From: Alex Elder Date: Tue, 1 Feb 2022 15:02:04 +0000 (-0600) Subject: dt-bindings: net: qcom,ipa: add optional qcom,qmp property X-Git-Tag: v5.15.73~5029 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=587ced6b8cf350616728e17cbcde9ae8a333122a;p=platform%2Fkernel%2Flinux-rpi.git dt-bindings: net: qcom,ipa: add optional qcom,qmp property commit ac62a0174d62ae0f4447c0c8cf35a8e5d793df56 upstream. For some systems, the IPA driver must make a request to ensure that its registers are retained across power collapse of the IPA hardware. On such systems, we'll use the existence of the "qcom,qmp" property as a signal that this request is required.
