From bc6776fab8455762089274d469a67d104e3b96ae Mon Sep 17 00:00:00 2001 From: Shivnandan Kumar Date: Wed, 16 Jul 2025 14:25:47 +0200 Subject: [PATCH] arm64: dts: qcom: sm8750: Add BWMONs Add the CPU BWMONs for SM8750 SoCs. Notably, the one related to cluster0 requires that it's mapped with the nE memory attribute. This is specific to a single instance, on this platform only and should not be mimicked elsewhere.
