From ac62a0174d62ae0f4447c0c8cf35a8e5d793df56 Mon Sep 17 00:00:00 2001 From: Alex Elder Date: Tue, 1 Feb 2022 09:02:04 -0600 Subject: dt-bindings: net: qcom,ipa: add optional qcom,qmp property 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.
