Subject: [PATCH v1 0/3] Add compatibles for different eud access modes
Date: Wed, 7 Aug 2024 11:32:01 -0700 [thread overview]
Message-ID: <20240807183205.803847-1-quic_molvera@quicinc.com> (raw)
When enabling eud on some devices, a crash can happen when trying to
access mode manager registers, since some devices require that these
be accessed securely. To support this usecase, update the compatible
strings and add driver functionality to distinguish between secure
and non-secure euds and avert these kinds of crashes.
