
i2c: designware: Add doorbell support for Skyrim
crypto: ccp: Add doorbell register offset
