From e1c13aed4a1641550e8c9518c96f016e1d52d09b Mon Sep 17 00:00:00 2001 From: Yijie Yang Date: Tue, 11 Aug 2026 16:46:47 +0800 Subject: dt-bindings: interconnect: qcom-bwmon: Add Maili cpu-bwmon compatible Add the Qualcomm Maili SoC compatible string for the CPU bandwidth monitor (BWMONv4). This falls back to the sdm845-bwmon compatible, consistent with the existing pattern used by other recent SoCs such as sm8750 and kaanapali.
