Subject: [PATCH v3 4/4] arm64: dts/sdm845: Enable FW implemented safe sequence handler on MTP
Date:   Wed, 12 Jun 2019 12:45:54 +0530
Message-Id: <20190612071554.13573-5-vivek.gautam@codeaurora.org>
In-Reply-To: <20190612071554.13573-1-vivek.gautam@codeaurora.org>
References: <20190612071554.13573-1-vivek.gautam@codeaurora.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Indicate on MTP SDM845 that firmware implements handler to
TLB invalidate erratum SCM call where SAFE sequence is toggled
to achieve optimum performance on real-time clients, such as
display and camera.
