Subject: [PATCH v2 9/9] crypto: ccp: Add doorbell register offset
Date: Thu, 2 Mar 2023 13:42:32 -0600 [thread overview]
Message-ID: <20230302194235.1724-10-mario.limonciello@amd.com> (raw)
In-Reply-To: <20230302194235.1724-1-mario.limonciello@amd.com>
The PSP in Skyrim uses i2c arbitration with a doorbell.
Add this offset so that the communication can work.
