Subject: [PATCH -next 0/2] Add i2c arbitration support for new SoCs
Date: Fri, 16 Sep 2022 15:18:52 +0200 [thread overview]
Message-ID: <20220916131854.687371-1-jsd@semihalf.com> (raw)
This patchset comprises changes into i2c-designware-amdpsp.c module
which aims to add support for new SoCs, while keep backward
compatibility with Cezanne platforms.
Beside new algorithm introduced for the PSP-x86 communication, it also
switches from MSR/MMIO access to SMN (System Management Network) since
only the latter is working on both old new revisions of SoCs.
