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	[thread overview]
Message-ID: <20190612071554.13573-5-vivek.gautam@codeaurora.org> (raw)
In-Reply-To: <20190612071554.13573-1-vivek.gautam@codeaurora.org>

Indicate on MTP SDM845 that firmware implements handler to
