Subject: [PATCH v1 0/3] Add compatibles for different eud access modes

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.

Melody Olvera (3):
  dt-bindings: soc: qcom: eud: Update compatible strings for eud
  usb: misc: qcom_eud: Access mode manager through secure calls
  arm64: dts: qcom: sc7280: Update eud compatible string
