Subject: [PATCH] arm64: dts: qcom: add IPA qcom,qmp property
Date: Thu, 21 Apr 2022 16:59:53 -0500 [thread overview]
Message-ID: <20220421215953.1750848-1-elder@linaro.org> (raw)
commit 73419e4d2fd1b838fcb1df6a978d67b3ae1c5c01 upstream.
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.
Cc: <stable@vger.kernel.org> # 5.17.x
Fixes: 1aac309d3207 ("net: ipa: use autosuspend")

The code for this feature was included in the v5.17 cycle, but the
DTS file updates were not accepted until v5.18-rc1.
