From 5342f1df8f50df3cec6e015beefc4eca79eb858d Mon Sep 17 00:00:00 2001 From: Stephan Gerhold Date: Tue, 15 Sep 2020 09:12:13 +0200 Subject: [PATCH] arm64: dts: qcom: msm8916: Drop qcom,tcsr-mutex syscon The hwlock device node does not (directly) use memory resources of the SoC, so we should move it outside the "soc" node. However, as of commit 7a1e6fb1c606 ("hwspinlock: qcom: Allow mmio usage in addition to syscon") we can now assign the memory region directly to the hwlock device node. This works because the register space used by it is actually separate and not used by any other components.
