Subject: [PATCH] arm64: dts: qcom: add IPA qcom,qmp property
Date: Tue, 1 Feb 2022 08:07:23 -0600 [thread overview]
Message-ID: <20220201140723.467431-1-elder@linaro.org> (raw)
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>
