Subject: [PATCH v2] arm64: dts: qcom: add IPA qcom,qmp property
Date:   Tue,  1 Feb 2022 09:07:38 -0600
Message-Id: <20220201150738.468684-1-elder@linaro.org>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

At least three platforms require the "qcom,qmp" property to be
specified, so the IPA driver can request register retention across
power collapse.  Update DTS files accordingly.

Signed-off-by: Alex Elder <elder@linaro.org>

v2:  Add devicetree@vger.kernel.org to addressee list.

Dave, Jakub, please let Bjorn take this through the Qualcomm tree.
