Subject: [PATCH 1/3] dt: psci: Add arm,psci-sys-reset2-type property
Date:   Fri, 21 Feb 2020 15:28:03 -0800
Message-Id: <1582327685-6316-2-git-send-email-eberman@codeaurora.org>
In-Reply-To: <1582327685-6316-1-git-send-email-eberman@codeaurora.org>

Precedence: bulk

Some implementors of PSCI may relax the requirements of the PSCI
architectural warm reset. In order to comply with PSCI specification, a
different reset_type value must be used. The alternate PSCI
SYSTEM_RESET2 may be used in all warm/soft reboot scenarios, replacing
the architectural warm reset.
