How should this go upstream, i.e. are there dependencies? Shall I pick the I2C patches or is it better if all goes via the crypto tree?

There are dependencies in the crypto part from the earlier series that was merged.

Thanks for the heads up. > Herbert, Would you mind to queue these up for -next? I do have some other separate work I will be submitting that is going to layer on top of them, so I'd like to base it off your branch with these landed.

Thanks.
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 drivers/crypto/ccp/platform-access.c | 31 +-- drivers/i2c/busses/Kconfig | 5 +- drivers/i2c/busses/i2c-designware-amdpsp.c | 197 +++++--------------- drivers/i2c/busses/i2c-designware-core.h | 1 - drivers/i2c/busses/i2c-designware-platdrv.c | 1 - include/linux/psp-platform-access.h | 5 +- 6 files changed, 62 insertions(+), 178 deletions(-) base-commit: d6cb9ab4bfeaaa69147948e42d7cff080db82d07
